My experience with Dr. Vargas was exceptional. He is a caring, kind, and compassionate doctor regarding my fears and concerns. He took time to to answer my questions, and I never felt rushed. He was very knowledgeable and I felt that he would be able to repair my severe dental condition. I look forward to working with Dr. Vargas and he’s team.
For someone like myself who has a lifelong fear of sitting in the dentist chair, Chappaqua smiles is excellent. From the dentists, hygienists and admin staff I am always immediately put at ease. This is a great practice. Highly recommend.
Diane has been absolutely wonderful. She has been my hygienist for many years. Always pleasant, professional and prompt. Most importantly, she maintains my oral health.
Dr Vargas is very knowledgeable and genuinely cares about his patients. His staff are kind and attentive to patients needs throughout the visit
Dr. Vargas and his team are the best in the business. The new office in Chappaqua is clean, bright and inviting. I’ve referred many friends and family to his practice and they’ve been uniformly delighted with his care and personal attention.
I’m a 55 year old woman who has been terrified of going to the dentist just about my entire life. In the past I have literally gone 5-8 years between dentists visits . I take very good care of my teeth so there has never been an emergency to go . When I do find a dentist I’m the one who always cancels at least once before I finally go for that cleaning I know I need . The fear is so real and at times I have actually felt like I’m going to pass out !About two years ago my husband made me go to dr. Vargas and I’m now going regularly for the first time in my life!They are all so gentle and considerate, they have managed to make me feel good about going ! I have even had work done , fixing some teeth that were slightly cracked and old fillings needed to be replaced! Would highly recommend! I’m never going anywhere else from now on !
Pleasant staff, personable hygienist who made a cleaning pain free. Doctor was very clear in future procedures to facilitate good dental health. Impeccable facility.
First time visiting this office and the staff was super helpful and friendly and very patient-centric. Beautiful and meticulously clean office. Dr. Vargas was very congenial and a good listener to patient concerns.
I have being visiting Dr Vargas for a few years now and have always felt comfortable and at ease while here. The staff at Chappaqua Smiles always makes you feel welcome and reassured that they have your best interest at heart. I’ve had a few different procedures done and have been very happy with the results. In addition they inform you of steps you can take to prevent further damage to your teeth, in my case it was a (guard) to prevent grinding. Which was never told to me by previous dentist. Dr. Vargas always explains the options that are available to you which helps you make a logical decision and best choice for your needs/situation. I look forward to having Dr. Vargas and his staff taking care of all my dental needs.May 2023- Recent visit to the new office. It shows the importance that is placed on patient convenience and comfort. I highly recommend Chappaqua Smiles for your dental needs.
I seldom write reviews but I would like to say thank you to Dr. Vargas and his entire incredible staff. Dr. Vargas is warm & friendly. He is very knowledgeable & professional. Most important of all, he very much cares about his work and his patients. I had a chipped tooth and many other dental issues. I’m always nervous about visiting a dental office but Dr. Vargas made me feel comfortable, it was a painless experience. Dr. Vargas has a lot experience which he funnels into providing the best service to his patients. I highly recommend Dr. Vargas to anyone in need of dental work.
I needed an emergency appointment and got in same day. Couldn’t praise them enough. Excellent and professional in every way
Diane is the best! Professionally astute! Gentle touch when cleaning friable areas.Dr. Vargas took care of a temporary bridge post-periodontal procedure. Terrific dental practice!
Had a great first experience at CS. They have a beautiful office with great views. We parked right outside (for free! Where does that happen in Westchester?). I only had to wait a few minutes past my appointment time. The hygienist was friendly and thorough, and the Doc was positive, helpful, and quick. For the suggested next steps they are helping sort out the insurance matter, looking forward to my 6 month check-up.
Best doctors office ever, awesome staff … so helpful in every way possible… As for doctor Vargas he give hope to my daughter where there was no hope and for that I will always put him above any doctor in the world and be forever grateful ??Thank you always !!!!
Dr. Vargas, Linda and the staff are always, kind, knowledgeable and sensitive to client’s needs. A great place to go for your dental work!
Today was my 5 year old daughters first trip to the dentist and it went great thanks to the team at Chappaqua Smiles. My whole family now goes to Dr Vargas and his team and it’s a positive experience every time!
The office staff was great and very professional Dr. Vargas is one of the most caring Dentist I have ever encountered. He puts you at ease the minute he enters the room His bedside manner goes well beyond 5 stars. His work in implants is exceptional. When you see the beautiful smiles on his patients after he completed his work was breathtaking and did bring tears to my eyes. I knew how they felt. You do not feel shame or guilt in his office just hope and happiness that your smile will be as beautiful as his other patients
I have known Dr. Vargas since he has started his practice. He is an authentic person, who is deeply compassionate with every situation. I hold him in the highest regard, which is why I have recommended him to all family members and friends. Most importantly, he creates an experience that is comfortable and secure. Anyone can trust that they are in good hands with Dr. Vargas and his exceptional staff.
I had quite a lot of work done over the past year. They were at all times professional, thoughtful and extremely helpful with every aspect of my treatments. Well-equipped and well staffed, Dr. Vargas and the hygienists are first rate.
Arriving at the office of Chappaqua Smiles I received a cordial welcome and immediately met with Dr. Vargas! Films were taken and within a few minutes Dr. Vargas returned and gave a very clear and concise evaluation of the X Rays! The Dr. and I had a lengthy discussion of what he saw on the films and what corrective measures might be undertaken! Given three treatment options, I left the office relieved and much more knowledgeable! First visit was very pleasant and rewarding!
Couldn’t be more happy with our experience at Chappaqua Smiles. Courtney was so wonderful with my 2 boys (2 and 4) with their cleanings. She knew exactly what to do an what to say and just went in there and did it. They went from being apprehensive to loving the experience. Dr. Vargas was wonderful too…very thankful to have found our family dentist location.
My experience was great as always. Professional and caring. Office was immaculate. Dr Lara & hygienist were wonderful, entire staff was wonderful. Thank you Chappaqua Smiles.
Dr Vargas is great! He’s attentive, he knows exactly, the standard of care that I’m looking for. He’s a perfectionist & I love that about him. He pays attention to detail. The auxiliary staff in his office are very professional & courteous.
Our entire family has been going here since we moved to town 6 years ago. We love them – they take such good care of everyone, and they really embody the notion of a family dental practice. Can’t recommend them enough, and so happy that they happen to be located in our town.
Yesterday I had my teeth cleaned. Courtney did an excellent job, taking about an hour. My dental implants really needed a thorough cleaning after 8 months since being cleaned, and it didn’t hurt as much as I thought it would. Thank you!I’ve been a patient of Chappaqua Smiles since 2017 and I love my wonderful smile. Before then I had full dentures, both upper and lower.I had serious gum disease, but the dentures had some serious disadvantages.Bonnie S.
Amazing place I feel really comfortable and Dr Vargas is very thoughtful and considerate as I am a nervous patient. 5 star rating.
I have been a patient of Dr. Vargas’ for many years and he has provided superior dental care for me and my family. He knows his stuff and is a great guy, too.
My experience at chappaqua smiles has been nothing short of amazing, there’s no other place I’d rather go to get my teeth cleaned. The care you get there is unlike anything I’ve experienced and I couldn’t be happier I’ve been going to them for the past 8+ years.
My experience at chappaqua smiles has always been an incredible experience, the care you get there is unlike anything I’ve experienced elsewhere. I’m so happy that I’ve been going to them for 8+ years now and there’s no where else I’d rather go to get my teeth cleaned.
Great check up with Dr. Vargas and staff. Very happy with the safety protocols in place and the quality of care is always top notch.
Dr. Vargas is excellent!! The office is very clean, and the hygienists and staff are very competent, thorough and friendly. Always a great experience!
I like the front staff and Dr. Vargas. I have always had problems with my teeth and my husband is never happy when problems end up costing over what the insurance covers. I was so disappointed when I heard that all my Xrays and all my issues had been chatted about and laughed about when my husband was in last, considering it had been an issue between the two of us about “how much my teeth have cost him”. Professionalism does include keeping someone’s files private whether they are married or not. I like the hygienist but our whole family finds she is quite heavy handed and none of us come out of there saying how gentle she is. I still believe they do a good job, but we are going to try a new dentist this year. Sorry
Dr. Vargas has done excellent work on an on-lay and two crowns. He and his staff are extremely professional and friendly. If you are afraid of pain he does an amazing job of getting me numb!
I got a last minute appointment through the receptionist Michele with Dr. Lara. Michele really worked hard to get me in and she succeeded! I am very grateful. Dr. Lara was very reassuring and made a couple of recommendations.I trust her opinion. In addition, my daughter goes for dental care to Chappaqua Smiles and is very happy too. The office follows covid safety rules so I was comfortable going there. The staff in the office was friendly and courteous. All around a very good experience.Just had another visit and tooth cleaning (after a year and a half!) As before, my visit was great. The hygenist Calila(sp?) was very thoroughand understanding and I will be going back again in July for some minor work. Very nice staff and Dr. Lara is very easy to communicate with and very professional. Highly recommend .
My first time in the office the staff is very friendly.My dentist I saw O’Shaughnessy D.D.S was friendly and explained everything that needs to be done to my tooth
Dr. Vargas and his staff were amazing! They immediately made me feel at ease. Dr. Vargas maintained a friendly, comfortable atmosphere while also ensuring that he explained each step of what was happening, what the options were, and making sure I had the best dental care possible. We drove from 3 hours away to see him, and it was well worth our time. I truly feel like he cares about his patients and the outcome of his care. I would highly recommend him to anyone… Even with a long drive! ?Update: I just had my final appointment with Dr. Vargas and the case for my implant was placed. It looks amazing! I can’t tell the difference between the implant and my other teeth. I am incredibly happy with how it turned out! ?
I had a great experience and felt completely safe. Everyone was very professional. Courtney was a true professional.
EXcellent and professional office staff. Very attentive to details and cleaniless post-Covid. Highly recommended.
What a great practice, and Dr. O is the best! Going to the dentist has never been my favorite, but that has changed thanks to her wonderful bedside manner. She always makes us feel comfortable, and takes time to explain options for treatment. Our family recommends Dr. O and her team very highly!
New to Chappaqua and found a place that makes me smile Thanks! SCleaning and check up today was professional and made me feel like I could do better and was coached on realistic options. Thanks! S
I have been a patient of Dr. Oshaughnessy for 5 years at Chappaqua Smiles. She has exemplified expertise in the medical dental field profoundly. From a simple cavity to major surgery Dr. Oshaughnessy has gone above and beyond her call of duty with her proficiency.
I started seeing Dr Vargas and his team at Chappaqua Smiles a few years back. Now my wife, my mom, my dad, my sister and a bunch of my friends go there as well. That should say enough about how wonderful the experience is there.
Dr Vargas and all.the staff were so professional, courteous and knowledgeable. Really a great practiceJust had another visit at Chappaqua Smiles. DR vargas and his staff made the visit painless. This is a great practice to have your dental work done at.
Had dental emergency..saw me right away despite the fact I was a new patient. Very compassionate and efficient. Welcoming office staff. Permanently switched to this practice. Highly recommend.
Dr Vargas gave me four new veneers and even though I hate the drill, he was gentle, friendly and skillful. I love my new teeth and I love the staff. Everyone is amazing.
I did teeth cleaning with Dr. Lara O’Shaughnessy. She has done a great job. No hurt no pain!! I just got my clean teeth back. Thank you so much
Whether I’m with Dr.O or Dr. Vargas it’s always 5 star treatment. I literally flew back to NY from the west where I live now to come to this office. No other dentist/ team of hygienists will do.
Today was my first appointment, but it made the 3 hour trip worth while. Lovely, capable, caring staff and with in moments of speaking with Dr Vargas you are at ease. He listens; validated all my questions and concerns. I look forward to my next visit and feeling great about my smile again.
I have been a patient of Dr.Vargas for several years and highly recommend him. His disposition and bedside manner are excellent and hard to find. Recently, I visited Dr. Vargas for a diastema closure and couldn’t be happier with the results. His attention to detail is evident in the final product. Thanks again! Wish I had done it sooner.
Going to the dentist can be extremely stressful for most everyone,myself included.However,I am extremely lucky to have been referred to Dr.Vargas and his practice.The entire staff are wonderful, knowledgeable and accessible.Everyone puts you at ease and explain what is being done -which definitely helps a “chicken little”like myself.Thanks to everyone at Chappaqua Smiles for getting my smile back on track!
My whole family have been patients of Dr. Vargas since day one. He and Dr. O’Shaunessy and hygienists,Debbie and Diane are so very totally professional, painless, and so friendly. is great. Linda is a great dental assistant. Michelle is so sweet and friendly, and takes excellent care of insurance.We know them all for take years and exchange family talk.They take me the same day when we have emergencies. I highly recommend Chappaqua Smiles and wouldn’t go anywhere else. Every visit is nice, believe it or not. Everybody is so friendly. You can tell how skilled and precise the doctors and hygienists are. Odd, but an enjoyable experience and always leave happy with better teeth.
My experience at Chappaqua Smiles has been life changing. Before I went to Chappaqua Smiles, I had severe gum recession from teeth grinding that I did not even know about. I also was not happy with how my teeth had started to become crooked, but did not know what to do about it. With in my first few visits at Chappaqua Smiles, I had all of my problems addressed and solved (or at least on a path to a solution). Dr. Vargas is absolutely outstanding, and so is his staff and the office environment in general. Dr. Vargas has the best personality; so friendly, funny, and makes you feel totally at ease and confident that everything will turn out great. With his suggestion, I went ahead with 8 months of Invisalign. My teeth came out fantastic! They are not only perfectly straight, but also white and bright. At the end of the treatment, there was one tooth I was still unhappy with. Dr. Vargas had an instant solution to fix the look of the tooth with bonding. The results were a perfect smile. I couldn’t be happier with Chappaqua Smiles and I would highly recommend it to anyone looking for anything from a simple cleaning to a complicated treatment!
Dr. Vargas and his team are great. Super friendly, great work and you can even get a cocktail if you ask nicely!
Dr. Vargas is the best dentist. He truly takes pride in his work. His staff is professional and friendly. Good energy in the office. I highly recommend Chappaqua Smiles!!
I am always treated like family when I come here!! I have had much work done recently. Dr. Vargas (and his assistant Linda) were there for me every step of the way……including being present for my surgery…..in another office!!I actually smile at the thought of interacting with all the people in the office. The experience is much different from what previous offices were like. They are like family.
Drove all the way here, had to wait outside of the office. I let the receptionist know that I have a condition and a note from my doctor that I won’t be wearing a mask. They would not allow me in the building, so I cancelled my appointment and will no longer be a client of the firm. Also this firm is infamous for jacking up the bills, happened to me and to my sister. I will go support another business instead of this place.
I went here to today for the first time because my dentist of 23 years does not accept my new insurance. I was so impressed with everyone in this office. They were all friendly and helpful, and my hygienist Diane who did the cleaning was so knowledgeable. Apparently I have been flossing incorrectly, but no one else ever taught me properly! She educated me as she cleaned, and she took before and after pictures to emphasize where I need to focus during my oral care routine. I absolutely recommend this office.
My husband and I just switched to Dr. Vargas because our dentist retired. I am very anxious about going to the dentist, but Dr. Vargas and the entire staff made me feel at ease. They couldn’t be nicer!!! We also feel he is very skilled and competent. We both highly recommend him.
Dr. O’Schnaugessey has an attention to detail like no other dentist I’ve been to, and I’ve had a lifetime of various issues that cause me to grip the arms of the dental chair to a point it has always been noticed. Dr O’Schaugnessey doesn’t settle for less than perfection in her work. She continuously kept me informed all through the process at each visit. She corrected several issues I had, including one tooth where her fix gave me a new quality of life. Not only am I back to 100%, but my teeth have nice new fillings that are unnoticeable.
Had deep cleaning done today. While painful, the hygienist made me feel comfortable throughout the entire procedure. I am really satisfied with the work they have done.
I was having problems with a crown, called the office in the morning, and had it repaired 15 minutes later! Both of the dentists are friendly and do great work. Their staff is also a pleasure to deal with.
Dr Vargas and his excellent staff make dental care Something of a pleasure instead of a fear.Let’s face it no one “likes “ going to the dentist but it’s really hard not to enjoy the experience here.Dr. Vargas and hygienist Diane are the consummate professionals but more than that they are truly caring and compassionate. I couldn’t recommend them more highly!Dr. Eric Karle
I have never in my 55 years of life looked forward to seeing my dentist as I do today. Chappaqua Smiles and Dr Vargas have a great team of Professional, sincere, and friendly dental services. Not to mention that they have given me my perfect smile once again. Love them!!!!
The staff at chappaqua Smiles is always very friendly, courteous and professional. They always run in time – I can’t remember a time I have had to wait more than 5 minutes for my appointment. Dr. Vargas is so nice and reassuring and makes me feel confident about any procedure I might have to undergo. As the staff there knows, I am pretty phobic about going to the dentist, even for a cleaning, but they ease my anxieties every time. I highly recommend them!
I truly love everything about this dental office. It all begins with Michele and Jamie at the front desk who always greet you with a warm smile and assist in making appointments that fit my schedule. Everyone from the awesome hygienists, Debbie and Diane, to the dental assistants are reassuring and efficient. Dr. Vargas is an amazing dentist. One of my favorite things about him is that he communicates about all that needs to be done and what he is doing at the time the dental work occurs. Dentist visits can be stressful but Chappaqua Smiles does everything in their power to make them less so. I highly recommend this office.
The staff was exceptionally friendly as soon as I walked in the door. Diane, my hygienist, was incredibly efficient and super knowledgeable. Dr. Vargas is wonderful and genuine. I’m glad to have found such an awesome dental group nearby.
I had a crown installed today and my bite feels perfect! Such positive experiences at this office — no wait time, easy to make appointments, plenty of parking (front on the street and in the back), clean & modern space. The office staff is helpful and friendly. My cleaning with the hygienist was thorough without being painful. And both dentists have exceeded my expectations.
We had a wonderful experience at Chappaqua Smiles. The office is lovely and the staff are very warm, welcoming, and efficient. I was very impressed with every aspect of the practice and would highly recommend their dentistry services for either kids or adults.
Everyone I’ve dealt with at Chappaqua Smiles is professional and friendly. They take the time to get to know their patients. From the greeting you get when you enter, from the hygienists to Dr Vargas himself, you feel comfortable the moment you become a patient. Dr. Vargas is knowledgeable and takes the time to explain things. The hygienists go out of their way to ensure your experience is as relaxed and easy as possible. Best dental care I’ve ever received.
I have been going to Dr. Vargas for years; wonderful experience every time. Front desk is wonderful and great to work with when scheduling/ rescheduling an appointment, fairly new lobby is very warm and modern. Hygienists are experienced and very thorough. Dr. Vargas is friendly, caring, and involved. I would highly recommend.
