Our patients leave smiling
Ramapo Dental is wonderful. I have been coming here since I was a kid and now I take my kids (34 years in all). I live in Brookyn. And travel 1.5 hours to get here!!! Lonnie and Denise are wonderful hygienists, thorough, funny and warm — it’s hard for them to clean my teeth when I’m laughing so much. The front desk staff are always warm and friendly and make sure I make it to my…
My husband, 10 year old son and I have been patients of Ramapo Dental Care for quite a long time. We couldn’t be happier with Carol, our hygienist. She’s fantastic and always keeps our minds off what she’s doing! Dr. Gusmano is great and has never caused an “owie!” while taking a look in our mouths. I’d recommend Ramapo Dental to anyone who asks.
Why this isn’t your average Dental Practice… Growing up I had some pretty miserable experiences at the dentist, from shoddy work to work that didn’t need to be performed. I never liked going to the dentist, but over time it got worse and worse until it got to the point where my anxiety prevented me from going. My Mom knew I had not been to the dentist in years and when she found…
Everyone in this office was so nice! Everyone said hello and was smiling. My dentist Dr. Chinchetti was great. it was my first time there and I was so nervous but he took the time to explain things to me and it really made me feel like he genuinely cared about me. Carol was amazing. She is such a nice lady. She really made me feel very comfortable and she is so caring. Everyone is super kind and g…
Yep, even getting a root canal I had a good time. Steve is a true professional in his field , no pain but great Elvis music n a few good laughs. I lost my fear of going to the dentist thx to him. He can never move away n if he does I have to move w him. So people, go see him, It will be the best decision u ever make.
Dr. Chichetti has been taking care of my dental needs for many years. I wouldn’t go to anyone else. He always looks for the most reasonable solution for your dental problems and NEVER takes a cookie cutter approach to your issues. He is thoughtful, extremely creative, caring and compassionate. The office staff and assistants are friendly, courteous and professional in every way.
I have been going to Ramapo Dental for over 30 years and have never had a bad experience. The staff is very friendly and the Dentists are dedicated to providing quality service,

Best dental care around! Super friendly, professional staff. Quick and painless appointments. Actually cared about my well being and followed up on how I was doing. Were able to give me an appointment within a week! Would recommend highly without hesitation.
Lonnie and Dr. Chichetti are the best! And the front desk is wonderful and accommodating.
This place is fantastic! In fact, even after moving an hour away, our family decided it was worth it to us to make the trip to have them take care of our teeth because they are so nice and such a great job with caring for our teeth. This was was my daughter’s first cleaning, and she was a bit nervous, but I was so happy with how they make this a fun experience for her. She loved her first trip t…
Amazing office ! Kind,caring and professional! I Recommend this office to everyone.
This place is amazing! No long waits, super friendly too. I had a bad history with dentist not being able to numb me right before doing a filling. I went here and the Dr. I had made me feel comfortable and I did not feel a thing!!!!!
Great staff and service. Carol and Robyn are fantastic!

I was in bad pain from a tooth that needed to be extracted. They gave me an appointment that day. The extraction was done very professionally although it was a difficult case and it healed beautifully. Thank You so much!!!!

I’ve been coming here for about 10 years now and it’s always been a pleasure going to the dentist. My hygienist Lonnie is amazing and both Drs. Gusmano and Chichetti are top notch.

I am a long term patient in this office and am continually impressed by the staff friendliness as well as the care and concern shown to patients. My hygienist, Claire, is the best! Always thorough and professional.
Everyone in the office is very accommodating. It is easy to get an appointment even last minute. They run on schedule and I’ve never had to wait more than a couple minutes to be seen.
Carol was excellent. The staff was so professional from the moment I walked in to the moment I walked out everything was perfect.
Always very nice and on time with there schedule. Carol is the best !
Everyone here is professional, welcoming and talented. I always know I will get the best of care.
Both Dr. Steve and Carol are the best, they are family. Both my wife and I highly recommend the practice because of their excellent care, tremendous personalities and the friendly atmosphere that begins when you first arrive and as you leave the office..

Another excellent visit. Very short wait and very professional job.
I went into the office a couple of days ago to get an impression done for my crowns. Before I arrived I felt anxious and had many concerns but when I arrived for my appointment I felt the anxious feelings go away. The staff sets a relaxed and welcoming tone, and I feel as if I’m treated like a family member. Dr. Gusmano is wonderful, he always answers any questions and concerns with a thorou…

I have been going to ramapo dental care since I was a kid. All the people working there from: the front desk, hygienists ,and doctors are always super friendly and professional. Denise is my usual person for cleaning and makes it as enjoyable an experience as going to the dentist can be. 10-10 would recommend and always do for anyone I know that needs good care.
This dental office is by far THE BEST I’ve ever been. The entire staff is fantastic! Lonnie, Teri Dr. Steve, and Dr. Jim especially make my teeth and my visit perfect!
This is the only place i will go to the Dentist. I am a huge chicken when it comes to the dentist, but everyone is so friendly and Steven M. Chichetti, DDS is very reassuring and makes it very comfortable. Robert H. Friedman, DMD is also very good. The front desk staff is the best
Denise, my hygenist does an excellent job always.
I have always had a great visit. Love the staff, everyone is so caring.
Always great care Only place to get your dental needs taken care of.
I always have an excellent experience at Ramapo Dental Care. They make me feel at home and we all know that is hard to do at a dentist office. I constantly look forward to my next visit and no longer fear or dread dentist appointments.
I had a great experience here. I am not a fan of the dentist at all but once I walked in the staff was so polite. I had to get my crown put back on and they were able to put it back with no pain at all. I would highly recommend this place.
My whole family has gone to Ramapo Dental in Suffern, NY for more than 2 decades… We love it their, the level of professionalism and customer service surpasses our expectations with every visit. We love Carol, she is the best!!!
Professional and friendly staff! Dr. Steven Chichetti is a gem
The best dental care you will find anywhere, together with the nicest people.
Thank you for taking care to my situation as a forener. Thank you for the service & explanation about what I have to do next.
I had called as a new patient with a tooth problem. They had no problem accepting me the next day without hesatation. My visit was terrific with my tooth problem being solved very quickly. As a result I have become a new patient of Ramapo Dental Care.
Lonnie and the frost desk are simply the best!
Great place! Love it!
Ramapo Dental has a terrific staff at the front and I am always pleased with the care and treatment that I get there. They are very thorough and on time and caring. I am glad that they are my dentists.
It was the best dental experience I’ve ever had.
All of the staff are very friendly and welcoming, and at the same time very professional and organized. Coming here is always a pleasant experience, and I always leave knowing my teeth are in good care!
Dr,.Gusmano is the best! Caring, professional and expert.
Very professional and the cleanest dental place I have ever been
Consistently caring and through service. No long waits in the waiting room, pleasant and effective.
Great dentists and staff members all so friendly! Do a great job cleaning teeth!
I’ve been going here for about ten years now. Always a pleasant experience. Carol is the best! I always make sure to schedule my semiannual cleanings with her!
Great staff and dentists! Satisfied with how clean my teeth are now!
Great dentists and the cleanings are thorough
Staff was very nice made me feel comfortable
I’ve been gong to this dentist for 12+years. The staff are super friendly and professional. Family oriented and long term carer. Highly recommended.
always a great experience when I am there – from the front desk, to the girls who help Dr. Chichetti and of course Dr. Chichetti himself..
Very friendly professional staff. Everyone I know goes there.
My family has been coming here for years. Great staff excellent doctors!! Thank you Ramapo Dental you guys are awesome!!!
Absolutely fantastic dentists and staff. I used to be so afraid to go to the dentist, now it’s a breeze, wish I knew about these guys when I was a lot younger.
Dr Chichetti and his staff are wonderful. After not seeing a dentist in 10+ all the staff at Ramapo Dental Care made me feel comfortable and at ease from the moment I walked through the door. Every visit the staff takes time to answer all my questions, no matter how silly and takes the time to explain each procedure to me,making me feel completely comfortable and informed. I would highly recommend…
Carol is the reason my family comes to Ramapo Dental!! She is simply the best. She is professional, friendly and caring. Unfortunately my opinion is not the same for the dentist I saw. The dentist came in the room asked 2 questions, poked around my teeth for 30 seconds and left the room. My review is for Carol only!!!
The best dental office I’ve ever seen. Dr. Guzmano and Claire made me believe I might die with my own teeth (hopefully, that’s a long term prediction). Office stuff is very friendly and professional. I wholeheartedly recommend this office and people.
I love ramapo dental. They are professional, down to earth, friendly & very skilled. Love the whole staff, especially my bud Denise! My whole family comes here for the best pain free care.
I have been going to Ramapo Dental since I was a child. They are absolutely wonderful. I recently had a routine cleaning done by Denise and examined by Dr. Gusmano. They are always so personable and professional as well as the rest of the staff. I look forward to bringing my son when he gets older. Highly recommend.
My family has been seeing Dr. Gusmano at this practice for over 20 years. He is great, and the hygienists and office staff are always very pleasant, helpful, and professional. It’s nice to go to a medical office where everyone is friendly and remembers your name. Highly recommended!
Dr. Steve is one of a kind. He takes the time to sit with you and give you full details on the state of your mouth. It’s nice to be able to trust someone in the industry. The secretaries up front are very friendly and make you feel welcome the second you walk in the door. Thanks Ramapo Dental!
Great dental experience with Dr Chichetti! Professional, warm, friendly and caring dentist & staff. I would highly recommend Dr Chichetti!
I visited the office today for a cleaning and was blown away with the professionalism and efficiency that the staff as a whole displayed. Robin at the front desk greeting me with a warm welcome and Claire gave me a thorough and fast cleaning. I would recommend this office to anyone who wants to deal with a skilled and knowledgable staff. Fantastic service. A++
Timely, competent and caring…all describe the care received at Ramapo Dental Care. Reception, no matter who you speak with, is right on the ball and very helpful. My teeth will have none other than Dr. Chichetti and Carol caring for them as they have done for many years. I am 76 and never lost a tooth yet. That should testify to excellent dental care.
My visits to Ramapo Dental Care are always excellent, and this was no exception. Not that I like going to the dentist, but Carol does an excellent job of cleaning my teeth. I am very fussy about this, never having had a cavity but being told long ago that improper dental hygiene could nevertheless cause the loss of my teeth. Carol is friendly and efficient, and I trust her judgment completely. Dr.…
Everyone is professional, but they make you feel as if you are a member of their family. The quality of dental care is excellent and I have never been in doubt of the treatment I’ve received.
My family has been going to Ramapo Dental for many years now. I have always been extremely satisfied with the dental work we have received. The staff is always friendly and courteous. They are very accomodating to any changes in appointments. The administrative service is also wonderful with handling invoices/bills/insurance. I thank them all, and will be continuing my dental service with them for…
I have been going to Ramapo Dental Care since I moved here in 2005, and I’ve been very happy with the care I’ve received. They never try to force treatments on me, preferring instead to look at my health as a whole. For instance, I have had numerous skin cancers on my face but never a cavity. X-rays are never pushed, but I am always asked. Our joint decision has been to skip them for n…
