Patient Success Stories

San Ramon Valley Dentistry is amazing. The staff is kind, professional, and knowledgeable. They are always on time when I arrive for my appointments. They provide cutting edge practices for dentistry and orthodontic in one location.

I am very content with San Ramon Valley Dentistry! Dr. Nico treats his patients with much consideration and professionalism. He is very attentive to your case and gives you a clear explanation of the treatment needed. Dr. Nico’s staff is excellent. You’d be hard pressed to find RDAs as nice as Claudia and Yadi. I went for a cleaning and Bessie the hygienist was so friendly and attentive and did an excellent job. I’d highly recommend San Ramon Valley Dentistry to anyone.

I have been going to San Ramon valley Dentistry since Dr Nikolas took over the practice from Dr Grasso Dr Niko and staff really made it a smooth transition, It is a state of the art office with all the new and latest dental equipment , very clean and comfortable. Dr Niko has a incredibly soft touch when performing his work, Always asks how you feel etc. His staff is excellent in every way. Claudia his assistant , Bessie the hygienist are tops at their profession. there is also another lady named Claudia who runs billing and the front area. There is also a new lady named Julia that also helps up front , looks like she will fit in there just fine. I will give a shout out too Dr Nikos wife for the decorating of the office, I’m pretty sure it was her , It really has the lady’s touch. To all if you are looking for a dentist, Please give them a try , you won’t be disappointed.

I am not named Taco the Cat; Taco was my cat and I love him so I named my Gmail account after him. I you want to know, my name is Anna and I’m here to tell YOU why you should get your teeth cleaned at San Ramon Valley Dentistry. I have been going to San Ramon Valley Dentistry since it was in Dublin under the previous practitioner. It’s quite obvious that Dr. Niko is a big teeth nerd and is very enthusiastic about helping his patients have straight and healthy smiles. The staff are also consistently nice and professional. The dental assistant that I usually see, I think her name is Bessie, is really fantastic. Not only is she great at cleaning teeth, but she is also a genuinely caring and friendly person. My teeth always feel so refreshing and clean afterwards, and she is super careful about not hurting my gums. Ask for her if you get the chance, I want her to be busy as heck and for the whole greater East Bay to experience the sensation of squeaky clean chompers. And if you see this Dr. Niko, give her a raise- I’ll be asking about it on my next visit lol.

Taco The Cat

Just had my first visit with San Ramon Valley Dentistry today and was pleasantly impressed. I was referred to Dr. Niko by my previous Dentist who recently retired and being one who doesn’t always embrace change, I was a bit skeptical. When I arrived I was greeted by friendly staff, a very clean and safe environment with much better technology that I was accustomed to. Great overall and I will definitely stay the course with them!!

Dr Grasso has been my dentist since 1994 when I lived in Dublin. I moved to Sacramento in 2000 but I continue to drive to San Ramon for Dr. Grasso to take care of my dental implant needs. His chairside manner is excellent, his hands are light and gentle, he patiently explains procedures to me and answers questions in a way that I understand. His Office Manager runs the office efficiently, takes care of my insurance claims, explains my bill in relation to my procedures and patiently answers any questions I might have. His staff is always professional, warm and welcoming. I would never go to a different dental practice.

I'm always treated with the greatest courtesy and friendliness. Dr. Niko has an outstanding staff that show genuine care for the patient. I highly recommend San Ramon Valley Dentistry.

José Z.

I'm very happy with the care I've received at San Ramon Valley Dentistry and I highly recommend Dr. Niko. I've known Dr. Niko for many years and have been a patient of his since he moved into this area several years ago. I have a history of complicated dental work and Dr. Niko has always gone above and beyond to address and fix my problems and ensure that I have a good understanding of what is happening and my options. What's best, I've not had any problems at all with the few larger pieces of work he's done for me. In addition, his staff is super friendly and professional, and I've always been treated the absolute best. Thank you Dr. Niko and staff, my family and I are glad to have you as our family dentist.
