Meet the Four Dentists at R+R Dental
Dr. Michael Richer, Co-Founder
Dr. Richer grew up in Farmingdale and lives in Bethpage with his family. He earned his D.D.S. at the University of Toronto, is a member of the Academy of General Dentistry, and trains regularly in cosmetic dentistry, Invisalign, and CEREC crowns. Away from the office, you’ll find him mountain biking or backpacking. Meet Dr. Richer
Dr. Nadia Rivera, Co-Founder
Dr. Rivera was born in Spain and raised in Puerto Rico. She earned her biology degree and her D.M.D. at the University of Puerto Rico, then completed her general practice residency at Montefiore Medical Center. She’s an Invisalign provider, keeps up with new techniques through study clubs and seminars, and speaks English and Spanish fluently. Away from the office, she loves to bake and travel. Meet Dr. Rivera
Dr. Rebecca Vaglica and Dr. Kiran Sharma
Both earned their dental degrees at Stony Brook, completed general practice residencies, and worked in private practice before joining R+R Dental in 2026. Dr. Vaglica grew up in Bellmore and always takes time to explain your treatment options. Dr. Sharma was raised here in Hicksville, and her motto is one we share: “Cure sometimes, treat often, comfort always.”
“Dr. Richer and his wife are so kind and generous. They care about the patients. They make sure you feel comfortable.” —Maria K.
How R+R Dental Started in an Empty Office
Dr. Richer and Dr. Rivera met during their general practice residency at Montefiore Medical Center. After a few years in other practices, they opened R+R Dental in 2009 in an empty space with two treatment rooms, and their very first patients were family. Today our full team works toward the goal they started with: time to explain things, modern technology, and a visit that feels easier than you expected.

Many new patients start with a tour of the office.
You’ll see your X-rays and hear your options and costs first.
Blankets, neck pillows, TV or music, and laughing gas when appropriate.
“As someone who once was very nervous at the dentist, Dr. R and their practice I highly recommend to anyone who asks. I have been going to them for over 10 years. They are caring and very sensitive to the needs of their patients.” —Joanne M.
Haven’t been to the dentist in years?
It’s never too late to feel good about your dental care.
Whether it has been six months or more years than you’d like to admit, we’ll help you understand where things stand and what comes next. You’ll never get pressure or judgment from us.
I can’t explain how happy I am since I found Dr Rivera and the entire staff at R + R Dental. From check-in to check-out everyone makes you feel welcome and comfortable. Dr Rivera is a master of her craft and replaced a crown for me with nothing short of ease and perfection. I, like many, have always had a ton of anxiety about having dental work done but those fears are completely erased by Dr Rivers’s care and the friendliness, knowledge and compassion of her entire staff. I am so grateful to be in such good hands, thank you so so much!
” The hygienist who treated me relocated and she referred me to Diana. I could not have been happier. She was gentle and kind. She gave me a thorough cleaning and good dental advice. Dr Cruz is exceptional in his approach and care. Wonderful office!
” We chose R+R when moving my 16 year old son up to a non-pediatric office. The staff could not have been any more warm and inviting. Everything was explained in full detail and we felt extremely comfortable. Diana was an excellent hygienist and explained the scans and procedures to my son fully. Dr. Rivera has a wonderful manner and made us feel confident that we’ll be getting the absolute best care. I couldn’t have asked for a better first visit!
” The service was comfortable and quick, the staff were welcoming and kind. Would recommend!
” Very friendly staff. Caring and professional. They work with you and help with all your dental fears.
” R&R is by far the most professionally run dental practice with the best staff and greatest dentists So clean and modern I highly recommend them
” I cannot rave about this place enough. My dental hygienist, Taryn, was very friendly, thorough and knowledgeable. The place is clean and organized. It was my first time so they showed me around which is so nice. I even liked how they stressed the importance of sterilization and even showed their sterilization station and the organization of it. They have the most up to date machinery taking intricate and high quality pictures and x-rays. Not to mention, they even got me a gift which is the sweetest thing.
” Had a great experience with Diana and Dr. Cruz during my visit today! They were professional, kind, and made everything smooth and comfortable. Highly recommend!
” The dentist and assistant were very kind and through with my cleaning. They went through every process step by step explaining what they were doing and why. They made me feel very at ease. Would highly recommend.
