Dr. Ronald Cooper began his interest in dentistry in high school as part of an externship program which involved visiting with and learning from a local dentist. After that experience, he began volunteering and assisting dentists through college. Dentistry was a career path that seemed to match his natural inclination for fixing things. And today, when hes not fixing smiles, hes often fixing up his home in Potomac. Dr. Cooper grew up in Long Island and finished high school in Maryland. After two years at Franklin and Marshall College in Pennsylvania, he transferred to the University of Maryland where he received his undergraduate degree in biochemistry. He went on to acquire his DDS, with honors, from the University of Maryland Dental School in 1988. From there Dr. Cooper continued his dental education with advanced training in post-graduate general dentistry at Emory University in Atlanta, Georgia. While there, he served the community by volunteering time to those in need in Grady Hospital. Dr. Coopers dental education continued with the acceptance of the Fellowship award in General Dentistry in 1997. He then became more focused on preserving teeth while at the same time improving smiles. Dr. Cooper is a member of several national and local professional associations including the Academy of General Dentistry, the American Dental Association and the DC Dental Society. Along with home renovations and home automation, Dr. Cooper enjoys woodworking and spending time with his family. He and his wife Lesley, an attorney, have three children.

During every visit, we will share with you everything you should know about your dental condition as well as new technology and services. We want to educate you so you will feel comfortable making decisions about your dental health.

From a very early age, Tran always enjoyed going to the dentist. She appreciated the education she received about oral hygiene, the interactions she had, and the relationships she built, with the dentist and staff. Tran was inspired to help others and knew that, one day, she would enter the field of dentistry to provide the same educational and compassionate dental care she had experienced in her own life. Born in Vietnam, Tran was exposed to many different cultures and environments. Relocating to the United States, Tran settled in California, then moved to Kansas, Maryland, and finally Washington D.C. making her adaptable and conversant with people from many different cultures and backgrounds. As Tran laid out her plans to pursue a dental hygiene career, her move to Maryland allowed her to complete her education with a Bachelor of Science Degree in Dental Hygiene from the University of Maryland Baltimore Campus, College of Dental Surgery Dental School. Upon completion of her degree, she was chosen to be part of the Dental Hygiene Admissions Committee, where she spent many hours assisting the committee in selecting new students. Concurrently, she worked at the Greenbaum Cancer Center and The PLUS Clinic in Baltimore, providing comprehensive dental care and educational services for immune and medically compromised patients. Tran is meticulous and diligent in her work and takes pride in delivering excellent oral healthcare to every patient. Tran is passionate about her work and has devoted herself to motivating and educating her patients to achieve a lifetime of optimal oral health.

The front desk staff are very helpful and personable. I arrived early and was seen early. My dental technician, Marisa, is highly skilled in her cleaning technique and Dr. Phillips always explains everything so well. It's a pleasant experience to get my dental cleanings here.

I've been a patient at Dr. Coopers office for about 3 years now I believe and it's one of the best decisions I've made regarding my overall heath and wellness. Always friendly, always helpful and and always resourceful when it comes to what's going on with your dental hygiene. Most places won't even elaborate on how your teeth are doing. Just get in there do some work and keep it going but Dr. Cooper and his staff always break down exactly what's done, why its being done and how it got to that point. And I like that...now if you'd excuse me I have to go floss. 5 "that's ights" outta 5

"Been going to Dr. Cooper for several years, highly recommend him. He and his staff are very helpful and professional, always a good experience." That sentence was posted more than a year ago I think, and still true. Great office, always efficient and helpful, great hygienists and reception staff. I moved about an hour away from DC 2 years ago but still drive in when I need an appointment, rather than change dentists. - Feb 2022

I went to see Dr. Cooper yesterday. He was very attentive, helpful and pleasant. He's very knowledgeable and took the time to explain what was happening to my teeth. After two years of suspecting that my former dentist wasn't being honest with me, Dr Cooper quickly detailed possible causes on a big screen. I was finally able to comprehend my situation. I was now in good hands. Dr. Cooper discussed different ways to treat my issue. He made a plan for me. I appreciate his candor, and the way he communicates. He's at ease in his office and his style is complemented by his kind staff and smoothly run practice. Highly recommend.

No one likes going to the dentist, that is of course if you have to go to Dr. Cooper and Associates. I actually look forward to my visits, Dr. Cooper is always straight up with me and my decision to have any suggested work done is on me and no one else. I've had referrals for outside work which has also been amazing. So even the other professionals that his practice has to work with are also true to their profession. Lastly, Tran is the best. We talk about so many things during my visit and she knows my family and remembers everything that I share with her. It's the best and I always refer anyone I know who needs dental care to this office. Such a fabulous team of people!

As this was my first dental experience in over a year (COVID-19), my teeth were in a sorry state. Dr. Cooper did a thorough job of analyzing what needs to be done, Lillibeth was lovely and totally competent, and Tran did a great job scraping and cleaning off my teeth. My husband has more complicated problems, and Dr. Cooper has already done a crown for him (very successful) and is working on another. Terrific dental team!

Dr Cooper's practice has always been very professional, I have been going there for over 25 years, now. Post pandemic, I visited again and find that the doctor and his staff are very careful and always provide balanced advice and reocmmendations on how to keep a healthy mouth. In these times, its particulary difficult for all to navigate the changing safety requirements, but, they are doing a great job.
