I find all the employees at Greenbelt Dental Associates to be wonderfully warm, friendly and knowledgeable. Lydia is a wonderful at keeping track of appointments and billings. Alice is the most outstanding dental hygienist I have ever seen! She does extremely detailed, caring and painless work and makes my teeth feel like new. Dr. Galvan and Sandra have done superb, thorough work on my teeth and kept them in wonderful condition! I feel very blessed to have the employees at Greenbelt Dental Associates taking care of my dental needs.
Review from Sarah


My experience at Greenbelt Dental Associates is the absolute best. I have been going there for over 20 years, first with Dr. Allen (now retired), and now with Dr. Emma Galvan and Dr. Karl Meek. You will not be disappointed. They both are experienced dentists who know their business, and they insist on only the best standards in the office. I referred a friend recently who had some major dental issues, and my friend is very pleased with the services she is getting in this office. In addition, all the staff members are incredible. Lydia is the first person you will meet, and she handles scheduling and accounts with a smile and flexibility. Sandra is a dental assistant who will treat you kindly and with professionalism. Alice is the dental hygienist who has cleaned my teeth well for all these years.
