We like to thank Dr. Bullock and his staff at The Dental Group for the fantastic job of restoring my smile. The task of installing teeth on my six implants was a difficult one. But from the beginning, Dr. Bullock had an understanding and a plan to get the job done. He was a able to explain to me so that I could understand what he was doing and answered all my questions. While he was performing his procedure on me, he and his staff made sure I was comfortable as possible. I would recommend Dr. Bullock and the staff at The Dental Group to anyone who needs special dental care. May Dr. Bullock and his staff be Blessed Always. Nannie Colbert

It was very hard for me to trust a dentist until I found Dr. Nathaniel Bullock. He made me feel relaxed and explained step by step the procedures that I needed to have a smile again. The whole team, front desk, billing specialist, his dental assistance ALL contribute to a very successful practice. The Dental Group on Baltimore Ave is my number one and only choice to have my teeth worked on. I am looking forward to smiling again. Thank you Dr. Bullock for the pride and passion that you have in your profession. You are AWESOME! I will send a pic when the work is completed.

The staff and other members at the Dental Group are courteous and flexible. They answer questions in an expedient and competent manner. The DDS that I see is professional astute to feelings of his patients and personable. His assistant is equally as competent, courteous professional and knowledgeable of the work to be completed. I am no longer afraid to go to the dentist. I recommend to colleagues and I was able to get my Mom in for much needed dental work. The Dental Group exceeds my expectations and I highly recommend their services.

I have been a patient at The Dental Group for many years. It is a warm and professional environment where the staff always greets me with a smile. I don't feel like I'm just another patient here; they let me know that they remember me and that really matters while they are either cleaning, pulling, or examining my teeth and gums: If you need dental care, I highly recommend The Dental Group!

Needed a crown replacement. I'm in DC for several months. I checked ratings online and called for an appointment. They were able to offer me an appointment right away. The online process of filling out patient information was easy. When I checked in my paperwork was there; the front desk was very efficient. After waiting a very few minutes. The dental associate took me back. She was very professional and gentle, putting me at ease straight away. Dr. Tajick was very thorough and talked through each step she was taking. The dental tech working on my temporary crown took many steps to insure i was satisfied with the level of work. I would recommend this teams services without hesitation.
