Patients Are Saying…



Jill B.

Im so glad my husband and I found BDD. Dr. Johnson and her entire team are outstanding and make you feel comfortable from the moment you walk in the door. The hygienists take their time, perform a thorough cleaning, and focus on patient education.

As a nurse, I would not trust anyone else with my care. I feel empowered in taking control of my own health- not just to my mouth, but my entire body, due to their integrative approach to dentistry.

Annie R.

First of all the Brentwood Dental Designs office is impeccably clean, warm and welcoming. It is a state of the art dental office without a doubt.
