The Team

Dr. Jeffrey L. Brown

Dr. Jeffrey L. Brown grew up in the state of Maine and went to Bowdoin College, where he graduated magna cum laude in 1982. He accepted an early decision acceptance into the Georgetown School of Dentistry and graduated from there in 1986. While at Georgetown, Dr. Brown worked in the neurology department as an assistant on a project that involved studying the regeneration of nerve tissue in the spinal column after major trauma.

Upon graduation from Georgetown Dental School, Dr. Brown worked for a short time as an associate in a practice in Falls Church, Virginia. From there, he moved on and built his own practice in the Fairlington neighborhood in Arlington, Virginia, creating one of the largest practices ever seen on the East Coast.

Dr. Brown took a short sabbatical to help raise his four young children and to continue his education. It was then that he began the process of understanding sleep apnea and how it correlates to TMJ treatment. His knowledge in the combined fields of TMJ, sleep and orthodontics has given him a perspective unlike most other practitioners who perform basic dentistry. In addition, Dr. Brown has also learned the advanced techniques involved in expanding an airway so that both children and adults can breathe better. His training continued over time at the famous Sleep Center near the Emory University Hospital. He is a certified Fellow of the American Academy of Craniofacial Pain, was awarded the level of Legacy with the ALF Interface Academy and holds memberships with many other academies.

Tamyra is a member of our clinical team who studied at the Metropolitan Institute of Health and Technology and is a Virginia native. She has been working in the dental field for 10 years and absolutely loves it. As you may know, there are few TMJ specialty offices around, so we were ecstatic that Tamyra has previous experience in the field of temporomandibular joint dysfunction (TMD). She has four beautiful children, three girls and one boy. Her goal is to give her kids the most out of life and to be the best mom she can be. She looks forward to meeting you all!
