Meet Our Team | Sleep & TMJ Therapy

Our trusted TMJ Specialist & Sleep Apnea Dentist in Falls Church, VA, near Washington D.C.
Dr. Brown grew up in Maine and attended Bowdoin College, graduating magna cum laude in 1982. He earned an early decision acceptance to the Georgetown University School of Dentistry and graduated in 1986. While at Georgetown, Dr. Brown assisted the neurology department on a research project studying nerve tissue regeneration in the spinal column following major trauma.

Upon graduating, Dr. Brown briefly worked as an associate at another dental practice in Falls Church. He then established his own practice in Arlington’s Fairlington neighborhood, growing it into one of the largest on the East Coast.

Following a brief sabbatical to help raise his four young children and advance his education, Dr. Brown began deeply studying sleep apnea and its correlation to TMJ disorders. His advanced understanding of the interconnected fields of TMJ, sleep and orthodontics provides a comprehensive perspective that sets him apart from traditional general practitioners.

He also mastered advanced airway expansion techniques to improve breathing in both children and adults. He continued his specialized training at the renowned Sleep Center near Emory University Hospital. Dr. Brown is a certified Fellow of the American Academy of Craniofacial Pain, holds Legacy status with the ALF Interface Academy, and is an active member of numerous other professional organizations.

Karina is our lead assistant and manages all lab cases here at Sleep & TMJ Therapy. She started working with Dr. Brendan Stack in 2008, gaining invaluable experience in the specialized fields of TMJ, sleep apnea, and orthodontics. Honored to have observed and learned from his work over the years, Karina is dedicated to sharing this advanced knowledge with both our team and our patients.

While working, Karina attended ECPI University, where she earned her Associate Degree in Health Sciences. Over the years, she has developed an exceptional clinical and patient-relations skill set, enabling our doctors to help countless patients live pain-free lives. Looking ahead, she hopes to return to school to further her education in the dental field. Outside the office, Karina loves spending quality time with her two sons and daughter.

Tamyra is a Virginia native and a valued member of our clinical team who studied at the Metropolitan Institute of Health and Technology. She has been working in the dental field for 10 years and absolutely loves it. Because TMJ specialty offices are rare, we were ecstatic to find someone with her extensive experience in temporomandibular joint dysfunction (TMD).

Outside of work, Tamyra is a proud mom to four beautiful children—three girls and one boy. Her ultimate goal is to give her kids the most out of life and be the best mom she can be. She looks forward to meeting you all!

She graduated from Northern Virginia Community College and earned her massage therapy license from the Potomac Massage Training Institute.

Ruth is originally from Mexico, but she has made the U.S. her home for 30 years. When she’s not working, she enjoys traveling, dancing, attending cultural events, and exploring new culinary experiences.
