Dr. Tennison graduated with honors from UTHSCSA Dental School in 1985, and then completed a two year hospital based residency in Pediatric Dentistry at UT Dental Branch in Houston.  For the last 29 years  (since early 1988), he has practiced at 2021 N. Mays St. Ste1200 in Round Rock, TX.

Dr. Tennison is a General Dentist who is also board certified in Pediatric Dentistry. He maintains a very broad based family practice, providing the typical restorative treatment, but he also offers comprehensive orthodontic treatment (braces) and hospital services for infants, toddlers, and those older patients who have special needs.

Our goal is to provide the broadest possible range of services to our patients at affordable fees, so that most treatment can be done here in our office, rather than having to refer to specialists.  Towards this end, Dr. Tennison has, over the years, spent a great deal of time in training in a variety of post-doctoral studies with various mentors and teachers. This enables him to offer services like implant surgery and wisdom tooth removal and orthodontics, services not always offered by general practice dentists.

Our practice manager, Anne Cook, is the doctor’s wife. She has very successfully filled that role for over 15 years.

Together, we pride ourselves on knowing our patients, anticipating their needs, and being accessible to them when emergencies occur.
