Meet Dr. Mark Geller

I enjoy creating beautiful smiles and healthy bites that build a strong foundation for oral health while also increasing each patient’s self-esteem. I also find great pleasure in the personal relationships that are formed over the course of orthodontic care. I am gratified by the number of family members I have the privilege to treat as well as children of those I treated when they were adolescents.               

My practice strives to utilize the most up-to-date technologies in a very caring, communicative, and enjoyable environment, to obtain the most optimal treatment results possible. Development of well-balanced faces with attractive teeth and healthy bites are the major goals we set for all of our patients, as well as coordinating care with other healthcare providers when a multi-disciplinary approach is indicated.


I attended the University of Oklahoma, graduating with a Bachelor of Arts degree in History. I completed my dental and orthodontic training at Texas A&M University College of Dentistry, earning my Doctorate of Dental Surgery and Certificate in Orthodontics.

I continue my education by participating in numerous courses and seminars and have attended the Roth/Williams Center for Functional Occlusion. In addition to being an active member of many professional associations, I am also a Diplomate of the American Board of Orthodontics, and have taught in the orthodontic residency program at Texas A&M University College of Dentistry since 1996.
