Meet Dr. Mark Geller

I have been in practice for more than 40 years, and continue to be energized by the opportunity to create great smiles, healthy and comfortable bites, and to provide encouragement to both young and older patients as they face many different kinds of life’s challenges. My ultimate goal is to deliver excellence beyond patients’ expectations and educate patients in the value of oral healthcare and the importance of a comprehensive treatment approach that goes beyond just delivering straight teeth. 

I am very fortunate that my life led me to dentistry and ultimately orthodontics. Each patient is unique and I enjoy hearing their stories, finding out about their wants and desires, and helping them achieve their goals in a fun and caring environment. 

I am gratified when I uncover a concern the patient was not even aware of and, when addressed, they appreciate how much more comfortable and better they feel. Every day I’m challenged, and every day I am learning and striving to perform at a higher level. I continue to be energized and motivated and look forward to each new day.

Education and Experience

I attended the University of Oklahoma, graduating with a Bachelor of Arts degree in History. I completed my dental and orthodontic training at Baylor College of Dentistry, earning my Doctorate of Dental Surgery and Master of Science in Dentistry in Orthodontics.

The exciting aspect of providing orthodontic treatment is delivering care that hopefully exceeds the expectations of my patients. Continuing education exposes me to the latest innovations and procedures that can further aid the attainment of excellence. My team and I subscribe to the adage that we attempt each day to achieve even better care for our patients than the day before.

I participate 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 was an adjunct assistant professor in the Department of Orthodontics at Baylor College of Dentistry for 25 years.

Family and Community

I was born in St. Louis, Missouri, and raised primarily in Oklahoma City, Oklahoma. I have lived in the Dallas, Texas area since 1969.

My wife Madeleine and I have three wonderful, successful daughters who have provided us with nine super grandchildren. We are a very close family and we all communicate almost daily. We love to take trips together, though it is more difficult these days as the grandchildren are involved in so many activities. We all love the beach and the mountains, and everyone is athletic so we all make exercise a routine part of our lives. I have been a tennis player and runner for most of my life, but somewhat recently have allowed golf to take over.

The Rotary Club of Plano and Rotary International has been one of the many organizations I've worked with that is most impressive. Rotary is the oldest of the service organizations and impacts local, national, and international causes well beyond what most people appreciate. Rotary has taken a major role in eliminating Polio worldwide. They help with water projects in third world countries, provide shelter supplies when disasters strike, and provide youth and business exchanges to enhance understanding and peace throughout the world. One of my local clubs most significant projects was building a children's medical care clinic for underprivileged families. I consider it an honor to be a part of such important work.
