Dr. Mark’s dad was a dental lab technician, so he was introduced to the field of dentistry at a young age. When it came time to choose his career path, he knew he wanted to be a dentist so he could spend his days helping people stay healthy and get out of pain. He’s been a dentist near Denison for almost 30 years now, and he has loved every moment of it!
As for his studies, Dr. Mark chose to attend Grayson County College before graduating from the Baylor College of Dentistry with his dental doctorate. Throughout the years, he has prioritized continuing education and advanced training through professional organizations like the Texas Dental Association. That way, he can continue to provide the people in his treatment chair with comfortable, custom, and cutting-edge care.
On the evenings and weekends, Dr. Mark enjoys spending time with family and fishing. He also is an avid traveler and is always planning his next trip!
Just like Dr. Mark was introduced to the field of dentistry by his dad, Dr. Grant was introduced to it by him. He even worked in the office filing charts and assisting his father during his summer breaks! From a young age, he loved the balance of art and science, and he ultimately decided to become a dentist as well.
Dr. Grant graduated from Texas Christian University before pursuing his dental degree at the Baylor College of Dentistry. Since then, he has achieved two major goals: becoming a Fellow of the Academy of General Dentistry and graduating from the prestigious Kois Center. If that wasn’t impressive enough, he is also an active member of several professional organizations, including the American Dental Association and the Texas Dental Association.
Outside the office, you’ll most likely find Dr. Grant hiking, traveling, or relaxing with friends and family.
Growing up, Dr. Sumpter loved science. In fact, she loved it so much she decided to use her talent and passion in a research lab! However, she found it to be a bit lonely, and ultimately decided to pivot to dentistry after shadowing a few dentists.
Dr. Sumpter attended both Florida International University and Texas A&M Baylor College of Dentistry. Since then, she has pursued continuing education with the Academy of General Dentistry and several other professional organizations. Plus, she has completed advanced training for Level I Conscious Sedation as well! Now, she’s excited to use everything she has learned over the years to help our Denison patients get the top-tier care they deserve in a calming, welcoming environment.
Dr. Sumpter was actually born in Russia, grew up in Miami, and met her husband in Dallas! They have a son, Danny, and enjoy spending their time together going to the pool, painting in the backyard, and traveling.
Love Dr. Mark and Dr. Grant! They both do wonderful work on my teeth. They are friendly, humble Christian men. I’ve gone to them for years and won’t use any other dentists. The staff are also friendly and helpful. They love their workplace.
