Get to Know

Dr. Williamson

Growing up in Belleville, IL, Dr. Williamson admired his family dentist and knew that one day he would work in the medical field. He graduated from Illinois Wesleyan University with his Bachelor of Arts in mathematics. He then went on to attend dental school at Southern Illinois School of Dental Medicine, where he received his Doctorate of Dental Medicine. 

Upon completing his education, Dr. Williamson began practicing at a family dental office in St. Charles, IL where he gained valuable knowledge and experience. When he moved to Missouri, he started practicing with Dr. Raney. When Dr. Raney was ready to pass the torch and take a step back, Dr. Williamson was honored to fill his mentor’s shoes.  

Dr. Williamson loves dentistry because he is able to work with his hands while combining his passions for both science and art. He enjoys making a real difference in his patients’ lives and is grateful to own his own practices in Festus and Columbia. Outside of the office, Dr. Williamson can be found attending sporting events, playing music, and playing board games with his wife and three kids.
