Dr. Williamson loves dentistry because it allows him to work with his hands while combining his love of science and art. He enjoys making a real difference in his patients’ lives and is grateful to own his own practices as it allows him flexibility to travel and spend quality time with his family. When Dr. Raney was ready to pass the torch and take a step back, Dr. Williamson was honored to fill his mentor’s shoes.
