Meet Our Founder Dr. William Marshall

Since 2012, I’ve been privileged to work with thousands of patients in six separate orthodontics offices. I’ve collaborated with many dentists, oral surgeons, and other specialists, all in pursuit of giving the best orthodontic care possible. Plainly stated, I love my job as a Simpsonville, SC, orthodontist and I love that each person’s teeth are a unique puzzle in need of a creative solution. Together, my team and I love going the extra mile for our patients, but more than anything, we love seeing the transformation that braces can bring in someone’s life. This transformation is not just in outward appearance, but more importantly, in confidence and self-esteem!
