About a year ago, Dr. Sewall removed an oral tumor from my jaw. He explained everything thoroughly and made sure that I understood the entire process. I felt as though he made decisions with my best interest in mind. I also like the way he interacted with his students and allowed them to learn from their experience with me. I had very little pain, despite the removal of this tumor, loss of teeth, and bone graft from my hip. He was phenomenal with my insurance company, who was giving us the runaround, and was vital in helping us secure coverage for the procedure.
