William I. Roth, MD, is a board-certified dermatologist who has been in practice for 34 years. His conviction in the superiority of superficial radiation therapy (SRT) for skin cancer treatment dates back to his joint practice with Victor H. Witten, MD—and Witten’s work with his past partner, Marion Sultzberger, MD. Dr. Roth continues the legacy and breakthrough science of their innovations. Dr. Witten and Dr. Roth worked together demonstrating SRT excellent results for almost 15 years in Miami. The availability of new, safer and improved SRT delivery systems from Sensus Healthcare now helps Dr. Roth provide SRT in his private practice in Boynton Beach, Florida. Dr. Roth is a clinical professor in The University of Miami School of Medicine Department of Dermatology, a Fellow of the American Academy of Dermatology and a member of the American Medical Association.
