About Us


Director of Interventional Oncology and Immunotherapy, Image Guided Cancer Specialist

Dr. Williams is one of the pioneers of ablation and immunotherapy. He performed the first ablation procedure to combine intra-tumoral injection of immunotherapy agents. He has performed thousands of ablation procedures. In the last few years he has been advancing the use of ablation combined with immunotherapy. He has performed many “first in human” procedures in multiple areas of ablation therapy. He is actively involved in research combining numerous different immunotherapy agents with ablation for almost all cancer types.
