Dr. Horia Vulpe MD, CM

I am a radiation oncologist specialized in the management of malignant and benign tumors with radiotherapy and radiosurgery. I believe that each patient deserves access to a knowledgeable team of experts, wherever in the world they may be.

Together, we are stronger in our fight against cancer.

About Me

My career has spanned leading institutions like the Princess Margaret Cancer Centre in Toronto and Columbia University in New York, where I developed and refined cancer treatment techniques. I currently practice with Kaiser Permanente Medical Group in California.

Beyond clinical practice, I am deeply committed to research, education, and improving cancer care through international collaborations.

Cancer Care Program for Ukrainian Refugees

At the onset of the war in Ukraine, I led a humanitarian cancer program with the Blue Heron Foundation that centered on Ukrainian refugees in Romania and Moldova. Through our efforts, we provided life-saving treatments to over 170 Ukrainian cancer patients in the region.
