Stanley “Skip” Rosenthal, Ph.D.

Senior Vice President, Clinical Affairs

Skip's thirty years of radiation oncology and proton therapy experience began at the Harvard Cyclotron Laboratory in 1991. While working there until it closed in 2002 and at Massachusetts General Hospital (MGH) until 2005, Skip’s work included the creation of novel treatment planning and patient positioning for particle therapy. He served on the MGH leadership team that oversaw the installation and operation of the world’s first commercial proton facility, the Northeast Proton Therapy Center (now named the Burr Proton Therapy Center) at MGH. Skip led their medical physics program and invented a computerized digital imaging system for patient setup. With CMS (now Elekta), he developed and commissioned the first commercial treatment planning system for proton therapy and has provided consultation for the proton centers at Indiana University and Loma Linda University.

Skip joined Mevion in 2005 and is the senior advisor for the next generation of clinical systems and customer success. He created and leads Mevion's customer education, training and user programs and has trained hundreds of physicians and physicists in the art and science of proton therapy.

He has held an assistant professorship at Harvard Medical School and appointments at the Massachusetts Institute of Technology (MIT), Boston University Medical School, and University of Massachusetts Medical School. Skip holds a BS in Physics and Mathematics from Brooklyn College CUNY, a Master’s of Science, and a Ph.D. in Physics from Brandeis University. He is board-certified in therapeutic radiologic physics, a well-published clinical author, and over his career, has contributed to the treatment of over 10,000 patients.
