Dr. Sharpe continued this effort at scale by serving as the Quality Leader of Cancer Care Ontario's Radiation Treatment Program. His animated and engaging teaching skills were sought after by many. He delivered lectures on advanced radiotherapy techniques to medical physicists, radiation oncologists, and radiation therapists in local courses and at invited lectures around the world. He was recruited by the American Society of Radiation Oncology (ASTRO) for their international teaching programs and in 2011, was a founding faculty member of the annual European Society of Radiotherapy and Oncology (ESTRO) course on Advanced Treatment Planning.
