Todd E. Grigereit, Ph.D.

Director of Medical Physics, Alliance Oncology

Todd E. Grigereit, Ph.D. is the Senior Medical Physicist at Alliance Cancer Care Colorado at Red Rocks and has been with the center since May 2011. He is also the Director of Medical Physics for Alliance Oncology.

He received his Bachelor of Science from Purdue University in West Lafayette, Indiana, his Master’s Degree from Washington State University in Pullman, Washington, and his Ph.D. in physics from Montana State University in Bozeman, Montana. He spent two years at the National Institute of Standards as a research scientist and assistant professor at the University of Maryland Superconductivity Center, working primarily with neutron scattering properties of superconducting and magnetic materials.

Dr. Grigereit’s clinical experience in medical physics began in Bethesda, Maryland, at the National Naval Medical Center, Uniformed Services University, and the National Cancer Institute, where he worked as a clinical medical physicist, assistant professor of radiology, and senior staff fellow. At Mallinckrodt Institute of Radiology, Washington University School of Medicine, and Barnes-Jewish Hospital in St. Louis, he expanded his clinical and research experience working with many of the most recent developments in radiation therapy.

In his role as Senior Medical Physicist, safety and accuracy are his primary missions as he helps the radiation oncologist to manage all aspects of radiation planning and delivery for cancer patients. This includes commissioning and calibration of all delivery and computerized dosimetry planning systems, as well as the rapidly evolving, specialized imaging and measurement tools.

Dr. Grigereit has written over 40 peer-reviewed articles that have appeared in national physics and medical physics journals and is certified by the American Board of Radiology in Therapeutic Radiological Physics.

When he is not helping patients, Dr. Grigereit is totally devoted to his family. He and his wife worked together to homeschool their five children and he shares many interests with his family including a lifetime love of learning, outdoor activities such as hiking and camping, and competitive swimming.
