Radiation oncology directors​​​​ named at Siteman

Siteman Cancer Center’s parent institutions have named two new leaders in radiation oncology.


Dan Kinzel is executive director of radiation oncology at Washington University School of Medicine. Sharon Endicott is director of radiation oncology for Barnes-Jewish Hospital.

They oversee radiation oncology operations at:

  • The S. Lee Kling Center for Proton Therapy at Washington University Medical Center;
  • Siteman Cancer Center-South County in south St. Louis County;
  • Siteman Cancer Center at Barnes-Jewish West County Hospital in Creve Coeur;
  • ​Siteman Cancer Center at Barnes-Jewish St. Peters Hospital in St. Charles County.

Endicott had been Barnes-Jewish Hospital’s interim director of radiation oncology since August. As director, she will continue to work with faculty and staff members to promote patient safety, quality assurance and performance improvement throughout the radiation oncology department.

Before she was interim director, Endicott served as technical service manager of radiation oncology at Siteman for five years.

“We have a long history of being a national and international leader in radiation oncology,” Endicott said, “and I look forward to working with my colleagues at Siteman Cancer Center, Washington University and BJC in continuing to provide world-class cancer care to our patients.”

Endicott received a bachelor’s degree in health-care leadership from the University of St. Francis in Joliet, Ill. She is a certified medical dosimetrist and a radiation therapist.​​​​

Kinzel, a director in physician practice management for 22 years, previously oversaw business operations for the Division of Cardiothoracic Surgery at Washington University.

“I’m excited to be joining the nationally and internationally recognized Department of Radiation Oncology as executive director,” he said. “I’m looking forward to working in collaboration with the team at Washington University, Siteman Cancer Center and BJC to continue the advancement of services and care in our region.”

Kinzel received a master’s degree in business administration from Saint Louis University and a bachelor’s degree in science, marketing and finance from the University of Dayton, Ohio.
