Flint, Mich.- McLaren Health Care has selected Justin F. Klamerus, M.D., to guide McLaren Cancer Institute as its interim president and medical director.

Klamerus will transition into the position, replacing Dr. Ray Demers, who will retire March 31, 2013, after serving more than 10 years as president and medical director.

“We’re proud to welcome Dr. Klamerus to McLaren Cancer Institute during this very exciting time,” said Phil Incarnati, president and CEO of McLaren Health Care. “His strategic leadership and clinical expertise will add to the strong foundation already in place at McLaren Cancer Institute and will help us launch new initiatives to treat cancer patients, such as the McLaren Proton Therapy Center.”

“I look forward to building on the strengths of a network of talented professionals serving cancer patients in our system,” said Dr. Klamerus. “McLaren Cancer Institute is poised to make a real difference. With the construction of the new McLaren Proton Therapy Center, we will offer enhanced radiation therapy services available nowhere else in Michigan. McLaren’s commitment to fighting cancer couldn’t be more apparent.”

As interim president and medical director, Dr. Klamerus will provide leadership and direction to the medical and administrative staff. His responsibilities also include establishing and maintaining quality care standards and metrics, overseeing continued growth of the cancer clinical trials program and ensuring exceptional patient care throughout McLaren Cancer Institute.

Dr. Klamerus is a diplomate of the American Board of Internal Medicine and is board certified in medical oncology and internal medicine. He is a member of the American College of Physician Executives, and an associate to both the American Society of Clinical Oncology and the American College of Physicians.
