Geren assumes the role vacated by Michael Calhoun who was promoted to CEO/executive director of CMH and Citizens Memorial Health Care Foundation beginning Jan. 1, 2022.

“Tregg has extensive health care experience over his career. He has worked for us before as the chief nursing officer and did an outstanding job,” said Calhoun. “His knowledge and experience of both the clinical and operational areas of health care combined with his character, strong work ethic, and previous leadership roles including at CMH, will make him very successful as our next COO for the hospital.”

Geren received his nursing degree from St. John’s School of Nursing, a Bachelor of Science in Nursing from Missouri State University, and earned a Master of Business Administration from Webster University.

As the hospital COO, Geren will oversee the daily hospital operations and will have organizational responsibility for laboratory services, radiology, pharmacy, rehabilitation services, environmental and nutritional services, health information management, materials management, plant facilities, auxiliary, pre-hospital services and emergency management.  Additionally, he will provide administrative support for hospital-based physicians.
