JanJan Winter Clark

Chief Executive Officer

Jan Winter Clark is the CEO and co-owner of three hospitals serving Northeast Oklahoma: Bristow Endeavor Healthcare in Bristow, Cimarron Healthcare Center in Cushing, and the Center for Orthopaedic Reconstruction and Excellence (CORE) in Jenks.

Jan has worked extensively in the healthcare field as a direct patient care provider and in various hospital administrative capacities for more than 23 years.

Having started as a registered nurse in the emergency department, Jan climbed the administrative ranks to become one of only a handful of female hospital CEOs in Oklahoma.

Instead of idly watching rural hospital closings continue to increase across the country, Jan pioneered an innovative healthcare model to keep the doors of Bristow Endeavor Healthcare open. With the most recent addition of CORE in July 2015, Jan believes this new, diversified approach is the answer to long-term survival of rural healthcare in Oklahoma.

Jan has four children. In her spare time she enjoys attending sporting events, music concerts, reading, visiting with friends and working cattle on her Bristow family farm.
