Clinical leader Doug Diehl, MD, to retire
Doug Diehl, MD, vice president of Provider Engagement and Wellness for APP, has announced his retirement. His final day with Asante will be Aug. 2.
Dr. Diehl has served in a number of leadership roles, including chief medical officer of APP and vice president of the specialty care group. He is known as an approachable leader with a quick sense of humor and a full embrace of APP’s Hawaiian Shirt Friday.
He joined APP in 2014 after working as an anesthesiologist with Asante Ashland Community Hospital and serving as that department’s medical director.
Dr. Diehl earned his medical degree from Cornell University Medical College in New York. He completed his internship in internal medicine at University of New Mexico Hospitals and residency in anesthesiology at the University of California, San Diego.

Before coming to Ashland, Dr. Diehl headed the anesthesiology department at Memorial Medical Center in Modesto, California, where he also served on the board of the Memorial Hospitals Association.
At Asante, Dr. Diehl served as a physician leader, helping to guide APP’s rapid rise from a startup to an organization with more than 300 providers and 40 clinics in locations from Ashland to Grants Pass. Besides expanding APP’s market presence, Dr. Diehl helped lead Asante’s effort to adopt new care models based on population health principles.
During his tenure, he gained a reputation for building relationships with his teams and recognizing individuals for their contributions. “I believe there is strength and synergy in strong, well-functioning teams, and that a rising tide lifts all boats,” he said of his leadership philosophy.
Most recently his work has focused on promoting provider well-being to increase job satisfaction and retention. He has been active in the community, serving on the boards of the Britt Festival and the Hearts and Vines Foundation.
“I would like to thank him for his contributions to APP, including in the areas of recruitment and retention of physicians, provider well-being and network development, along with his contributions to AACH during his time as chief of staff,” said Jamie Grebosky, MD, chief medical and quality officer. “Please join me in wishing him the best in his retirement and thanking him for his leadership and years of service.”
Provider wellness activities will be managed by Barry Egener, MD.
