Two veteran health care administrators with wide-ranging experience have assumed key leadership roles with NorthBay Healthcare.

Wayne Gietz, who for the last five years guided NorthBay’s outpatient services, is the new president of NorthBay Healthcare Group. He succeeds Aimee Brewer, who is the new president and CEO of Sturdy Health in Massachusetts.

Gietz has an accomplished track record in health care executive management. Prior to joining NorthBay, he held executive leadership roles in two New York City-based health systems. In his new role he will oversee NorthBay Medical Center in Fairfield and NorthBay VacaValley Hospital in Vacaville, all ambulatory services and NorthBay Medical Group, the collection of 100-plus physicians and providers.

Following a nationwide search, Tracy Geddis has become vice president of operations, taking over for Nicole Brocato. A veteran of Sutter Health for more than 20 years, Geddis most recently served as associate administrator of Sutter Solano Medical Center in Vallejo. While she is new to NorthBay, she is quite familiar with the community. 

Geddis has served on the boards of directors of the Solano Coalition for Better Health and Vallejo Chamber of Commerce. She successfully co-chaired Solano’s March for Babies, the March of Dimes fundraiser. She is a graduate of UC Davis.

Meanwhile, Chief Medical Officer Dr. Seth Kaufman, M.D., will join NorthBay’s senior management team, assuming overall responsibility for quality, patient safety, licensing and accreditations and social services. An emergency medicine physician, he has been affiliated with NorthBay since 2005, and was named chief medical officer in 2017.
