Tolosky, who has served as president and CEO of Baystate Health since 2004, will be succeeded by Mark A. Keroack, MD, MPH.
The Baystate Health Board of Trustees has unanimously approved the appointment of Dr. Keroack, a native of Springfield, to assume the role of president and chief executive officer of Baystate Health next year.
As an interim step, on January 1, 2014, Keroack will assume the additional title and authority of president and chief executive officer of Baystate Medical Center.
â€œIt is a great honor to be selected as the next leader of this wonderful organization,â€ said Keroack. â€œThe new healthcare world will require an unprecedented level of connectedness between nurses, doctors, and allied health professionals; between specialty and primary care providers; between those who touch our patients and those who support them; between health plan and delivery system; and across all the communities and regions that we serve.â€
â€œI am excited to continue this great work, here in the town where I grew up, and across all of western Massachusetts, to achieve a higher state of caring for the people we serve,â€ Keroack added.
Keroackâ€™s father, Dr. Alvin Keroack, served the Sixteen Acres community of Springfield for many years as a general practitioner and occasionally brought his son Mark
to what was then Springfield Hospital
(now Baystate Medical Center) for rounds.
