MaineHealth, the state’s largest health care provider, and parent of both Pen Bay Medical Center and Waldo County Hospital, has tapped a New Jersey physician with extensive experience as a medical leader to be its next chief medical officer.

Dr. Joan D. Boomsma, currently the chief medical officer with Atlantic Medical Group of Morristown, N.J., will join MaineHealth in September. She replaces Dr. Robert McArtor, who had come out of retirement to step into the chief medical officer role on an interim basis.

In her new role, Boomsma will work across MaineHealth’s system of hospitals and health care practices in southern, western and central Maine, as well as Carroll County, N.H., to help the organization’s physicians fully leverage the resources of the system.

“Our goal is always to provide the best possible care to patients, as close to home as possible,” said Bill Caron, president of MaineHealth. Dr. Boomsma will work with our physicians to see to it that our patients receive first-rate, comprehensive primary care as well as access to our world-class specialists.”

Caron said Boomsma’s responsibilities will extend to many other facets of the organization in areas such as population health, safety and quality, payment reform and price transparency as well as employee engagement, especially among MaineHealth’s physicians.

“Dr. Boomsma will be a key member of our team, helping us to achieve our vision of working together so our communities are the healthiest in America. And I have to say we were all impressed with her credentials and keen instincts,” Caron said.

Boomsma has extensive experience as a physician leader. After receiving her undergraduate degree from Calvin College in Michigan and attending the University of Michigan Medical School, she completed an internal medicine residency at Northwestern University. She went on to complete a fellowship in pulmonary and critical care at the University of Illinois College of Medicine, followed by a distinguished clinical career practicing at Northwestern Memorial Hospital in Chicago. She subsequently earned an MBA from the Kellogg Graduate School of Management at Northwestern University.
