MaineHealth, parent of Pen Bay Medical Center and Waldo County Hospital, has tapped a veteran chief information officer from a Long Island, N.Y., healthcare system to lead the Maine organization’s systemwide information technology efforts.

Marcy Dunn, currently senior vice president and chief information officer at Catholic Health Services of Long Island in Melville, N.Y., will join MaineHealth this fall as senior vice president and chief information officer. She replaces Andrew Crowder, who left MaineHealth in January to take a role with a healthcare system in California.

In her new role, Dunn will be responsible for IT operations across MaineHealth’s system of nine member hospitals and other healthcare providers serving southern, western and central Maine, as well as Carroll County, N.H.

Dunn began her career on the front lines of the healthcare information world as a billing center manager in Albany, N.Y. Over a career spanning more than 30 years, she has stepped into roles with increasing responsibility. She was director of information services and later chief information officer at Episcopal Health Services in Uniondale, N.Y., throughout much of the 1990s. After working in consulting for a couple of years starting in 1999, she joined Catholic Health Services in 2001, first as director of applications and, starting in 2004, as senior vice president and chief information officer.

During her time as Catholic Health Services’ CIO, Dunn oversaw an extensive upgrade of the organization’s information systems, including implementation of the EPIC electronic medical record platform. MaineHealth is in the process of adopting EPIC across its system.

“The opportunity to lead a team that is transforming healthcare in Maine is very exciting to me,” Dunn said. “MaineHealth is considered a forward-thinking organization, deeply committed to improving the lives of the people and communities it serves. This is a chance to make a difference in a very special place.”
