Grand Rapids-based Spectrum Health, one of Michigan's largest not-for-profit health systems, and Lakeland Health, a three-hospital system based in St. Joseph, signed final merger agreement papers Monday.
Spectrum Health Lakeland is now a division of Spectrum Health, a 12-hospital nonprofit integrated health system with an employed medical group and health insurance company.
Lakeland Health will continue to be governed by a local board of directors that will oversee operations and ensure capital investment and philanthropic efforts on a local level, officials said.
"Lakeland Health is an exceptional organization and we are thrilled they are part of Spectrum Health," Tina Freese Decker, Spectrum Health's president and CEO, said in a statement.
"Lakeland's focus on serving the community, embedding high quality care practices and emphasizing the importance of including and engaging patients in their care aligns well with Spectrum Health's culture. I am inspired by the enormous possibilities that lie ahead for the team members and physicians at Lakeland as well as throughout our entire health system."
Loren Hamel, M.D., Lakeland's president and CEO, said being a part of Spectrum will help the nonprofit system build its pediatric and specialty care services and access Spectrum's state health network. No information was available on promises by Spectrum to invest in capital or clinical services projects.
"Health care is constantly changing, and even as we embrace those changes, what hasn't changed is our commitment to take great care of our friends and neighbors," Hamel, who will become chief clinical transformation officer, said in a statement.
Lakeland operates three hospitals and outpatient facilities with more than 4,000 workers and 450 doctors, nurses and other providers.
