United Methodist Communities and Porter Hills have announced plans to consider joint governance and leadership, which could lead to a $150 million company serving seniors in 22 Michigan counties.

The combined venture would put it among the top 75 largest nonprofit senior living providers nationally, based on 2017 LeadingAge Ziegler 150 listings, officials said. UMRC, Porter Hills and their affiliates employ 1,300 staff, who tend to more than 4,600 older adults via 24 service lines and locations.

“Both our organizations have agreed to move forward with this process as a means of sharing our knowledge, skills and resources for the betterment of senior services across Michigan,” said Mary Wagner, chairwoman of Porter Hills’s governing board, in announcing plans last week. “We think we can deliver better results through mutual collaboration.”

The due diligence process is expected to last at least through December, the companies said in a joint release. Services offered range from affordable housing to assisted living, memory care, rehabilitation, skilled nursing, hospice and Programs of All-Inclusive Care for the Elderly.

“While these numbers are impressive — and potentially transformative to Michigan’s landscape of senior living services — size is not the goal for either UMRC or PH,” said Kim Hoppe, Porter Hills’ senior vice president of financial and corporate services. “It has to be the right fit not just for us, not just for UMRC, but for the individuals and families we serve.”
