IHA acquires Ann Arbor Hematology Oncology Associates, plans expansion

By Nathan Bomey

Ann Arbor-based physician network Integrated Healthcare Associates said this afternoon that it has reached a deal to acquire Ann Arbor Hematology Oncology Associates PC, which serves some 7,000 patients.

The deal comes about seven months after Novi-based Catholic health care group Trinity Health's St. Joseph Mercy Health System acquired IHA, which has nearly 1,000 doctors, nurses and other staff members.

One of AAHOA's three offices is located next to St. Joseph Mercy Hospital in Superior Township.

AAHOA, formed in 1978 by Charles Gehrke, has 24 employees, including seven doctors, and offices in Ann Arbor, Brighton and Chelsea.

An IHA spokeswoman told that the network plans to maintain AAHOA's staff and offices and plans to seek opportunities to expand the practice. IHA serves about 255,000 patients a year.

“IHA’s service and performance based operating systems will complement AAHOA’s clinical capabilities and patient-focused approaches to deliver added value to patients," IHA CEO Bill Fileti said in a statement. “By combining strengths, IHA and AAHOA will be more responsive to the needs of patients across the region. This integration moves IHA another step closer to its vision of a truly integrated, multi-specialty health delivery network."

The deal is expected to be completed by July 18. IHA declined to release financial details.

"Our integration with IHA will further our ability to provide patient-centered care and enable us to expand the programs we offer to other sites to better support the community” said Jay Winegarden III, president of Ann Arbor Hematology Oncology Associates, in a statement. “With an aging population of baby boomers around the corner, the timing of this integration couldn’t be better as we prepare to meet that challenge.”

I sure hope they do not lay off the senior/dedicated employees, just to save a buck.
