Cohen & Co to acquire Tassi and Company

Cohen & Co, a Cleveland-headquartered accounting and consulting firm, has agreed to acquire Tassi and Company, a Chicago-area accounting and consulting firm.

Founded in 1990, Tassi and Company is based in Deer Park, IL and has approximately 35 employees. The firm serves the real estate industry – including owners, developers, managers, and investors – with offerings in outsourced fund and partnership accounting, property management and development accounting, construction draw accounting, and tax services.

The acquisition, which is expected to finalize at the end of the month, will expand Cohen & Co’s real estate sector and its Chicago presence, where it has a downtown location. The Tassi and Company team will remain at their current office in Deer Park.

"The real estate and construction industry is an important growth area and one that we've made a priority for investment. This transaction will provide additional expertise and scale for the benefit of our clients, as well as new career path opportunities for employees of both firms,” said Chris Bellamy, CEO of Cohen & Co.

Cohen & Co received a strategic investment from private equity firm Lovell Minnick Partners in December 2024. As part of the transaction, Cohen & Co adopted an alternative practice structure and split its attest and non-attest services into separate entities.

Cohen & Co subsequently acquired Cleveland-based Tax and Wealth Management Inc. in January 2025.

"This is the natural next step for our firm as we plan for our future,” said Joe Tassi, founder and principal of Tassi and Company. “We are impressed with Cohen & Co and are confident our clients and teammates will benefit from their leadership and strategic vision."

Cohen & Co is the 47th-largest accounting and consulting firm in the US, according to IPA, with $153.9 million in annual revenue. The firm has more than 800 professionals across 13 offices in the US.
