Cohen & Co Announces Strategic Acquisition of Tassi and Company

by Chris Bellamy

March 06, 2025

Cohen & Co, one of the top tax and accounting firms in the U.S., is pleased to announce the acquisition of Tassi and Company. Based in the northwest suburbs of Chicago, Tassi and Company is a boutique accounting and consulting firm providing services tailored to the real estate industry. The transaction, expected to close at the end of March 2025, is a meaningful milestone in Cohen & Co’s growth strategy, enhancing its national real estate service offering and expanding the firm’s presence in the Chicago market.

Founded by Joe Tassi in 1990, Tassi and Company has approximately 35 employees and serves real estate owners, developers, managers and investors. Specifically, the firm provides outsourced fund and partnership accounting, property management and development accounting, construction draw accounting and tax services.

“We are excited to welcome Tassi and Company to our firm,” says Chris Bellamy, Cohen & Co CEO. “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.”

“Cohen & Co shares our core cultural and entrepreneurial philosophies rooted in client service and taking care of our people,” says Tassi and Company Founder and Principal Joe Tassi. “This is the natural next step for our firm as we plan for our future. We are impressed with Cohen & Co and are confident our clients and teammates will benefit from their leadership and strategic vision.”

Part of a longer succession plan for Tassi and Company, all the firm’s professionals are expected to join Cohen & Co when the transaction closes. This includes Joe Tassi, Terri Nietzel and Gretchen Sampson, who will be joining the firm as partners. The team will remain in its current Deer Park, Illinois, office space. Combined with Cohen & Co’s existing downtown Loop location, Chicago becomes one of Cohen & Co’s largest geographic markets.

Calfee, Halter & Griswold LLP served as legal counsel to Cohen & Co. Creative Planning, LLC served as legal counsel to Tassi and Company.

Cohen & Co announced a strategic growth investment by Lovell Minnick Partners in late 2024 to help meet the growing needs of its clients across various industries and markets. The firm’s most recent acquisition was Cleveland, Ohio, based Tax and Wealth Management, Inc., which closed in January of this year.
