US-based tax and accounting firm Cohen & Co has acquired Tassi and Company, a boutique accounting and consulting firm based in Chicago.
Financial details of the deal have not been disclosed.
The transaction, expected to close at the end of March 2025, marks a step in Cohen & Co’s growth strategy.
It is expected to enhance the firm’s national real estate service offering and expand its presence in the Chicago market.
Founded by Joe Tassi in 1990, Tassi and Company employs approximately 35 people. The firm focuses on providing tailored services to real estate owners, developers, managers, and investors.
It also offers outsourced fund and partnership accounting, property management and development accounting, construction draw accounting, and tax services.
Following the closure of the deal, all professionals from Tassi and Company will join Cohen & Co, including Joe Tassi, Terri Nietzel, and Gretchen Sampson, who will join as partners.
The team will continue operating from its current office in Deer Park, Illinois.
Tassi and Company founder and principal Joe Tassi said: “Cohen & Co shares our core cultural and entrepreneurial philosophies rooted in client service and taking care of our people.
“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.”
Calfee, Halter & Griswold served as legal counsel to Cohen & Co, while Creative Planning provided legal counsel to Tassi and Company during the transaction.
Cohen & Co CEO Chris Bellamy said: “We are excited to welcome Tassi and Company to our firm.
“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’s growth plans are further supported by its recent investment from Lovell Minnick Partners in late 2024.
This investment is designed to meet the increasing needs of the firm’s clients across various industries and markets.
Earlier in 2025, Cohen & Co also completed its acquisition of Tax and Wealth Management, based in Cleveland, Ohio, marking another milestone in its expansion efforts.
