Thompson Flaherty is expanding north. As of May 2026, we are officially serving small businesses, professionals, and families across the Chicago metro area, including Lincoln Park, Near North, the West Loop, Streeterville, Lake View, and the surrounding suburbs from Evanston to Naperville.
We started in the Metro East. We grew into the St. Louis region. The Chicago expansion is the natural next step. Our team is Illinois and Missouri-licensed, and our year-round CPA approach (the one where you actually hear from us between filings) translates the same way across the river.
If you are a Chicago business owner who has been looking for a CPA firm that does tax, bookkeeping, and strategy work as a single relationship instead of three separate transactions, we’d love to talk. Visit our new Chicago CPA page for details on what we do and how the engagement works, or get in touch to start a conversation.
