John O'Connor

I’m an assurance partner with 30 years of experience at both Big Four and middle-market accounting firms. I am also on the leadership team of Plante Moran’s private equity practice. Working as an M&A advisor, I help my clients maximize value on the sell side, minimize tax exposure, and accelerate post-acquisition integration. I specialize in audit, tax sales readiness planning, buy-side due diligence, post-acquisition tax, and financial reporting. All of my clients are private equity-owned businesses in the manufacturing, aerospace, technology, transportation, and service sectors.

I frequently present to boards on a variety of accounting, business, and tax issues. I currently serve on the following boards of directors: ACG Chicago, Catholic Charities of the Archdiocese of Chicago advisory board, AgeOptions, and DePaul University Ledger and Quill. I have a B.A. in accounting from DePaul University and an M.B.A. from the Kellogg School of Management at Northwestern University.
