Brinker Simpson & Company provides accounting, tax, audit and advisory services across Greater Philadelphia, South Jersey, Delaware and nationwide.
Bob Simpson, CPA, MST and Tom Brinker, CPA, founded the firm in 1989 on a simple idea: know your clients well enough to give advice that matters. Tom went on to lead Arcadia University's accounting department, while Bob grew the firm on long-term relationships, direct access to senior professionals and hands-on involvement that larger firms can't always deliver.
Michael Simpson, CPA, CVA, joined in 1993 and became Managing Partner in 2022 after nearly three decades alongside Bob, shaping the firm's valuation, tax and consulting services. He's building on that foundation with a sharper focus on advisory, strategic growth and the next generation of talent.
