Ben McMahon

Treasurer, National Stearman Fly-In

I was a tax partner in RSM, LLP (a CPA firm) in the  GalesburgOffice retiring in November 2015 after 41 years.  My wife, Mary, and I celebrated our 50th wedding anniversary in  January 2024.  We both love Galesburg and plan to live here  permanently.

While I was at RSM, our office prepared the IRS and  Illinois tax filings for the Stearman Fly-In for many years.  I joined the Board of Directors and was named Treasurer in 2016.
