Mike has over thirty-five years of public accounting experience servicing businesses in the not-for-profit, manufacturing, and service sectors. He is a founding partner of Grandmaison and Tripoli,LLP and has proudly serviced its clients for over thirty years. He has been a guest speaker at many seminars focusing on financing for businesses, personal, business and education tax planning.

Mike has been lucky enough to have family support from his lovely wife Ann Marie and his three children Kathryn, Eric and Dan.

As a lifelong Boston Red Sox fan, he is thrilled that the Red Sox won the World Series in 2004, 2007, 2013 and 2018. In fact, he was able to attend all four games of the World Series in 2007 and he attended game 6 of the World Series in 2013 when the Red Sox won the championship at Fenway Park - "What a thrill!!"

His goal is to attend every major league baseball park. At this time, he has attended 28 different ballparks. Since new ballparks keep getting built, he still have eight parks to go including St. Louis, San Francisco, Minnesota, Kansas City, Cincinnati, Detroit and New York Mets.
