League Leadership

Sheridan McGuane Baseball is an all-volunteer run organization. We are a community baseball organization that seeks to build the future generation of our nation’s leaders. Our Board of Directors seeks to lead from the same principles that we build in our players: servant leadership, community and citizenship.

When Joe’s not coaching baseball, he’s working as the CFO at Sprout Social, a Chicago-based software company, or spending time with my family. Joe has three kids, two boys (13 and 15) and one daughter (9), and an amazing wife.

“I have been coaching little league baseball for over 10 years. Sheridan McGuane Baseball has brought a lot of joy to me and the community.
