Todd Kolosso


Todd Kolosso has had a long and varied career path, which has most recently brought him to baseball. Todd got his start in owning and managing a commercial real estate portfolio, but has since added retail apparel and in-store radio marketing to his list of endeavors. In 2019, he partnered with David Casey to bring Milwaukee Baseball Academy II to one of his buildings, and has not looked back in the baseball world. Now, with David Casey, part owner of MBA II, and the Northwoods League team Lakeshore Chinooks, Todd takes particular pride and enjoyment from the Rivets. He spent all of last season as a fan, cheering right along with the Rivets’ sponsors, season tickets holders and highly-enthusiastic staff! He looks forward to our next Championship season, both on and off the field.

Todd is a current owner at Milwaukee Baseball Academy, Lakeshore Chinooks, and Rockford Rivets along with David Casey.
