He met his wife, Alicia (nee Dornacker) in West Bend, WI. They got married on September 5, 1987, and made a life together in West Bend. They had three children, Alyssa, Ryan and Tyler and three grandchildren, Breanna, Gauge, and Brantley.
He is survived by his children, Alyssa (Zach) Stire, Ryan and Tyler Geszvain; grandchildren, Gauge and Brantley Geszvain, Breanna King; parents, David and Jean Geszvain; siblings, Micheal, John, Karen, Patrick, and Matthew Geszvain; Nieces, Katlyn, Ashley, Abbigail, Madison, Gabriela, Allsion Geszvain, Miranda (Bryan) Milligan; Nephews, Dillion (Alisson) Durnford, Andrew, Joseph, Luke Geszvain; Aunts, Grace (Lary "Pokey") Fochs and Phyllis Whelan; cousins, Ian and Corey Fochs, Danny and Lynn Hess, Andrea Roth, and Beckey Christianson.

Best bus driver! He would lay on the horn if cars didn't stop when picking up my kids. To the Family: Sorry for your loss.
