Honest to a fault, he’s a firm believer that transparency, accountability and mutual benefit are the foundation of any lasting relationship.

He lives in Pittsburgh with his wife, his dog, and two unusually large cats. Every few weekends Mike runs a Dungeons and Dragons game for his friends, it’s a bit like a poker night but with more math and silly voices.
