Mark is a Kansas City native, graduate of Rockhurst High School, and Marine Corps Veteran who served on active duty as an infantry officer for 8 years following graduation from the University of Kansas. He joined the Federal Reserve Bank of Kansas City in 1986 and went on to hold senior executive posts at Federal Reserve Banks in Oklahoma City, Los Angeles, and San Francisco before retiring from the Richmond, Virginia Reserve Bank as its interim CEO and president in 2018.

Mark first met Benilde Hall founder Godfrey Kobets in 1992 as a volunteer at the DeLaSalle Education Center. Since then, Mark has served on numerous community not-for-profit and academic boards as an adviser, board member, or trustee. His post-Federal Reserve work has included service as an independent director on a NASDAQ-listed company board, advising banks and financial services firms, and, upon returning to his hometown of Kansas City, serving Benilde Hall as a board member. Mark has said, “The important work of the Benilde Hall team is a key asset in serving our clients and contributes to the health of the Kansas City community more broadly.”

In addition to his studies at Rockhurst and KU, Mark earned a master's degree in international relations from the Fletcher School of Law and Diplomacy, Tufts University. He is married to another Kansas City native, Julie Riggs Mullinix.
