About Mark J. Wuellner

Mark J. Wuellner

Chief of Staff

As the Chief of Staff for Brown Glier Law, Mark is charged with providing executive leadership to the firm.  His portfolio includes team development, operational excellence and client & community engagement.  As a lawyer and seasoned executive, Mark brings unique perspective and experience to the Chief of Staff role.

Prior to joining BGL, Mark capped a 12-year tenure in the public sector by serving as the Executive Director of the Indiana Bond Bank (IBB) a public sector organization charged with financing critical projects for schools, communities, libraries and other units of government.  Under his strategic vision, the IBB team invested over $200 million to address aging critical infrastructure statewide.  Mark’s belief that innovation comes from all places resulted in “The Flipping Finance Challenge”, a 1st-in-the-U.S. design sprint focused on delivering crowdsourced solutions to real Indiana public finance challenges.

Mark joined the IBB having served as the Deputy Chief of Staff for the Indiana Office of the Lieutenant Governor, where he served 3 Lt. Governors, oversaw the performance of 5 state agencies and served as general counsel.  Mark began his tenure in public sector service at the Indiana Housing and Community Development Authority (IHCDA), where he started as in-house General Counsel, and left as Deputy Executive Director & Chief of Staff.  During his tenure, IHCDA implemented an award-winning continuous improvement process and improved staff satisfaction and retention metrics.

Prior to joining the public sector, Mark practiced law at a mid-sized Indianapolis-based law firm, where his practice included assisting businesses of all types and sizes with corporate governance, business transactions, mergers and acquisitions, private equity and securities offerings.

Mark earned his Juris doctorate with a concentration in Public Law from Cornell Law School, where he participated in the International Law Institute at the Université of Paris I, in Paris, France. He earned his cum laude Bachelor’s degree from Butler University, where he was a student-athlete on Butler’s first Men’s Cross-Country team to reach the Division I Championships. (As the cross-country equivalent of a benchwarmer, he did not run in the championships, but cheered loudly on the sidelines.)

Mark serves on the Boards of Directors for the Immigrant Welcome Center and the Brownsburg Lacrosse Club. While not at work or volunteering, Mark spends time with his wife, son and daughter, usually playing one of any variety of sports outside or getting challenged to a board game inside.
