Michael Frohna

Michael Frohna – PresidentLeadership

When Michael first started his professional career, his passion for education had him interested in becoming a high school teacher. While he changed directions professionally, education remained a high priority and he became actively involved in education initiatives including Partners in Education (Green Bay), Business Education Alliance (Fox Cities) and several other education-focused organizations.

In 2017, after nearly 30 years of fundraising leadership experience within healthcare, higher education and health-related organizations, Michael became President at JA, where the mission was a perfect combination of his professional interests and personal passions. As President, Michael engages with every aspect of the organization, including working alongside a dedicated board of directors, volunteers, and team members. His greatest responsibility is to enable the forward momentum of JA’s mission while preparing the organization and team for the future.

Outside of JA, Michael is drawn to the outdoors. He enjoys reading in a hammock, golfing and has a love-hate relationship with photography. In another life, he might have become an electrician or a plumber.


Mari Stein

Mari Stein – Sr. Regional Director (NWC & SC)Leadership

After receiving her Business Management degree from the University of Wisconsin-Madison, Mari’s professional career was largely spent in retail management and purchasing, followed by 12 years as a stay-at-home mother. In 2007, she decided it was time to join JA as an Elementary Program Manager, not only so she would be back in the workforce, but so she could also continue to be involved with her kids at their schools while helping other students in the area.

Over the last 14 years, Mari’s role with JA has evolved from Program Manager to Marketing & Development Manager and then Regional Director to Senior Regional Director where she now oversees 2 of the 4 JA regions across the state of Wisconsin.

As Senior Regional Director for both the North & West Central Region and the Southcentral Region, she works with staff across six area offices to oversee their operations, working closely with them to develop fundraising strategies, program strategies and regional events.

Mari is a long-time resident of the Wausau area where she resides with her husband. They have two sons, one who just graduated from college and another in his third year of medical school. In her free time, Mari likes to enjoy the great outdoors while spending time at the family cottage up north. Each year she travels to Anna Maria Island in Florida to “escape” the Wisconsin winters.
