He began his career at the Aid Association for Lutherans (now known as Thrivent) in Appleton, Wisconsin, where he focused on real estate and insurance.

​Mark's dedication to environmental and community causes is evident in his various affiliations and roles. He is a life member of the Nature Conservancy and holds memberships in several national conservation organizations. His commitment to community service is further reflected through his position as a Board Member of the Landmark Square Condominium Association and his role as Secretary to various corporate boards of directors.

Mark's passion for environmental preservation was ignited during a pivotal moment in his childhood. At the age of ten, while visiting his grandmother's home, he listened intently as his father and uncles reminisced about the Illinois River. They painted vivid pictures of a time when the river was abundant with shellfish and teeming with aquatic life. Curious and concerned, young Mark asked what had happened to the river. His relatives explained that in an effort to protect Lake Michigan from the city's mounting pollution, the course of the Chicago River was reversed, diverting the contaminated waters into the Illinois River. This decision had devastating consequences for the river's ecosystem, leaving Mark with a profound sense of sadness and disappointment. This formative experience instilled in him a lifelong commitment to restoring and preserving the natural world.
