About Us

Independent. Efficient. Client-First.

 

Our Story: A Legacy of Serving Individuals throughout Wisconsin and the U.S.A.

The Power of Shared Experience
We often joke about being "set in our ways." For Mark, his affinity for hand-written note taking during client meetings has remained consistent through his decades of specialized focus on Medicare and insurance solutions. For Kelly, it’s embracing new technologies to drive efficiency—a skill continuously evolved throughout her 20 years leading strategy and client partnerships in the broader healthcare industry.

Together, we cover every angle of your care, ensuring you receive transparent guidance, recommendations rooted in your best interest, and responsive, organized service that respects your time.
