As his clients' lives evolved, so did his practice. He now helps Physicians begin to address Estate Planning and Distribution Planning as they get closer to the “Retirement Red Zone." Once he has made sure his client's Retirement Plan is addressed, he shifts the discussion toward wealth transfer, Estate Planning, and philanthropic aspirations.

Shaun is a published co-author of The Physician’s Guide to Financial Independence and The Dentist’s Guide to Financial Independence, as well as a co-author to numerous revisions to these titles. He is additionally a published co-author of Promises Kept (2017). 

Shaun is a 1990 graduate of the University of Wisconsin-Madison. He has been awarded the designation of Accredited Estate Planner (AEP) from the National Association of Estate Planning Counselors. He has been awarded the designation of Certified Exit Planning Advisor (CEPA) from the Exit Planning Institute of Chicago. Shaun also has been awarded the Chartered Financial Consultant (ChFC), and Chartered Life Underwriter (CLU) from the American College.

Additionally, he founded Stop Alzheimer's Now (SAN) in 2013 with the goal of raising awareness and funding for Alzheimer's Research. Of note, SAN has been able to endow a research chair at Temple University’s Alzheimer Center as well as fund research projects at the University of Kansas and the University of Florida to further Alzheimer’s research towards a cure.
