Don proudly served in the United States Marine Corps from 1951-1953. He joined Wauwatosa Realty Company (now Shorewest Realtors) in 1954 and retired in 2016 after 62 years of dedicated service. Don was promoted to Manager of the Closing Department in 1957, was elected to the Board of Directors and as Corporate Secretary in 1961, became Executive Vice President in 1976, President in 1999 and Chairman of the Board in 2003.

Don enjoyed spending time with his children and grandchildren.  He and Katy were loyal Marquette University basketball season ticketholders for over 50 years.  Don was an avid gardener and spent many weekends working in his yard.   He touched many lives by writing thousands of personal notes over the years recognizing the accomplishments of his colleagues, children and grandchildren.  

The family wishes to express their gratitude to Don’s caregivers at Touching Hearts and Seasons Hospice.
