Donald "Donny" F. Horstmann, formerly of Beaver Dam, passed away unexpectedly on Friday, February 8, 2019 at his home in Fitchburg.

A man who lived life guided by his heart, he gave every piece of himself if you gave him the opportunity. A graduate of Beaver Dam Senior High in 1989, Donny found his passion as a Military Intelligence Officer in the Army following high school. At the end of his military service he accepted a position with The Analytical Sciences Corp. (TASC) where he continued to flourish and prove to the world he was more than a rocker with a mullet, he was exceptional. Guided by his love for family and Wisconsin, he moved back home in 1998 where he worked a short time as a Correctional Officer. Donny found his own personal bliss in music, the Green Bay Packers and family. He grew to find happiness from the simplest of things, a lesson all who knew him benefited from.

He will be missed by his mother, Karen (Ascherien) Horstmann; his sister, Heather (Joseph) Jarden; half-sister, Danyel (Clyde) Geimer; several nieces, nephews and many who called him "friend". He was preceded in death by his father Donald H. Horstmann.

A gathering to celebrate Donny's life will be held on Friday, February 15, 2019 at Cornerstone Funeral & Cremation Services, 135 Keller Blvd., Beaver Dam from 5:00 - 6:30 p.m. A Time of Remembrance will be held at 6:30 p.m.

Cornerstone Funeral & Cremation Services in Beaver Dam is honored to be serving the family.
