Gregory H C Stephan

Gregory H C Stephan ( grew up in Valley City )
His family mourns the loss of beloved Husband, Father, Brother, Uncle, and Grandfather, Gregory H C Stephan. Gregg passed away March 5, 2025, the third son and fifth of six children, born to LAW Stephan and Kolleen "Pat" (Triebold) Stephan of Valley City ND. He was preceded in death by his brother William, and his sister Elizabeth and survived by three siblings; Richard, Daniel, and Kathleen. He is also survived by his wife, Karen (Nelsen) Stephan; three daughters, Patricia, Michelle, and Katherine, and six grandchildren: August, Aeryn, Elizabeth, James, Maxton, and Morgan.
After graduating from Valley City High School, Gregg went to the University of North Dakota, Grand Forks. He earned a B.S. in Chemical Engineering, graduating Magna Cum Laude and was inducted into Tau Beta PI ( a society recognizing academic achievement and exemplary character in engineering students). Gregg spent the majority of his professional years as a Manufacturing Leader at 3M in positions across the Midwest, the majority of time focused on the development and manufacturing of filtration products. He took pride in his team and 3M's continued position as an innovation leader in filtration, including the development of N95 masks, Filtrete (TM) electrostatic filters, and Thinsulate(TM) products.
After Gregg retired from 3M, he spent his remaining years with Karen in their home in Inver Grove Heights MN. Never one to be idle, he spent his remaining years devoted to archiving family films and pictures, the creation of which occupied many of his early years. He possessed a great interest in genealogy which he pursued with his brother, Richard. One of Gregg's passions was repairing electronics, especially pinballs and jukeboxes. He had a well deserved reputation for being able to repair absolutely anything.
A Celebration in Honor of Gregg's Life and our Love of him will be at our home May 18th from 1 PM to 4 PM. All who would like to join us are welcome. The family requests, in lieu of flowers, that donations may be made to Lewy Body Dementia Association (LBDA) or Beyond Hospice, 6025 Upper 35th Street N Oakdale MN 55128.
