Steven Wayne Coulman

Steven Wayne Coulman, of Hebron, Illinois, passed away on November 7, 2026, in Hebron. He was born on October 11, 1952, in Harvard, Illinois.

Steve graduated from Alden-Hebron High School in 1970 and spent his entire career as a sheet metal mechanic for HVAC companies, including Ellison Plumbing and Heating, Althoff Industries, and Jensen Plumbing and Heating. He believed in doing things the right way, and that care showed in every job he took on. A perfectionist in everything he did, Steve was truly a jack of all trades. In his spare time, he helped build houses for family and friends, always lending a hand and never turning anyone away.

Beyond his work, Steve found joy in the activities he enjoyed most. He loved to golf and had a deep passion for model trains. Winter brought another favorite pastime, snowmobiling with his wife and friends in Lakewood, Wisconsin. One memory he held especially close was a day golfing with Judy at Nicolet Country Club, when she made a hole-in-one.

Above all, Steve’s life was rooted in devotion to his family. He is survived by his beloved wife, Judy Coulman, his partner of 55 years; his daughters, Susan Kastning, Beth Coulman, and Lisa (Thomas) Lynch; his five grandchildren, Nicholas, Joshua, Olivia, Austin, and Madison; his brother and sister, Gary (Shirley) Coulman and Laurie (Garrette) Long; and many nieces, nephews and cousins, who will carry forward cherished memories of his steady presence, generous spirit, and the example he set through hard work and kindness.

He was preceded in death by his parents, Ralph (Buster) Coulman and June Whaples.

Family and friends are invited to gather for visitation on Thursday, November 12, 2026, from 3:00 p.m. to 5:00 p.m. at Derrick Funeral Home & Cremation Services, 800 Park Dr., Lake Geneva, Wisconsin 53147. A funeral service will follow at 5:00 p.m.
