William Martin "Marty" Haak

William Martin Haak (Marty), 80, of Lake Villa, Illinois, passed away on March 5, 2025. He was born on February 18, 1945, in York, Pennsylvania, to William and Katherine (Martin) Haak. He was the third of five children, preceded in death by his siblings Bonnie Lohman Haglund and Lloyd Haak. He is survived by his sister Patricia Haak and brother Gerry Haak. Marty was preceded in death by his long-time partner, Thomas (TJ) Ferro, in 2009. Marty grew up in Baltimore, Maryland, and graduated from Towson Catholic High School. He later earned his degree from St. Francis College in 1966. After college, he proudly served in the United States Air Force from 1967 to 1969 before being honorably discharged to return home and care for his family following the death of his father. A dedicated professional, Marty spent his entire career in sales, specializing in machinery for heavy and light construction, rough terrain materials handling, and industrial applications. His work ethic and commitment to excellence earned him the respect of his colleagues and clients. Marty was a devout member of the Catholic Church, actively serving as an altar assistant, Eucharistic minister, CCD teacher, Sacristan, and leading the Compassionate Care Ministry. His deep faith and dedication to his church extended beyond service, as he was also a devoted member of the Knights of Columbus since 1972. Throughout his years with the Knights, Marty served in many capacities, including Grand Knight of his council and Faithful Navigator of his 4th degree assembly. He also led numerous community-focused events, including the rummage sale, Christmas tree sales, and Tootsie Roll sale, while volunteering for many other charitable causes. After retiring, he took great joy in spending time with his grandchildren. Marty cherished the role of "Papa Marty" and was often found walking two of his grandchildren, Will and Ellie, to and from school, providing snacks, and refereeing neighborhood games. He found deep happiness in the love and laughter of his family. He is survived by his six children, 11 grandchildren and 2 great-grandchildren: Julie Kocur (husband Dave Kocur, grandchildren Meghan and Kristin), Dave Haak (wife Sue Ellen Haak, grandchildren Ellie and Will), Bob Haak (grandchildren Zoey, Bristol, and Tennyson (TJ)), Karen Schatzer (grandchildren Delaney and Cecily), Sarah Haak (grandchild Emma), and Pam Olympio (husband Joe, grandchild Lexi, and great-grandchildren Mikey and Daniel). William will be remembered for his unwavering faith, his unrelenting work ethic and his tireless service to his community.
