Our Lord Has Called Ken Mumy to Ride with the Angels
Ken Mumy, 78, of Ocala, FL, and Metamora, MI, passed into His loving arms on February 11, 2026. Beloved husband, father, grandfather, brother and friend.
Mumy was known for his kind and compassionate nature and his love of The American Quarter Horse. He served five years on the American Quarter Horse Association’s Executive Committee, becoming president in 2008. Ken was humbled and deeply honored to be inducted into the AQHA Hall of Fame in 2014.
Reflecting on his time with AQHA, Ken often referred to his dream to reinvigorate the AQHA Championship as one of his stated goals during his service. Performance Halter was “born” as a result of these efforts. Others commended him on his abilities to draw people together, citing his highly successful efforts to increase engagement among hundreds of national and international affiliate organizations.
Mumy graduated from Michigan State University’s Construction Management program in 1969. His career was spent deeply involved in management and compliance consulting, guiding environmental systems for major mining and manufacturing. During his career, he owned two different environmental service companies which focused on remediation of contaminated properties and groundwater preservation in the state of Michigan. He ended his career as a manager in the Environmental Health and Safety Division of BSI Americas (British Standards Institute of The UK).
Ken was a proud director of both the American and Michigan Horse Councils, receiving Michigan’s prestigious Catalyst Award in 2011. The award is inscribed “your efforts and communication skills have made a significant contribution to the renaissance of the Michigan Horse Industry.”
He was also a 40-year member of the Michigan Quarter Horse Association proudly serving on its Board of Directors and as President. He was inducted into the MQHA Hall of Fame in 2011.
Ken leaves behind a family who adored him and looked up to his constant example of loving kindness. He is survived by his wife of 57 years, Maryellen; children Lisa (Todd) Smith; Michelle (Tom) Sierakowski; K.C. (Kenneth Cameron)Mumy; grandchildren Kaitlyn (Reece) Fisher; Matthew Sierakowski; Bella Kate Smith. Brother Craig (Deb) Mumy; sister Pamela (Guy) Martin and all his beloved “framily” of lifelong friends who prayed and held the family in their hearts throughout his illness. He was preceded in death by his parents, Roscoe and Patricia Mumy and brother, Scott Mumy.
