Helen Louise McMahon

Helen Louise McMahon, 65, of Westmont, passed away in the care of hospice in her sister’s home on February 4, 2026, after a courageous battle with an extended illness. Born February 19, 1960, in Waynesburg, to Rev. Donald and Leona Chamberlain, Helen entered the world with a song in her heart and a story to tell. Helen was preceded in death by her father, Rev. Donald Chamberlain; her former husband Michael McMahon, her brother-in-law, Bill McMahon; and her infant nephew, Brandon Miller. Helen is survived by her mother, Leona Chamberlain (Ritchey); her sister, Donna (James) Zimmerman; sister-in-law, Kate Vaccaro-McMahon; her sons, DJ (Summer) McMahon and John McMahon; and her beloved grandson, Xae Michael McMahon. She proudly held the title of “Aunt Helen” to Brittany Miller, Cameron (Rachel) Miller, Lauren Zimmerman, Allison (Chas) Huckestein, Nathan (Kayla) Zimmerman, and Tyson (Abby) McMahon, along with many great-nieces and nephews and a wide circle of family and friends who will miss her dearly. A 1978 graduate of North Star High School, Helen was active in chorus and earned the opportunity to sing at county, district, and state levels. She later earned an Associate Degree in Business from Eastern Nazarene College in Quincy, Massachusetts. Helen met her late husband, Michael McMahon, and they answered the call to travel Evangelism in the Church of the Nazarene for several years allowing Helen to use her musical talents in ministry. They transitioned to church ministry in California where they raised their two sons. Returning to Pennsylvania with her boys, Helen was employed for many years at the Hiram G. Andrew’s Center in various positions, most recently as a Financial Assistant.  Helen loved her job and her coworkers which was reflected in her commitment to work despite her health challenges. In her free time, Helen could often be found crocheting or quilting, creating cherished handmade gifts. She had a special talent for spying valuable items in thrift stores and yard sales, always ready with a rescued gem for “show and tell.” She attended West Hills Community Church in Westmont, where she enjoyed small groups, and also worshiped at The Emmanuel Church in Johnstown. Even in the midst of her illness, Helen continued to encourage others and boldly share her faith. She will be remembered for her strength and devotion to the Lord. The family extends heartfelt thanks to Helen’s coworkers at the Hiram G. Andrew’s Center for their kindness and incredible accommodations that allowed her to continue doing the work she loved. Heartfelt love and appreciation are extended to UPMC Family Hospice for their compassionate care, and to the many friends and family who surrounded Helen with love.
