Michael "Mac" McMahon

In Loving Memory of Michael “Mac” McMahon

April 18, 1956 – April 13, 2026

It is with deep sorrow that we announce the passing of Michael “Mac” McMahon, a calm and caring man defined by his integrity and unwavering love for his family. Mike was born on April 18, 1956, and peacefully transitioned from this life on April 13, 2026. He will be greatly missed and forever remembered by all who knew him.

Mike is survived by his beloved wife, Ann—his best friend, the love of his life, and his partner-in-crime for over 50 years. He was the devoted father of Jennifer (Dan) Rossler and Michael McMahon, who were truly the lights of his life. He was the adored grandfather of Joshua, Kailey, Mikey, and Isla, and a dear father-in-law to Dan Rossler, whom he loved as his own.

Mike is also survived by his brother, Tom; his sisters, Pat and Doreen; and many nieces and nephews who loved him immensely. He will be deeply missed by his best friends of over five decades, John and Kate.
