Mark Alan Keller

Mark Alan Keller, aged 60, a resident of Indianapolis, Indiana (formerly of West Terre Haute, Indiana), passed away peacefully on December 23, 2025, after an almost ten-year battle with multiple myeloma. Mark is survived by his wife Susan (Stow) Keller, daughter Kate, son Sam, brother Jay Keller (Cindy), sister-in-law Julie Bailey, brother-in-law David Stow, sister-in-law Becky Frank (Matt), several aunts, uncles, cousins, nieces and nephews, and his dog Penny. He was preceded in death by his parents Jerry and Mary Keller, his in-laws Richard and Amy Stow, and his beloved dog Chloe.

Mark was well loved by all, including his family, neighbors, high school friends, college friends, and former coworkers. Mark never met a stranger. He was kindhearted and would help anyone in need.

He enjoyed working on his classic 1966 Plymouth Satellite and driving it to area classic car shows. He and Susan also enjoyed walking at Fort Harrison State Park and various other walking trails throughout the city.

Mark loved to travel and was always in his ‘happy place’ when visiting Fort DeSoto State Park, where he listened to his classic rock music while relaxing under an umbrella and shelling on the beach. He and Susan also enjoyed their yearly trips to Brown County State Park.

We want to thank all the doctors, nurses, and staff at Simon Cancer Center and everyone from Brighton Hospice Indiana for their compassionate care and treatment of Mark.

A celebration of life luncheon will be held at a future date.
