Thomas E. “Tom” Kelleher, a loving and beloved son, brother and uncle, an avid outdoorsman, retired information technology officer, and Acton resident, died of a sudden illness at Beth Israel Hospital Boston on New Year’s Eve 2022.

Tom was born on June 11, 1951 at Fort Leonard Wood, Missouri to Peter T. Kelleher and Marie M. Kelleher.

He graduated from Winchester High School Class of 1969, attended UMass Lowell, and thereafter spent most of his career as an IT specialist for several New England financial institutions, retiring as Senior Security Architect and Assistant Vice President of Citizens Financial Group, Inc. in 2017.

In his very active retirement years, Tom conducted an international internet mapping service for corporations and private nonprofit organizations,

Just as importantly for him, Tom followed up on his years of active service with the Appalachian Mountain Club (Pinkham Croo 1970 and Tuckerman Ravine 1971)  by devoting countless hours helping to organize and operate several rail trail organizations, including Assabet River Rail Trail as well as Nowottuck Network, Inc. He worked tirelessly for the Old Hutcroo Association, an alumni group of AMC employees; serving on their Steering Committee as well as being their first Webmaster/Webhost. He attended many of their reunions and loved his time in the White Mountains of New Hampshire.

Tom’s survivors include his parents, Peter and Marie Kelleher of Peabody; his brother Michael and his wife Lynne of West Dover VT; his sister Ann Kelleher Lamond and her husband John Lamond of Plymouth; and his nephews and nieces, David Lamond and his wife Holly of Chantilly VA, Matthew Kelleher and his wife Gabriela of South Boston, Maggie Lamond of Austin TX, and Amy Kelleher Royer and her husband Brad of Newburyport.

Additional joy for Tom was the birth in recent years of his grandnephews Charlie and Jack Kelleher of South Boston.

A memorial service for Tom will be conducted at the Acton Funeral Home, 470 Massachusetts Ave. Acton at 1:00 P.M. on Saturday, January 14th, and subsequent burial at the Cemetery of the Holy Cross in Franklin, New Hampshire – long known to be Tom’s second favorite state.
