Louis “Kevin” Callahan

October 2, 1957 – November 6, 2025 Born in Baltimore, Maryland • Passed in Joppa, Maryland

Louis “Kevin” Callahan, 68, of Joppa, Maryland, passed away peacefully at home, surrounded by the love of his family.

Born on October 2, 1957 in Baltimore, Kevin was the son of the late John Francis Callahan, Sr. and Dorothy Helen Callahan. He proudly served his country as a Lance Corporal in the United States Marine Corps, carrying the discipline and dedication of a Marine into every part of his life.

After graduating from Bel Air High School, Kevin built a successful career as a Commercial Development Executive in the Baltimore area, where he was respected for his integrity, sharp wit, and easy rapport with everyone he met. Kevin never met a stranger or an animal that didn’t love him. His unwavering kindness left a mark on everyone fortunate enough to know him.

He spent countless summer days on the water, sharing his love of boating, tubing, and fishing with family and friends. Known for his legendary crab feasts and spectacular Fourth of July fireworks — Kevin made every gathering feel like a celebration.

Kevin shared 42 years of marriage with his wife, Diane Callahan. He is survived by his beloved children Eric Gresham and wife Kate, his daughter Kate Callahan, and daughter Tracy Becker and husband Edward, as well as his cherished granddaughter, Lilly Gresham, who brought him endless joy.

Kevin is also survived by his siblings Colleen Callahan Freeman, Thomas Callahan, Anne Pesto, and Laura Callahan, and was preceded in death by his brother John F. Callahan, Jr. He will be fondly remembered by his nieces and nephews Elizabeth Freeman Wiley, Habern Dean Freeman Sr., Kate Freeman, Christopher Pesto, Jennifer Pesto, and Noah Mezan — and by the many dogs, cats, and other animals that surely ran to greet him in heaven.

A gathering of family and friends will be held on November 20 at 10:00 a.m. at McComas Funeral Home, 1317 Cokesbury Road, Abingdon, Maryland. A memorial service will follow at 11:00 a.m., after which there will be a procession to Gardens of Faith Memorial Gardens, 4419 Kenwood Avenue, Baltimore, Maryland. A celebration of life will be held afterward, with details to be announced.

In lieu of flowers, donations may be made to the American Cancer Society or to the Baltimore Animal Rescue and Care Shelter (BARCS) in Kevin’s memory.
