On October 2nd, 2025, Dennis "Denny" Michael Flynn, Sr., beloved husband of the late Margaret "Peggy" Flynn (nee Holtzman), devoted father of Lisa Anne Flynn, Patricia Leigh Flynn, and Dennis Michael Flynn, Jr., and Suzanne Elizabeth Fisher, dear brother of Elizabeth Benton, Deborah Chenoweth, and the late Brian McColgan. Grandfather of Matthew Edward Flynn, Logan Elizabeth Kruhm, Alex Ryan Flynn, Rylie Paige Kruhm, Sean Michael Flynn, and Delaney Grace Kruhm.

Denny was proud of the years he spent as an analyst at NSA, though he always maintained he "couldn't talk about" any details of his work. He was an avid boater on his beloved multi-hull sailboat Fenian. He enjoyed spending time with his friends and playing in softball leagues. He was always up for a debate on things he was passionate about and would rarely acquiesce any position he held.

The family will receive friends on Friday, October 10th, 2025, 4-7PM at the family-owned Ruck-Towson Funeral Home, Inc., 1050 York Road (beltway exit 26).
