Dan Leary

Leary, Daniel J., age 77, a resident of Royal Oak for over 50 years, passed away peacefully in hospice care February 10, 2026. He was born August 28, 1948 Buffalo, New York, to the late George and Eileen Leary. Dan grew up in Buffalo but moved to attend the University of Detroit from where he graduated both with a Bachelor’s and a Master’s degree in 1971 in Electrical Engineering. He also earned an MBA from Michigan State University in 1977. Dan was a member of Sigma Phi Epsilon while he was at U of D and enjoyed the many friendships and activities it afforded him. Following his graduation from U of D, Dan worked at the Burroughs Corporation in midtown Detroit for ten years. He then co-founded Automated Programming Technologies (APT), located in Bingham Farms, and remained there for 15 years. After he “retired” from APT Dan went on to teach finance classes at Walsh College in Troy for several years. He valued all the aspects of his varied career and committed himself wholeheartedly to any project presented to him. Dan met his one true love and life partner, Mary Dwyer, while at U of D and would have celebrated their 50th wedding anniversary this October. Mary and Dan were rarely apart, sharing many common interests including golf, traveling, watching the Tigers and Lions, and playing cards with friends. Perhaps their fondest memories are of their numerous trips to their condo at Crystal Mountain over the past 35 years. Dan also was a member of Queen of Martyrs parish in Beverly Hills for 49 years. Dan is survived by his devoted wife, Mary; his sisters Noreen Finn (Jim, deceased) and Sharon Leavitt (Mark); and sister-in-law, Patricia Dwyer. He was the cherished uncle of Mary Janisse (Jeff), Peggy Finn (Autumn Richardson), and Beth Tavano (Matt). His great-nephews Liam Janisse and Will Tavano also mourn his passing. Visitation will be held on Friday, February 13th, 4 - 7 pm (Rosary 3:30 pm) at Wm. Sullivan & Son Funeral Directors, 705 W. 11 Mile Road (4 blks. E. of Woodward), Royal Oak. The Funeral Mass for Dan will be celebrated on Saturday, February 14th, 10 am (in-state 9:30 am) at Our Lady Queen of Martyrs Catholic Church, 32340 Pierce Street, Beverly Hills.
