On May 13, 1989, Michael married his loving wife, Denise Anne Cioll, at St. Matthias Church in New Orleans, officiated by his uncle, Monsignor Raymond Wegmann. They shared a wonderful 36 years together, traveling the world and creating lasting memories with family and friends. Michael was immensely proud of his daughters, Megan Louise Glennon and Shannon Joan Glennon, both of whom graduated from medical school and began their residencies with their father by their side.

Michael had a deep love for golf, the New Orleans Saints, Tulane and LSU football, New Orleans cuisine, old tv shows and movies, The Beetles, and most of all his family and friends.
