David A. Montagna

David Augustine Montagna, of Waltham, died Tuesday, February 3, 2026 at Mount Auburn Hospital in Cambridge. He was 74.

David was born in Waltham on September 23, 1951, son of the late Augustine and Lorraine (Gorham) Montagna. Raised and educated in Waltham, he graduated from Waltham High School.

For many years, David worked as a skilled mason, following in his father’s footsteps at the family business, A. Montagna & Son. Together, they crafted immaculate brickwork.

David married Ann Marie O’Connor on October 5, 1996 at Sacred Heart Church in Roslindale, beginning a partnership that lasted nearly three decades. Known for his kind heart and gentle spirit, David always made time for others, often sharing a cup of coffee and conversation with friends and family.

An outdoors enthusiast with a deep love for animals, David grew up with dogs and cats as pets. He enjoyed trips to Maine for fishing, walks in the woods, and tracking wildlife. A car aficionado, he owned a Corvette and liked drag racing in New Hampshire winning many trophies. His adventurous side took him to Hawaii, St. John in the U.S. Virgin Islands, and St. Lucia. In a memorable solo trip, he drove cross-country to California and back, taking in the open road.

David was predeceased by his sisters, Brenda Rogers and Debra Cotoni.

He leaves his wife, Ann Marie (O’Connor) Montagna; his sister, Phyllis Mahoney, and her husband, Stephen, of Burlington; his brother-in-law, Paul Cotoni, of Cape Coral, Florida; his in-laws, late mother and father-in-laws Mary Ann and Marty O’Connor, Patrick O’Connor (Josephine) of Weymouth, Noreen Sheehan (Kenny) of Marshfield, coffee loving buddy Betty Sheehan of Marshfield, and Donald Dean (husband of the late Mary Ellen) of Mansfield; his nieces and nephews, Debra Patuto (Jeffrey) of Danvers, Jeffrey Mahoney (Mira) of Helsinki, Finland, Allison Skaling (Daniel) of Cape Coral, Paul Cotoni (Christine) of Cape Coral, Charlene Smith (Michael) of Cape Coral, Brianna Abbene (Gregg) of Huntington, New York, and Mark Rogers of Ayer, Sean O’Connor (Cassie) of East Boston, Mark O’Connor (Adele) of Rehoboth, Jacqueline O’Connor of Weymouth, Mason Dean and Patrick Dean of Mansfield, Shannon Dean of Fall River, and Marianne Sheehan and David Sheehan of Marshfield; and many grand-nieces and grand-nephews.
