Mario Fernando Costa

Mario Fernando Costa – Methuen, MA

Mario Fernando Costa, 69, of Methuen, Massachusetts, passed away peacefully at home on January 28, 2026, surrounded by loved ones, after a courageous battle with cancer. Born on March 23, 1956, in Faial, Portugal, Mario lived a life defined by devotion to his family, a deep love of learning, and a generous spirit that touched everyone he met.

Mario brought light, warmth, and joy into the lives of his family and friends. He shared 50 beautiful years of marriage with his beloved wife, Emilia Costa, and together they built a home filled with love, laughter, and strong values. His legacy continues through his cherished daughter, Liane Costa, and his adoring grandchildren, Gavyn, Ayva, Karsyn, Dymario, and Gyanni, who were the pride and joy of his life.

He was preceded in death by his daughters, Marlene Diodati and Tania Costa; his father, Manuel Costa; and his brother, Humberto Costa.

Mario is survived by his loving mother, Germana Costa; his brother Ilidio Costa and his wife Teresa; his brother Jose Costa; his sister, Helia Costa; his aunt,  Lucilia Duarte; and many dear nephews, nieces, cousins, and lifelong friends.

Educated in both Faial and the United States, Mario carried a lifelong passion for learning that he applied to every aspect of his life. He was the proud self-employed proprietor of Costa Heating, where he worked as a skilled plumber and built genuine, lasting relationships with his clients and tenants through honesty, care, and dedication.

A devoted Catholic, Mario was a man of many interests and simple joys. He loved fishing, especially with his family, barbecuing, landscaping, and took pride in maintaining his properties. He was known as a great pool player, a true handyman who could fix anything and someone who worked tirelessly while forming meaningful relationships wherever he went. He also enjoyed relaxing with a good cigar and a glass of wine, appreciating life’s quiet pleasures. Winston, his dog, was his faithful and loyal companion.

Mario Fernando Costa will be remembered for his strength, kindness, generosity, and the love he gave to his family. He will be deeply missed and remembered dearly by all who knew him.
