September 1, 1953 – December 31, 2025
With heavy hearts, the family of Dr. Gregg MacLean, beloved husband of Jo (Brazel) MacLean, announce his unexpected passing, which occurred on December 31, 2025, at the Saint John Regional Hospital. Born September 1, 1953, he was a son of the late Stan and Helen (Lamont) MacLean.
Above all else, Gregg was devoted to his wife, Jo. Married for 47 years, they shared a partnership defined by love, loyalty, and unwavering support. They did everything together and were rarely apart. Jo supported Gregg throughout his career and life’s many endeavours, and in return, he took immense care of her. Their relationship was the foundation of their family and a model of deep commitment and mutual respect.
Gregg was also a deeply devoted father to his son, Mark. While he spent much of Mark’s childhood at the hospital balancing the demands of his medical career, Gregg was intentional in sharing what mattered most to him. He passed along his love of music, introduced Mark to the wider world through travel, and shared traditions that strengthened their bond. One such tradition was an annual “hockey trip” along with Gregg’s classmates – time together that Gregg valued and never missed.
Gregg was a dedicated family man who found great joy in time spent with those he loved, especially his grandchildren. Whether attending soccer practices or faithfully making the same much-requested meals, he showed up with consistency, patience, and love. He was extremely generous with his time and attention, and his sense of humour — including his spot-on impersonations — kept his family and friends laughing.
Gregg was an entertainer at heart and had played in a band, singing and playing multiple instruments. He enjoyed sharing his deep appreciation for music as well as golfing with friends, reading, cooking and travelling. As avid travellers, Gregg and Jo explored destinations all over the world; in recent years, their favourite trips were those spent taking their grandchildren to Disney World, creating memories he treasured deeply.
Recently, Gregg fulfilled a dream with the completion of a family cottage in French River PEI, a project made possible with enormous help from his brothers. He was grateful to be able to see it completed and to experience a short time there with his family before his passing.
Professionally, Gregg was a highly respected neurologist who practiced in New Brunswick for more than three decades, beginning in 1989. Gregg and Jo were heavily involved in planning reunions for his Dalhousie Medical School Class of 1984, valuing lifelong friendships and connection with his colleagues.
Gregg was instrumental in establishing New Brunswick’s first Multiple Sclerosis Clinic in Saint John and was a key figure in advancing MS care in the province, including supporting innovative treatments. He also played a crucial role in the development and launch of the Telestroke system in New Brunswick, significantly improving access to timely stroke care across the province. To no one’s surprise, Gregg was awarded the New Brunswick Medical Society Order of Merit in 2025 in recognition of his outstanding commitment, leadership, and service to the medical profession.
Gregg’s family is immeasurably proud of him – for his dedication, his generosity, his unwavering support, and steady presence. He was a man deeply loved by all who knew him.
In addition to his wife of 47 years, Jo, Gregg is survived by his son, Mark MacLean (Catherine); grandchildren: Joshua and Halle; his siblings: Barry (Vera), Kevin (Ermelinda), Garth (Ann), Heather Mountain (Horace), and Ron (Irene); his aunts, an uncle, and several nieces, nephews, and cousins.
Besides his parents, Gregg was predeceased by his sister, Faye MacLean.
Arrangements are under the care and direction of Brenan’s Funeral Home, 111 Paradise Row, Saint John, NB (506-634-7424). Family will receive visitors at the funeral home on Wednesday, January 7, 2026, from 1 to 4 and 6 to 8 pm. A Celebration of Life will be held at The Union Club on Thursday, January 8, 2026, from 4 to 9 pm. Burial will take place in PEI at a later date.
For those who wish, remembrances made to the Heart and Stroke Foundation of New Brunswick would be appreciated by the family.
