Sheridan Funeral Home
July 7, 1955 - January 22, 2026
Phillip Douglas Gilmore, 70, passed away in his home on Thursday, January 22,
surrounded by his loving family.Phil was born to Bruce and Audrey Gilmore and
grew up in their home in Alberton, Montana. He was the fourth of six children.
He developed his lifelong love of the outdoors early on and wasn't afraid to
venture out alone, even in less-than-ideal conditions. As an Eagle Scout, he
completed his solo 50-mile hike while suffering from a fever.
Phil attended Montana State University for a year before he decided to join the
Navy. He bought a motorcycle and drove halfway across the country to serve for
four years. Afterwards, he returned to college. He graduated in 1982, earning a
degree in construction engineering.
Phil met his wife of forty-one years, Janelle Gray, while working at the Hunter
Ranger Station outside of Buffalo. The couple always wanted to be parents, first
hosting a foreign exchange student from Sweden, Thorbjorn, before staying in
Peru and Guatemala to adopt their children Brenna and Ben. A few years later,
they were surprised by a biological child, Maya.
Phil and Janelle prioritized travel throughout their lives. Almost every summer,
the family camped in the Big Horn Mountains or traveled to some corner of the
U.S. or even visited overseas.
Phil was a co-owner of Landon's Greenhouse for over two decades with Janelle and
her brother, Wayne. He created landscape designs, led the landscape crew, and
dug holes with his own two hands. He planted countless gardens throughout
Sheridan, literally reshaping the town's landscape—to say nothing of the
handiwork he put into his own home. There is no telling how many places and
people his quiet leadership, hard work, and creativity touched.
He was a mentor, friend, and father figure to many people around him, always
happy to just listen, to lend a hand, or to offer advice. From investing to
construction to fly fishing, he had good advice about many subjects.
Phil was a beloved member of the Sheridan Unitarian Universalist Fellowship for
many years. He was a major advocate for finding a permanent home for the
fellowship. Once a building was purchased, he spearheaded the remodel, visiting
almost every day for two months to organize volunteers.
Despite a years-long struggle with cancer, he was a problem-solver and a
thoughtful, generous person until the end.
Phil is preceded in death by his parents, Bruce and Audrey Gilmore, and his
wife, Janelle Gray. He is survived by his children Brenna Montagne (Danny),
Benjamin Gilmore, and Maya Gilmore, and his grandchildren Madix, Eliana, and
Malakai Montagne, as well as siblings Pamela Cole (Timothy), Gregory Gilmore,
Winona Forme (Steve), Russell Gilmore (Peggy), Melissa Gilmore (Todd), their
children, and many beloved friends.
A celebration of life ceremony will be held in early March. More details will be
announced soon.
