Gregory Arthur Sullivan, 77, of Westcliffe, Colorado, passed away January 3, 2025, in Pueblo at the nursing facility Rock Canyon Rehab & Respiratory Center, while surrounded by his daughters, Brianna and Casey Sullivan.
He was born in Los Angeles, California, in 1947 to John Lawrence and Jean (Bina Masten) Sullivan. Greg attended Holy Family Catholic School as a child followed by South Pasadena High School. He then went on to attend Pasadena Community College and University of California – Berkeley earning his Bachelor’s in Police Sciences, Masters in Criminology, Masters/Doctorate for Investigative Sciences, as well as a Bachelor’s in Business. Overall he spent eight years beyond high school educating himself. He was a firm believer in “Knowledge is the one thing they can never take away from you. It’s priceless.” He showed this philosophy through his deep and lasting connections with everyone he met, no matter where in the world they were or what language they spoke.
Before settling in the Wet Mountain Valley with his daughters and volunteering as a posse member for many years, Greg was an avid traveler in his days. He went to many places such as: Egypt, Turkey, Spain, England, Ireland, Scotland, Mexico and beyond. With his father, John being his best friend, he showed him the ropes of Europe during many trips together, including kissing the stone of Blarney; evermore certifying and granting him the gift of eloquence.
