Gregory 2019 photoOne of the founders of Best Friends Animal Society, Gregory Castle served as CEO of Best Friends from 2009 to 2018. Since stepping down from being CEO he continues to work for Best Friends on fund raising and special projects, with the title CEO Emeritus. When not working at the Sanctuary, and when he can tear himself away from his two dogs and three cats, he travels throughout the country and occasionally abroad addressing conferences and networking with organizations and individuals on animal welfare issues such as improving save rates, resolving community cat issues, developing coalitions and working with government to help the animals.

Gregory created No More Homeless Pets in Utah, a campaign involving animal welfare and rescue organizations, animal control officers, veterinarians, schools, and animal lovers from across the state in robust spay/neuter, adoption, and public awareness programs.

High on the list of Gregory's favorite spare time activities are long distance running and hiking in the beautiful red rock canyons of S. Utah. Among his 21 marathons and ultra races are three Boston marathons, occasions he describes as memorable. Gregory grew up in England and is a graduate of Cambridge University with a master’s degree in philosophy and psychology. His background includes extensive administrative and accounting work for nonprofit human services and church organizations.
