Cliff Cullen, Deputy Director

Cliff was born and raised in the Florida Keys where he grew up surrounded by animals, both wild and domestic. This instilled a deep love of all animals from a young age. He moved to Colorado in 2018 after several years in Southern California. He has over 10 years of fundraising experience and is excited to apply this experience in helping LHS fulfill its mission. He lives in Longmont with his wife, Marjorie, and their cat, Juniper, who came to their family from LHS in December of 2021.
