Holly Sizemore

Chief Mission Officer

Best Friends Animal Society

Holly Sizemore entered the animal welfare world in 1991 when she discovered a colony of community cats eating near a restaurant dumpster. The experience inspired her to co-found the first trap-neuter-return (TNR) organization in Utah, the Community Animal Welfare Society (CAWS) in Salt Lake City, and she was a co-leader of that organization as a volunteer for about 10 years.In 2000, Holly joined No More Homeless Pets in Utah and served the organization in a variety of roles, ending with executive director from 2007 to 2010. During that time, she created and implemented some of the first comprehensive, targeted community cat public-private partnerships with Utah municipal shelters.In 2010, Holly took a national role at Best Friends Animal Society and currently serves as chief mission officer. She has provided leadership support and stewarded growth in a number of areas including the Best Friends Animal Sanctuary, national outreach programing, data and program analytics, as well as legislation and advocacy.Holly holds a bachelor's degree in fine arts from the University of Utah and a master's degree in public administration from the University of Washington. She and her husband share their home with a few former community cats and one adopted dog. Holly believes that we will achieve our common goal of achieving no-kill nationwide by 2025 through the right balance of warrior resolve, patient persistence and true collaboration.
