Chief Mission Officer
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. 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 her time at No More Homeless Pets in Utah, she created and implemented some of the first comprehensive targeted community cat public-private partnerships with Utah shelters. In 2010, Holly took a national role at Best Friends Animal Society and has provided leadership support and stewarded growth in these areas: sanctuary animal care; legislation and advocacy; the Best Friends Network; community cat programs; embed, mentorship and training programs; business intelligence; and puppy mill, cat and pit bull initiatives. In her current role as Chief Mission Officer, Holly oversees all Best Friends’ outreach programs outside of the sanctuary and is a member of the senior leadership team. Holly’s leadership has focused on growing and improving many of the programs created as part of No More Homeless Pets in Utah. The shelter-focused community cat programs have evolved into one of the most effective, efficient and transformational tools in the journey toward achieving no-kill nationwide, and Holly is most proud of seeing how this model is growing exponentially throughout the U.S. Holly holds a bachelor of fine arts degree from the University of Utah and a master of public administration degree from the University of Washington. She and her husband proudly share their home with a few former community cats and two adopted dogs. Holly believes we will achieve our common goal of making the country no-kill by 2025 through the right balance of warrior resolve, patient persistence and true collaboration.
