Meet Our Leadership Team

Open Door Animal Sanctuary is staffed by a lean and mean team of three executive staff, an office manager, a community engagement/volunteer coordinator, two office staff, a (dog) kennel manager and assistant, a cattery manager and assistant, three vet techs, three part-time veterinarians, and a group of kennel and cattery staff and volunteers who spend 100% of their time caring for our nearly 400 dogs and cats every day.  Each uses their unique talents and love of animals to provide the best quality of life for our residents.
