Hadassah is the co-founder and executive director of Tikkun Olam Farm Sanctuary, a forever home for abused, abandoned, neglected, and unwanted farm animals. She is vegan and has spent nearly two decades as an activist in the animal rights movement. She spent many years working in the veterinary field running a surgical department, a medical hospital at a no-kill animal shelter, and doing wildlife rehabilitation. She obtained her graduate degree in Holocaust and Genocide Studies with a focus on psychology from West Chester University, and she spent ten years teaching college students in her home state of Delaware. When she moved to Oregon in 2013, she decided to merge her love of animals, education, and Judaism to begin the only Jewish farm animal sanctuary in the country where over 130 animals are living their best lives.
