When a career change relocated Sweet Farm co-founders, Anna Sweet & Nate Salpeter, from Seattle to the Bay Area - they fulfilled their dream of buying land and dedicating it to the pursuit of ending inhumane factory farming practices. Both long time animal advocates and volunteers at local rescues, they wanted to find a way to maximize their impact and educate people on how to live more compassionate and sustainable lives. The couple still works full time in tech, but dedicates evenings and weekends to working with the animals of Sweet Farm and helping spread our message.
