What started out as bringing home a new pet donkey turned into a passion project for Mark Meyers and his wife, Amy. Mark learned that donkeys are a very misunderstood and often abused animal. He started rescuing donkeys in his area, giving them medical care and connecting them to forever homes. In 2000, he founded Peaceful Valley Donkey Rescue, which has become the largest donkey rescue in the world and has helped more than 13,000 donkeys to date.
