All proceeds will benefit a special clinic for first responders affected by trauma. The clinic will be conducted at a future date at no cost to first responders. The Amity Foundation offers equine-assisted therapy to people who have experienced trauma from Veterans to PTSD to sexual abuse survivors with recurrent memories.
