We at PRA (Park Rx America) believe that nature-rich areas should be accessible to all, and incorporated into our daily routines. Spending time in and around nature is the single most important first-step to improving both human and planetary health. PRA is committed to educating healthcare professionals and the public, and to providing the tools to meet each individual's unique needs.
