Veterans have the option of using their Post-9/11 GI Bill to cover costs for courses such as dive instructor certification. One organization that offers such courses for veterans is Ocean Deep, a veteran-owned business. For more details, link to the Ocean Deep website. Diving can help with conditions such as PTSD.
