Stand Down events are crucial initiatives designed to help traumatized Veterans overcome homelessness and reintegrate into society. These three-day gatherings provide essential medical, dental, and legal services, but their primary impact lies in restoring a vital sense of community. Founder Dr. John Natchison aptly describes them as a "drug-free Woodstock combined with Maslow's hierarchy of needs and a family picnic."

With over 300 events across the U.S., Stand Down mobilizes 2,000 volunteers to welcome 1,000 Veterans at each session. Recognizing that Veterans disproportionately experience trauma, PTSD, substance abuse, and homelessness, these events foster the community and connection necessary for them to recover their purpose and passion.
