We are a nonprofit organization dedicated to providing free medical equipment and supplies to those in need! PMHDC Southwest Medical Aid (PSMA) is dedicated to providing durable medical equipment and medical supplies free of charge to other qualified charitable organizations, for their clientele, who may otherwise go without. Our supplies come from excess inventory at hospitals, private practitioners and individuals. Donated medical supplies and equipment are primarily distributed through a network of nonprofits, hospitals, clinics and agencies in Arizona, as well as in Sonora, Mexico, with occasional shipments internationally. We provide over 100,000 pounds of medical equipment and supplies annually.
