Medical Relief Trip to Costa Rica

I am part of a medical relief team that will be traveling to Costa Rica this spring to provide medical care at local clinics in the San Jose and Puntarenas areas. For 9 days I will be volunteering in multiple clinics, helping physicians diagnose and treat the Costa Rican natives. Many of the cities I will be visiting are very impoverished and lacking a sufficient healthcare system, therefore the locals are heavily dependent on volunteers such as myself when it comes to maintaining their health. Any way that you can contribute is immensely appreciated, as it will cost each student nearly $3,000 in travel, room, and board. Thank you so much!!
