I volunteered for one month at the prosthetic clinic in La Paz. The clinic provides free or inexpensive prosthetics to those who cannot afford them. It is one of the best volunteer experiences that I have had and one of the best experiences of my life. The center provides opportunities for so many people: amputees and their families, local businesses, and volunteers from all over the world. Many amputees have no chance of affording a USD3,000 to 5,000 prosthetic from other clinics, but because of the Centro, they can hope to walk again. The Centro sources all possible materials from Bolivia, supporting local vendors. Volunteers have the opportunity to work in an amazingly large variety of fields as compared with other organizations. They can help write grants, create videos, or work hands on with prosthetic technicians to help build prosthetic limbs.
The Spanish in La Paz can be considered the most neutral accent so is a great place to learn or improve Spanish as a second language. La Paz can also be used as a base camp for exploring the altiplano area of Bolivia, although you may not want to leave after being a part of the clinic.
