HELP is a lean and transparent organization that is focused on providing help to Nepali and Indian institutions with a minimum of bureaucratic froufrou. In Nepal, I met volunteers working through other organizations, and they were astounded at the minimum fuss and money that volunteering through HELP entailed. I found HELP though an Internet search. They looked like the best organization through which to volunteer, and I now believe they are the best.
