Looking for internship, volunteer position, or part-time job

#1
Hi everyone,
I'll be in Argentina as of June 6th, until July 12th. I'm looking for an internship with a health consulting group, NGO, or non-profit. I studied biology as an undergrad and will begin graduate school for a Master's in Public Health in the Fall. I'm interested in possibly volunteering or interning with a family planning program or health promotion program. Does anyone have any suggestions? Thanks!
