Tanzania Medical Volunteer

Hi friends and family! I will be spending 3 months volunteering at a  medical clinic in a town called Manyoni in Tanzania, Africa. I will be leaving on September 1st and coming back December 1st. This is an amazing opportunity for me to gain medical experience from a different perspective. The people that I will be staying with are very generous as they are housing me and I would like to leave them with a donation of some kind. I dont know much about the type of medical supplies that they have currently, but I will be posting updates as I learn more. My aunt lived there for a year and was able to raise enough money to buy the clinic an ultra sound machine. I would like to do something similiar. Any amount would be amazing, I just want to leave the clinic and organization a gift of some sort. Thank you!
