Volunteer Trip to Costa Rica

The program I am interested in volunteering for is based in Costa Rica. I will be assisting a medical doctor as they visit patients in their homes for two weeks.
I have received a scholarship for 30% of the total cost of this trip already, but because I want to raise money for the trip myself, I chose to fundraise for the remaining amount. I have until mid-June to raise the money I need for this trip. I am going to use the experience of this trip as my Senior Project, and through it teach students and Boulder residents who view my presentation, about the healthcare needs and situations in Costa Rica. 
After high school I want to enter a pre-med program so I can study to become a doctor. Through this program, I will be spending time helping Costa Rican families through volunteer work, and providing healthcare to the people that need it. This is an amazing, life-changing opportunity for me, and as a future doctor, this will give me insight into what healthcare is like in other countries. This is my first time leaving the country, and to work with people in this program will give me a real-world experience on what it means to be a doctor. Please help me to reach my goal and begin my journey to becoming a doctor so I can help even more people in more meaningful ways!
