I've had internships each of the last two summers. One was in health promotion at OSU's Student Health Services and the other was at Oregon Health Sciences University in Portland. In Portland I prepared a resource guide for incoming diverse students. I did a lot of research and put it together. It was a great experience.
Internships are a great way to meet people and build relationships for the future.
I'd tell new students to set high goals and really challenge themselves. That will be valuable when you get to college.
