Healthcare Management Summer Program

Hi CC,
I am currently a high school junior interested in choosing healthcare management as my intended major, and my top choices are UPenn Wharton and Wash U Olin for that particular major. However, I was wondering if there were any summer programs out there that could help me build a stronger application for HCM. Let me know if there are any summer programs for healthcare that you would recommend. I am already applying to Wharton’s LBW program. If it matters, my GPA is a 3.87 UW and a 3.96 W, and my ACT score is a 34.
Thanks
