I know I just got here, but today I really felt the push to start figuring out my next step because these things take time.
I was looking a the mission medic partners and sent an email to Compasio about volunteering short term like over the summer. If you are curious about what they do here is the link to their site.

I have always wanted to go to Thailand and would love to be a part of what God is doing there. :]
