Is it possible to branch medical when commissioning with a degree in Kinesiology?

When you commission through OCS you will get whatever branch you're given during the branching process

Try the Air Force at Wright Patrick AFB . You're going to need a PhD though to make any headway among those Brainiacs.

Med services is not available at all through OCS, or at least it wasn't when I went through this year (graduated in May 2019). Also, if it is, you can submit a packet for it and if PLT mentors and command accept it you can get it without having to worry as much about the OML (order of merit list). I doubt it's available but I've heard certain branch choices come and go depending on the cycle. I'd ask your recruiting office to contact OCS and find out for you if Med Services is available at all.
