Switching Careers from EHS

I was considering a career switch from EHS (Environmental Health and Safety) to likely a PA program. I already know for a fact I'll have to take a few more classes (Just 1-2 biology classes as I was Pre-Med before switching to safety). I was wondering if anyone on here has switched over from this sort of field to a medical field, thoughts on the transition process, tips, etc. thanks!
