I am looking for an MBA in general management/operations/consulting.

I am currently thinking about applying to UC Berkeley’s part time program mostly due to the amount of loans I already owe and because of the loss of wages if I were to go full time.

Goals:
Continue to move up the health care management ladder
Move into operations in biotech/pharm
Health care/management consulting

My primary reasons for considering an MBA are:
I really enjoy my job right now, more so than being a “physical therapist” where I treat patients 100% of the time. I view myself as a physical therapist in a management role not necessarily a health care manager. I know this may not be the case but on paper that’s what it may come across. Why this is relevant and why it concerns me, is that I would like to continue moving up the health care ladder or in the near future transition into biotech of pharm. Consulting is also an area I would like to get into eventually. I am concerned that my resume/education background may hold me back.

My questions are:
1) Do I even need the degree or can I supplement my resume with other leadership/management courses/extracurriculars? Sometimes I think my age prohibits me from gaining the full benefit of an MBA at this stage of my career. I have heard from others that I do not need the degree so would an MBA help me?
2) Does it even make sense going back to school given the amount of loans I already owe-think high 
3) If I do go back to school, full time or part time?
4) Worst case scenario -If I wanted to transition into a different but related industry (biotech/pharm) should I just work at getting my foot into the door and work my way up again?

Thanks for your time, I really appreciate it
