Careers and how to get there?

Hi! My son had a very rare seizure disorder that came on fast and furious when he was 2.5. Long story short, he was on 7 medications, built up toxic levels on one, lost all of his speech, couldn't walk. We were told he'd "never be normal". We put him on a Ketogenic Diet and within a month his 30 t/c seizures a day were gone. He's now 8 and off all meds and as of last year, he is also off the diet. Needless to say, I believe in the power of alternative therapies. I am only in nursing school and have a long road ahead of me, but would love more information about holistic nursing - what types of jobs are out there? How do you specialize? Is there anything I can do now that would help me down the road? Thanks so much!
