I am also a 23 year old male, currently in the middle of my first year of PA school. I chose to go to PA school for similar reasons as your son, and because I don't care about prestige, money, or being in total control. Just want to make a difference and help patients. However, I know a lot of people these days are paying well over 100k just to attend PA school in the first place. Luckily, I go to an instate program where the total cost is under 40k. Need to consider the amount of debt for school as well, he might as well consider med school if he is going to be paying the same price for it.
