Ask the lady how many pro fighters does she teach, or how many fights the instructors have.
(You can't be a kickboxing or boxing instructor if you have never kickboxed, or boxed, and don't have any students that have).
A "little bit of wrestling" sounds like a whole lot of junk. This seems more like someone trying to capitalize on MMA. I am betting the lady is also a personal trainer (kings and queens of self promotion and commercialization), and most of their stuff is cardio kickboxing/boxing with some little crap thrown in, to make it seem like you are learning something.
Ask her how much they spar, how often do they do full contact, how often do they "roll" or wrestle. Ask for her credentials. I am betting she has some rank in TKD, and then some other made up type of art, like Upkudo or something. "touching" on karate, tkd, boxing and kickboxing, sounds pretty shady to me.
I think you are better off driving the 60 miles to check out a Judo club or Jujutsu, or Jiu-Jitsu (if it is spelled that way it should be BJJ), and maybe a Karate dojo.
It sounds harsh, but studying crap only reinforces bad habits that you will one day have to unlearn (if you ever want to fight at even an amateur level) and having a little bit of wrestling, doesn't prep you for ground work or dealing with submissions... in fact what does that even mean? Is anyone of them a former D1 or D1A College wrestler? Who is teaching what is what i would find out, and what are their qualifications to teach it.
Better to take the drive and spend the money on a real instructor, then help fund a total fraud. It might be closer, but if it is a waste of time, you are better off driving in my honest opinion.
