Interesting - they show outcomes on the webpage and the first two are consulting, but not your strategy type. They also have business analysts and the requisite Teach for America. But no defined curriculum - but note it includes quant, teamwork, and then what a student designs - so almost like a self designed major.
It’s easy for anyone, including parents, to say this is better or that is better. My daughter is majoring in International Studies (with a Chinese focus) and has to add a second major but it will likely be as un pre-professional - maybe sociology, etc.
In the end, while I’d love for her (or even me) to be an engineer or accountant, etc. you have to pursue academically and then professionally what you are passionate about. I was a broadcast major and since Syracuse knew most would not succeed, they required a 2nd major - so I did History - and I survived.
If he’s passionate about this and I hope he is vs. a career counselor said it’s the way to go -well, all we can do is love them and support them - right 
I do think if he wants your McKinsey, Bain, BCG, etc. just looking at the outcomes, perhaps this isn’t right - because they are snobs both in school and major.
But - he’s going to create a path for himself - consulting or otherwise and it will be a fun ride.
How does one find / acquire a career coach?? I’m more interested in that
