Poliquin, Staley, Thibadeau, and Waterbury all have master's degrees (or are working toward there masters), that kind of answers your higher education level question now doesn't?
The best business advice I have received came from Charles Poliquin: "The basic rule is that you have to read 10 hours a week on a particular topic for five years to develop an appreciably level of expertise on that precise subject. If you're not willing to commit that much time, you might consider a different line of work."
This field does not need any more piss pore strength coaches/trainers. Utilize every means you have to gain knowledge, you could intern, read books, read articles, watch training videos, call and/or e-mail other strength coaches, those are just a few of the paths to gain knowledge.
Knowledge is not power applied knowledge is power!
