John Turnbull forced me to step out of my comfort zone in order to explore what it means to be more than just [a] good writer. … For the first time since coming to NIU, I felt like I was learning as a writer. … I was finally receiving actual, in-depth reviews of my writing.

I can’t thank John enough with teaching our son and getting him caught up with writing and vocabulary. I highly recommend him for any child who needs help in English, writing, and/or vocabulary.
