John Irish is verifiably one of the top 5 educators in the country. That's not just me saying it. College Board selected him as one of 3 teachers to help rewrite the AP US History exam, and he was selected as the co-chair of that committee. He reads for the AP exam every year and spends his summers traveling around the southern US teaching other APUSH teacher how to teach the subject. I was lucky enough to get him to sit down with me, mostly because he was avoiding grading papers.
