At your link, his students rip him to shreds! Hysterical!
The consistently bad reviews over eight years is more an indictment of the school’s governance than this particular clearly wretched faculty member. If he behaved like this during his probationary period, he should have been fired. If not, and he ‘slipped by’ until he had tenure, he has clearly ‘retired on the job’.
Not just this professor, but any school that collects tuition and harbors faculty like this should be avoided. Some good advice on optimizing the funds expended on acquiring a credential used to be posted for free, now it has apparently gotten enough traction that the author took down the site and sells the material as a “manual” : http://www.garynorth.com/public/729.cfm .
After reading all of that, it is scarey this that this crazy professor is running around with a box-cutter.
