I went to Mt. SAC, and Steve is semi-retired last time I heard. He's no longer the program director, and only handles the pre-course and some of the early lectures in the program now. I'm sure he'll be completely retired in the near future.
Regarding the program itself; yes, it is very challenging. The vast majority of students fail the first time through, but the reason for this is Mt. SAC hits anatomy & physiology really hard...like much harder than any undergraduate level course. The second reason for the high fail-rate is there isn't a whole lot of pedagogical instruction going on. It's very much andragogy all the way there, but the problem is there isn't much facilitation from faculty either. There's no mercy, if you don't get something no one will help except for your peers; and, you're not allowed to re-take any final exams if you fail one. The tests themselves also seemed designed to make people fail - lots of strangely worded questions, multiple answers of equal plausibility, questions with no "good" answers, etc.
I believe you end up coming out of the program with a very deep knowledge-base, probably more than the average paramedic school. The problem is, students are very much left on their own to learn. Really though it's the not being able to re-take any finals you fail, especially the A&P final, that kills a lot of students.
