PAS is a quality mom and pop school, it specializes in foreign students but locals are welcome. Herb is a top notch instructor although he does require a thick skin at times. I highly approve of his teaching. He has solid ideas and cockpit flows based on decades of study and practice. I have had instructors give dogmatic ideas based on very little theory and even sometimes incorrect theory, and I find it easier to study with those who base what they teach on open and enthusiastic discussion based on open sources, with lots of experience. That's what you are getting with Herb if you are open to it.
