".An excellent class overall which I will recommend to others"..."I really appreciated your explanations of some common concepts that were previously explained to me in 'foggier' ways"....."I enjoyed the class. Thank you!"......"I learned a lot. This course was very informative and a great refresher." -- students in our October 2001 AES course

The list of agencies and organizations sending students to our classes has become quite long. Below is just a sampling of some of them. Several agencies have had us back multiple times, a testimony to the value they have gotten from our work.

References -- names of past students and class organizers -- are available upon request.
