Here are some handwritten comments from people who attended a recent one-day PCT program taught by Carl.  Here are some of those comments:

      • Carl is an excellent presenter.  He made a very dry subject tolerable.  And maybe even enjoyable.
      • Mr. Oppedahl did an excellent job at keeping the audience’s attention for this all-day class.  I have been to other seminars where I keep going back for more coffee to stay awake.
      • [It would] be nice [if it could] be a two-day event so [we] can go more in depth.
