I think Dennis Kort must have changed his name or used a different name for acting. I checked Facebook just for the heck of it and found a Dennis Kortsha....you never know. I found David Doramus on Facebook in the past.
I don't believe he was hiding at all. He just goes by his family name these days, which is Kortheuer. On social media, you may find Dennis on facebook. You can see photos of him as a child and also more recent.
He attended the High School of Performing Arts, in NY and studied at California State Univ - Long Beach as well as University of CA - Irvine. On another website a fellow alum of High School mentioned that he knew Dennis who was 2 years ahead of him at that school. Coincidentally, that website references information back to this very thread. So the web research has come full circle.
