My child was under Dr. Escallon's supervision when he directed a clinic at Mt. Sinai. Although I had repeatedly requested a cognitive evaluation because my child's teachers saw problems with his expressive language, Dr. Escallon informed me, in writing, that my child did not need any testing and that the only problem was the child's relationship with his mother. (I suppose that is because I had dared to question his refusal to even have the most basic testing.) Instead, Dr. Escallon recommended talk therapy with a child who turned out to have a language processing problem. Yet he had never laid eyes on the child, much less talked to him, or examined him. His lack of care was diastrous for our family and was only overcome when I went for testing at my own expense. My child continues to suffer from this failure to diagnose and I continue to be appalled by Dr. Escallon's arrogance.
