I live in the Philly area and 2 of my 3 children have SWCAH.  They see a pediatric endocrinologist.  I love him and I bet if you called his office and spoke with him or Jean, his nurse, they would be able to recommend a good adult endo in the area.  Dr. Iraj Rezvani, Temple Children’s Medical Center, 215-707-6430.  Good luck.
