Hi Kaye,

This is there address and phone number:  Endocrine Sciences Laboratory, 4301 Lost Hills Road, Calabasas Hills CA 01301, (818)880-8040

We have been using them since my son was born.  I was told that they are one of the few labs that run CAH panels.   So, we have my son's bloods drawn at our ped's office and overnight them to CA every three months. 

As for MD's in the area, sorry but I am not familiar with any.    If you haven't already check with your Endo for a recommendation.  I would be happy to ask my son's endo at our next visit if your endo can't suggest anyone.  She is well networked ~ anytime we are planning to vacation our endo always gives us a name and number of a local endo, just in case!

Hope this helps:)
