Dr. Hanauer - Board Certified?

Does anyone know if Dr. Hanauer is board certified? In the Physician Directory from my insurance company she is not listed as one.

I would like to change doctors and I've read so many good things about Dr. Hanauer, but I would prefer a Board Certified doctor.

I'm looking for a new doctor in the Garden City area who is affiliated with Winthrop or N Shore Manhasset.

Thanks!
