Dr. Leder's bio

This content was provided by Dr. Leder "Got involved with Diabetes and Endocrinology when I was in the Navy as a young physician. I was asked to care for a type 1 diabetic who was pregnant and having multiple episodes of ketoacidosis. I gave her insulin prior to each meal as well as basal insulin. She had a good baby and the four stripper placed me in the Endo Clinic at the Philadelphia Naval Hospital. This was back in 1961 and am still doing it. I am a Fellow of both the American College of Physicians and the College of Endocrinology . I belong to the American Diabetes Association, Endocrine Society, American Association of ClinicalEndocrinologists and am certified in bone densitometry. I also maintained certification in Internal medicine by taking the Endocrine Modules in 2013 and 2014 I enjoy work and try to help sort out and treat the many different problems facing patients with complex Endocrine problems"

Patient Comments (1)
Flushing, NY |
Doctor Leder is a fairly good doctor. But his assistant nurse named Susan is NASTY!!!! She is extremely unprofessional. Just because you are having a bad day DON'T take it out on your patients!! Yelling at patients only makes things worse does not resolve anything! Dr. Leder just lost a patient. I will no longer go there nor will I recommend him all because of HER! Lucky for her I was the bigger person and did not bother yelling back. She's not worth it.
