About Me
Mabel Yau, MD, is the Interim Division Chief and Assistant Professor in the Division of Pediatric Endocrinology in the Jack and Lucy Clark Department of Pediatrics at the Icahn School of Medicine at Mount Sinai.
Dr. Yau received a B.A. in both Biology and Economics from New York University, graduating magna cum laude and then received her medical degree from Robert Wood Johnson Medical School in New Jersey. She completed her residency in Pediatrics and fellowship in Pediatric Endocrinology at New York Presbyterian Hospital/ Weill Cornell Medical Center.
Dr. Yau’s clinical research focused on rare genetic endocrine disorders such as congenital adrenal hyperplasia and apparent mineralocorticoid excess. She has evaluated the quality of life in children with congenital adrenal hyperplasia, studied the genetics of congenital adrenal hyperplasia to provide prenatal counseling and studied the long range outcomes of rare adrenal disorders. Dr. Yau also partners with a neurologist to see patients with Adrenoleukodystrophy in a combined clinic at which patients can see both providers in the same day.

Patient Experience Star Ratings and Comments
The Patient Experience Star Rating reflects our patients’ perception of how well their Mount Sinai provider communicated with them during an office visit. The Star Rating is based on patient responses to three questions on a patient experience survey, a standardized questionnaire sent to verified patients and distributed by a third party vendor, Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score.

Dr Yau worked in the importance of math into our visit. She also used my child's concern about being tall enough to ride a ride this summer to explain why it may be important to her to be just a little taller as an adult.
Good
Dr. Yao exceeded my expectations. She was beyond thorough and I feel very confident working working with her in the future
