"WARNING- STAY AWAY FROM STONY BROOK ENDOCRINOLOGY- THEY JUST FIRED ME AS A PATIENT BECAUZD THEY REFUSED TO HELP ME WITH MY NEW PUMP THAT THEY HAD RECOMMENDED TO GET IT. ELIZABETH THE OFFICE MANAGER SAID SHE WILL SEND ME A LSIT OF NEW PRACTICES AND I SAID WELL DO YOU KNOW HOW LONG IT TAKES TO FIND A NEW ENDO AND SHE TOLD ME IN HER OWN WORDS “YOU’LL BE FINE”. STAY FAR FAR AWAY! DR CHANG DOES NOT CARE ABOUT HIS PATIENTS! HE TOOK 3 WEEKS TO CALL ME BACK WHEN MY BLOOD SUAGRS WERE IN THE 300s DUE TO PARTUM, LUCKILY MY AMAZING MFM DOCTOR WAS ANKE TO ADJUST MY NUMBERS UNTIL DR CHANG DECIDED TO DO HIS JOB"

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.
