"My first visit and appointment was excellent.I should’ve been seeing an endocrinologist a long time ago.I finally decided to look for an endocrinologist and lo and behold and by luck (no I don’t have a rabbits foot) Dr.Grace Youngeun Kangs name appears amongst other excellent endocrinologist.I chose Dr.Grace Youngeun Kang.She has good reviews and has good resumes.I was pretty sure and confident that Dr.Grace Youngeun Kang would be good for me as my diabetic Doctor. On my first visit and medical consultation it was decided by the doctor that a change in dose on one of my medication would help me control my sugar count.After getting my blood work done at the office she received the results days later.That’s when she decided to change the dose on my medication and boy did it work! Thank You Dr. Grace Youngeun Kang. I like your medical credentials better, you ROCK DOC."

"Dr. Kang is probably the best doctor that I have ever been associated with for any type of condition. She is very professional, has a great demeanor and is extremely empathetic towards her patients. Very lucky to have Dr. Kang as my endocrinologist. And she is a veteran; having served as a doctor in the US Army."

Data Transparency and Trust: Understanding WebMD Doctor Listings and Reviews

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.

We value your input and encourage you to reach out to our support team if you encounter any issues.
