Always listens. Know he hears what I share. Doesn't always assure that I understand rationale for his decisions or my body's ability to, or inability to, convert one type of thyroid to another.

Overall experience was very good, only negative is that I am still waiting to hear on my test results and I was supposed to be called on Monday. I feel no news is good news but would appreciate confirmation.

Some of my other doctors do not agree with something Dr. Ansar recommended and advised me to find another doctor. I told him about this and he told me to have any provider with issues to call him directly. That made me feel better so I was not caught in the middle.

This was only the 2nd visit, but I really like how he is treating my symptoms. I was on a very strong dose of thyroid med. and he has drastically reduced my dose. He is very thorough. So far I am very confident he will get my dosage right.

I really like Dr. Ansar and find him very knowledgeable as an endocrinologist. I do wish, at times, he would be a little less rushed when meeting with me. (I'm aware that I am pretty on top of my Type 1 care and most often have very few concerns)
