Dr. Fleseriu's been great. She's been helping me get better after the brain tumor was removed, and she's still working with me to continue getting better. So, no, she's been great and I'm really glad that I have her as my doctor.

Dr. Fleseriu is very knowledgeable, very passionate, and very interested in the pituitary gland and those that suffer from tumors on it. Sometimes... I got the impression that she was pre-destined to evaluate what I may or may not have said, but... and was certainly abrupt occasionally, but for the most part she was approachable, knowledgeable, concerned and responsive. Overall, I thought the experience rated an 8.

I was very impressed with Dr. Fleseriu. She is more knowledgeable about my specific medical condition than any other doctor I have encountered. Within a short amount of time, she had educated me on several different areas of my pituitary disorders - more than I have learned over the previous 20 years. I quickly developed trust with her, seeing how well she knows pituitary conditions. She was armed with a plan of action right away, the key word being "action." There was none of the same old "we are doing all we can, there is little we know, just deal with it," etc. I think the most important thing is that Dr. Fleseriu provided me with hope, which I had lost a long time ago. I look forward to my new treatment with Dr. Fleseriu. I feel like I am finally in capable hands!
