Dr. Mazhar is an excellent doctor

Going to a gastroenterologist for the first time was a little.. embarrassing. Let's face it, talking about bowel issues isn't the most comfortable thing, but Dr. Mazhar's bed side mannerisms and overall demenour made it a much easier experience. He is attentive, asks questions and does his best to get to the root of issues. I haven't once felt brushed off or ignored while in his care. Best doctor I've seen in a very long time.
