Doctor Siyam has done a wonderful job helping me feel good again. Before seeing him my levels were always off. And I hadn't felt well in a couple years. I'm glad I found him. He treats me and not my just my TSH number. Thanks Doc.

He is a wonderful doctor and a wonderful human being. I wish I could see him for all my other needs as well. He is very thorough and has a great personality.

By far the best doctor I have seen in more than 10 years! Very thorough, good bedside manner & extremely knowledgeable in his field. I would greatly recommend him to any person with issues in Endocrinology.

Dr. Siyam at first, seemed ambitious and focused on my health issues. He diagnosed me w/ diabetes & gave me new meds by having his secretary leave a message on my phone. the next 2 visits I had with him, he focused only on my diabetes and ignored my other issues, My last visit I had with him, he got upset and acted like a teenager shrugging his shoulders and telling me to "get over it", when I voiced my opinion & didn't just agree to do what he wanted, plus threaten to keep me against my will

Dr. Siyam is a bright, intelligent, energetic physician who was one of the best young doctors at the University, went into private practice with another very promising physician. My referral to him has already paid off. He was willing to research and figure out a very difficult medical problem, something that all other Endocrinologist would not. He is also very practical and never quits trying to find the best solution. I highly recommend him.

I've never had a doctor make me feel more helpless. He diagnosed me with hypothyroid and prescribed synthroid. A month later (not feeling any better) I went back and got my blood work done assuming my levels were unchanged. To my surprise, my results showed that my TSH was normal and I was "healthy" while I still have all the hypothyroid symptoms. Dr. Siyam proceeded to not give me a plan to alleviate my other symptoms. Total lack of compassion. Categorized me as "healthy" and sent me on my way
