Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Extremely knowledgeable and very helpful!

Dr. Siyam is the worst doctor I have ever seen. He diagnosed me with Hashimotos and prescribed a small dose of synthroid. Frequently he confused me with different patients and gave advice for me to take prenatal vitamins at one point because he believed I was another patient that was currently pregnant.I expressed my concerns with my health again he threw a tantrum saying that nothing was wrong with me and that no one can help me. He shook his head and said I underestimated his intelligence.

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.

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
