I had a wonderful visit the Dr. was very caring and he listen to all the concerns I had. He really made me feel as he understood how I was feeling and he put me to ease on some of the things I thought was wrong with me he assured me I didn't didn't have what I thought in my head I had. I go back for more testing. He's a wonderful Dr. I recommend anyone who needs an endocrinologist give this DR a call, he will take care of you.

As someone who is seeking help, I would never recommend seeing Dr. Houssein. I have never been treated so poorly. He doesn't seem to care about his patients. According to Dr. Houssein I have an enlarged thyroid, cyst on my thyroid but no concern. I have hot flashes, unexplained weight gain, and struggling with severe hormone issues and dealing with infertility. According to him I just need to get my anxiety in check and I run too much so that's why I can't get pregnant. He also doesn't want me back in his office. I WILL NEVER see this Dr. again who only cares about the money over his patients.

I was greatly disappointed that they wouldn’t do bloodwork in the office as usual therefore I had to go to the hospital and I get charged a large amount and I’ve been keeping away from having to go to the hospital bc of it.
