“Dr. Metyas is very knowledgeable and although he has so many patients, this doesn’t hinder him from giving us his full attention. He reviews the medical record, explains the case very well and takes the time to answer all our questions on each visit. He ensures that we get all what is needed. I also like that he has lab and X-Ray on site. This makes things much easier for patients to get many things done in one place and maybe in one or two visits. I highly recommend Dr. Metyas.”
“I have only good things to say about Dr. Samy Metyas. I have many Pulmonary issues and Dr.Metyas although he is a Rhuematologist stepped in and went the extra mile to care for me. My Pulmonologist wasn’t caring for me at all and this became evident to Dr.Metyas so he took the lead and started to bring me down from 40 mg of Prednisone consistently and now I am at 5mg.”
“I would like to give a big shout out to Samy Metyas Starting with the front office when you walk in they give you a warm welcome w/ smile to Bianca for fighting hard & getting my medicine approved . Dr. Samy Metyas for his experience and knowledge for treating my illness, relieving me from pain and being able to work without any restrictions. Thank you”
“Dr.Metyas has great experience and expertise!”
