Patient Comments (5)
I was sorely disappointed with my visit with Dr. Joy. She flippantly changed my medications a few times, did not seem to listen or understand my concerns, and even reduced my medication to a point where I could barely function. I called the office a few times during these few awful weeks and was never allowed to speak directly with the doctor, rather she sent messages through her secretary. I felt the doctor had more concern for making $ off me than my actual well-being.
Great bedside manner. Answers all of my questions (and I have a lot). Explains everything. Never makes me feel rushed.

I have been a patient of Dr. Joy's for 3 years. She is an outstanding physician, who diagnosed my wacky off the chard high then off the chart low thyroid test results, and talked to me until I thoroughly understood what was happening to my thyroid and how it affected the rest of my body. She found cancer nodules when they were very very small, and recommended me to an excellent surgeon. Dr. Joy's followup care has been equally excellent these past two years since thyroid removal.

Having gone through a total thyroidectomy due to thyroid cancer, I must rely on thyroid replacement meds to act as my thyroid. Dr. Joy did not give me the correct dose of my thyroid hormone meds. Without the proper dose, I became increasing weak, ill, almost ending up in the hospital. I had a very difficult time trying to convey the state of my health and rapidly decreasing thyroid hormone levels to Dr. Joy. The office personnel refused to let me speak to the dr. The patient portal was a joke.

I switched doctors because I moved. She didn't listen to my needs. I had been on 2 other medications for my hypothyroid which didn't work. And finally found one that did. Since I wasn't a doctor she pretty much didn't care of what I said. And she wanted to put me back on a medication I was already on. Said some symptoms I had weren't because of my thyroid (which after I switched again my new doctor told me they were symptoms of my thyroid being low). I had only seen her once. Won't go back!
