I was diagnosed with Hashimoto's Thyroiditis 10 years ago and had been treated primarily by my family physician. In the fall of 2013, my meds were no longer regulating my levels and I was referred to Dr Yoo for evaluation. I had thoroughly researched my issues including blogs and support groups and was skeptical that Dr Yoo would listen to my concerns, as folks were saying most Endo doctors only treat to the labs and not the symptoms. To my surprise and delight, Dr Yoo was extremely open to my research findings and quest to try different approaches other than the regimen I had been following. In addition, her suggestion to go gluten free even though I did not test intolerant, proved to be effective in taming some of my more bothersome problems involving inflammation. Unlike other Endos I have tried, she does not push unwanted medications and is willing to work within your comfort zone. I highly recommend Dr Yoo and her office. They are efficient and have a pleasant manner.
