Knowledgeable, personable, professional physician

My initial consultation with Dr Yoon was beyond expectation. He is an excellent listener, helped me understand what my condition could be and what the process will be to find out. I felt heard and seen. He was vey kind to me and explained everything thoroughly. One of the best visits I have ever been to, considering how sick I felt.

Excellent doctor

He was thorough and explain the complications of thyroid disease. He ordered some tests to better understand why I'm not feeling up to par. He also helped in understanding changes I could do to help myself. Thyroid disease is a tough disease to live with.

Thank you, Dr. Yoon!
