For a first visit, Dr Pak was extremely patient with me and understood my need to explain my concerns first and didn't discount them. She took the time to explain medical background and her suggested plan to help me In a calming & easy to understand way. I don't think there are enough words to describe how relieved and happy I was to have seen her. Someone who will finally help me get to the bottom of what my situation is. She is a gem.
