DR Hsiao has treated me for squamous cell cancer of my leg, just a pimple that wouldn't heal. He knew immediately what it was and excised it. Unfortunately I went on an extensive walking vacation (not a great idea) and the wound opened again. I had a recurrence and had to have surgery again, I was worried about recurrence and actually got a second opinion, totally unnecessary as it turned out. The other dermatologist said Dr Hsaio had done everything he would have done, exactly. DR Hsaio is gentle natured and gives advice in a non judgmental manner. (I smoke) but let me know it would impact wound healing. (It did )He is one of the best doctors I have met, very thorough, kind and caring.
