Dr. Liu is the best!!! This was my second Mohs surgery and I was totally confident with his knowledge, professionalism, and care for me as his patient. Mercy needs to make sure it gives every effort in keeping Dr. Liu in Mason City. His staff was very caring in making me feel comfortable before, during, and after my surgery. Taylor was my nurse and she was wonderful!!!

He sensed I was stressed about non-dermatology related issues, sat down and talked with me about my life. OF COURSE, it is related to my dermatology issues, he knew. Autoimmune issues. Great doctor!
