Dr. Yoon is so down-to-earth, personable and caring. After my dermatologist of 20+ years retired, I wanted to find a new dermatologist which I felt as comfortable with as before. I went to two different dermatologists and a PA, the last two to treat a basal cell skin cancer. I did not feel totally confident with treatment for the basal cell until I saw Dr. Yoon. I love Dr. Yoon! Thank you.

The whole experience could only have been better if I had not had to be there at all.. aka no Basal Cell to remove. Your professionalism and confidence as well as your caring compassion care is truly remarkable. Thank you so much. Andrea Dalton Rau Washignton, MO

I so appreciate the care I received from Dr. Yoon and his staff. His kindness and excellence made me feel comfortable about having surgery. I felt as if a friend or someone who was concerned about my life was taking care of me. The surgery went perfectly. He's the best there is as far as I'm concerned!
