My experience could not have been better. I had read about the procedure prior to coming into the office. But my nurse, I think it was Duane, and Dr. Yoon were both professional, efficient and entertaining. If you have to have a MOHS procedure, this is the place to do it. Thank you.

I was fortunate to be able to have my treatment completed in one pass. As crowded as the waiting room was, I think it would have been a real mental and physical challenge to sit in there for several hours. I was only there one hour and I was asking myself how I was going to be able to endure many hours.

Dr. Yoon is excellent at his profession! He does an awesome job from start to finish even in adverse conditions where the electric went out and the generator never came on! I would totally refer anyone to Dr Yoon! I couldn't say enough about the doctor himself!

Dr Yoon does amazing work. I had my 2nd MOHS procedure with him a couple of weeks ago and the site is healing beautifully on my face! The 1st scar, also on my face, is barely noticeable.
