We went to see Dr Kumasaka for a rare skin disease called DRESS. He pretended he knew what he was doing. He caused my husband a horrible relapse. This doctor is so prideful and did not even do his homework, like reading medical journal. When I asked if he's treated someone with this condition, he was not truthful. He even told us to stop reading and researching. He was not compassionate with bad bedside manner. If you have a serious condition, go somewhere else. I'm so glad we found a more experienced and compassionate dermatologist

Have gone to Dr Kumasaka since he was in Federal Way. The commute for me is considerably more now, but I would go to no other Dermatologist..

Dr. Kumasaka is an amazing doctor. The only draw back is because he is so good it is very difficult to get an appointment. He is booked up months in advance. If you are an existing patient they can usually get you in within a month. I highly recommend Dr. Kumasaka!
