Dr. Koo and her staff are amazing. Dr. Koo is very knowledgable and very caring. She is not one of those doctors that pushes products on you that you do not need, but she is very open and honest about what you do need. She offers samples of most prescriptions so that you can try before you buy. For me this is a must. My skin is so sensitive and often I cannot use prescriptions after purchasing. She has saved me tons of money buy offering samples first. I cannot say enough good things about her.
Have used him for years, and he's always been superb.
