    I have been Dr.Koo’s patient for over 36 years. I dread the day he retires. He is warm, compassionate, thorough, caring, etc. etc. everything you want in a doctor. I miss the days when he was an independent physician. Although he does all in his power to maintain that traditional physician patient relationship, being a part of a medical conglomerate like Optum, all is not in his power. That is very frustrating for both patient and doctor.
