Dr. Ko is the best of the best. He oversees my care with goals in mind and explains a clear strategy to get there. I want to be very aggressive with my cancer and he has supported me every step of the way. He has accurately predicted my response to chemotherapy and has inspired me to have a very positive attitude by letting me know what to expect during treatment and he has reassured me about all of my concerns.
