Dr. Warren Woo initial motivation to study medicine came from three areas of interest: the challenge of advancing medical science, the complexity of human beings and their systems, and the relational aspect of caring for patients. During his childhood, Dr. Woo experienced kindness and compassion from his own family physician, and this made an impact upon him in choosing to specialize in family practice. He most enjoys hearing from a patient that “what we did for them changed their life.” He also enjoys helping to give patients more quality years to enjoy time with their family and significant events in their lives through improved healthcare. Prior to beginning medical school, Dr. Woo gained life experience as a grocery store clerk, a door-to-door salesperson selling cookware, and a math tutor, chemistry assistant and summer camp counselor while in college. Prior to starting medical school, he worked as a tennis pro.

Dr Woo has been my doctor for many, many years It's hard to explain the Patient / Doctor relationship we have had - like part of the family We had our last appt yesterday as he is retiring. It was very emotional as he is like the brother watching me to make sure I'm OK. If I were in the hospital in intensive care he would appear at the window peering in with a smile letting me know all would be well He said he would still be teaching which is a blessing to the profession I have to stop - too many Tears The world is a better place because of him He truly shows the shield of "Heart of a Lion, Hands of a Woman, and Eye of an Eagle"

Sorry to learn he is retiring soon

Dr. Woo is the best of the best. He takes time to talk to you. You never feel rushed. He offers his professional opinions and sends you for necessary outside testing and whatever. And you couldn't find a better guy. If you had to rate all the doctors that work at (word removed), I'd put him in the top two or three. Anyway, I'm sorry to hear that he's retiring and it's a real shame and a real loss for you guys.

Dr Woo is the best doctor I've had in my life. He is a careful listener and proactive to care for you after listening to your concerns. A rare gem these days when often you feel like the hospital is more a business than a health care facility. Highly highly recommend.

Thank you Dr Warren Woo for over 20 plus years of being my primary care physician. I can't imagine having to see someone else during that time period. (PHI removed)

Dr. Woo and the staff have always been very nice and helpful. We moved to Henderson, NV back in 1988 and ever since then, we have traveled to CA for our primary care. Dr. Woo is an excellent doctor!

Dr. Woo is a physician that is rarely able to be seen lately these days because he is simply the best. I've known him for 20 years and there's nobody better to give you the treatment and to look into whatever concerns you might have regarding your health. I wouldn't trade him for the world.
