Dr Loo has been my doctor ever since i moved to Arizona. 20 years now. I have trusted him with my healthcare and he's always taken care of me. I've had times when I need to come in right away and he and his staff have always gotten me in. I hear horror stories of others who are sick and can't be seen by their primary for a week because they have no appointments available. This has never happened to me in 20 years. Thank you Dr Loo for taking such good care of me. You are appreciated more than I could even tell you.
