Dr. Leslie Dawravoo is absolutely amazing. Her staff is magnificent. She is, by far, the most caring and thorough doctor I have encountered. Her treatment is only surpassed by the staff at these offices who are nothing short of astonishing. They too have such a caring approach to their patients, it boggles the mind. We have become all too accustomed to a cool approach by physicians, and this offices turns that approach on its side. There are not enough words to describe how wonderful these doctors and their staff are. If you need to see a gastroenterologist, look no further. These are the best!
