Patient Ratings & Comments


Comments are gathered from our patient satisfaction surveys.

Amazing Dr and team
Dr Quiros is an amazing, kind and compassionate doctor. My daughter loves him and we are so grateful for the care he gave her (and support her gave us as family). She was very sick when we first saw him and she is fully returned to health now
Everything was explained very clear to me and my father who doesn't understand much english, so we were aware of what was happening, and the workers treated us very kindly.
It was a good experience because I was able to understand my doctor really good.
