Sep 26, 2018
This has been by far the best doctor I’ve ever had I went up north for a month and when I came back he wasn’t anywhere to be found I asked the office in Apopka where was the doctor and they simply told me they didn’t know I’ve searched all over the media etc and no luck does anyone know any information on his whereabouts Dr Mendoza took the time to listen not just jump into giving me any meds or make it short on my appointments with him I didn’t have much choice but to go to a different Dr!
