I think is all about the character of each person I love punctuality and professionalism I think DR Khalid has those qualities, also I ask aloooot of questions I want to know why, how when and exactly what is wrong with my kid in order to prevent and understand the illness better, I like to know what is the Dr giving me as treatment etc. I guess you can tell I am very picky. I do agree that he is not the friendliest Dr. But I like his work. I saw may pediatritians that were frindly, but when i start asking quiestions they didn't like it , felt I didn't trust them or worst coudn't undesstand what i was saying ..
