 Verified  He was kind and thorough and allowed me ask many questions without making me feeling at all rushed. He showed me the type of needle that would be used for my young son's potential allergy shots after I asked about how the pain would be -- he wanted to assure me that it would be less than a "normal" shot or vaccine.
