    Dr. Sepp is the best child's doctor I have ever seen. He is caring, sensitive to needs, and very respectful even asking permission every time to the child as he does each procedure.

    I as a parent am frustrated and semi offended by the way Dr Sepp has acted about the vaccine schedule. I expressed concern and desire to follow a delayed version so my baby is getting less vaccines at one time. rather that outrightly tell me why he felt it was important to come back in a month for the delayed vaccine he told me at the scheduled 15month check up that we were being seen for a 14month check up the day after he turned 15 months old and says we needed to bring him back at 16 months for his 15 month check up. clearly this is confusing and frankly [...] if Dr. Sepp had said something like, "let's plan to be here again in a month and you can think about that vaccine some more." and given me information about it, I would have felt like he trusted my judgment as a mother and like I've been given the opportunity to make decisions for my child myself. Dr Sepp was not honest or upfront about what we were doing and it's made me feel less secure with him as my child's doctor. I don't feel I was treated like an adult or like he believed I was doing something good for my child. i likewise don't feel like he was thinking of our individual needs and I'm not sure he's doing what is best for the children he is seeing if he's responding to all similar issues in this way. I felt he was dishonest and unprofessional in how he handled the situation and communicated with me, my husband and our son.
