I ADORE Dr. Piacantine at Mesa Pediatrics. I don't really care for any of the other doctors there but, he's great. He's never questioned me about vaxing. He really seems to appreciate the fact that I don't come in expecting antibiotics prescrptions and is great with taking the wait and see, conservative approach.
The only thing I'm not crazy about is that he does talk about parenting - like at our last visit, he talked to me in front of the kids about setting up a reward system for behavior. We don't use or need a reward system - he just sort of tossed that out there. He's done this before with other parenting issues but, not in an overbearing way - more in a parenting helpful hints way. So, you can take that advice or leave it.
But, other than the parenting advice, I really like him and find him very easy to work with.
