If you send me a PM with your email address, I will send you my list of non-vax friendly peds. The very best/most holistic of them, btw, aren't in the Tri-Valley but farther afield in Marin or the South Bay.
As far as naturopaths, Tara Ballew is a member of my group (holistic moms) and I hear is excellent - and she has a friendly personality http://www.dayspringclinic.com/
She's in Pleasanton.
BTW, our group has a playgroup in Mountain House and a slew of other events in the Tri-Valley - so in case you're looking for like-minded folks, check us out
