Martinez area preschool/day care with organic food?

Hi!

I'm looking for a preschool/day care  for my 3 year old that is health conscious and serves organic food. I'm open to various philosophies but feel very strongly about clean, non-toxic food. Any suggestions for the Martinez area? Anything in Briones? Small home-based preschools are an additional plus!

thank you for your time, it is greatly appreciated.
