Any Public Health Nurses in the Bay Area, California?

Are there any certified Public Health nurses in the Bay Area, California who would be willing/available for a career interview or shadowing? I have a degree in biology and I'm really interested in gaining insight into public health nursing. I will be applying to an entry level graduate program in nursing with an emphasis in community development/international nursing at UCSF. I would love to meet with nurses currently in the field of public health. I would like to eventually work abroad in developing countries with this degree. Please let me know if you or anyone you know can help me.

Thanks so much!
