Humanity is not thinking less of yourself but thinking of yourself less. Combining age appropriate philosophy, logic, moral education, and community service might add up an education in being a humanitarian. Or you could send a child to Marin Horizon and watch them grock it and rock it. Let`s all rock our humanity!

The third grade was our first year, then fourth, and now fifth. When we moved to the area from the East Coast and shortly thereafter started school, we arrived to some school events a bit after they had started. Around the third time running late, I sighed to a parent, "We're the late family," to which he replied with a smile, "So, are we going to start labeling, now?" The wisdom in his warmth signaled to me that we were in a special place. Since then, I have grown used to a parent mentioning non-violent communication (also known as compassionate communication) or hearing a teacher-lecturer speak of labeling the behavior, not the child. The school seems to strike a common-sensical balance in so many realms (work/play; being little/growing up; independence/interdependence; events/breaks; strict education/social opportunities), and, in this busy world, our Marin Horizon students have taught us some practical mindfulness techniques. I get such a good sense and have a solid feeling of trust, having spent many a morning or an afternoon and having met most everyone, by now. The teachers are conversant in the whole child, even to the degree of keeping up with technology trends of Eighth Graders... and even to the degree of knowing that the whole child can be nurtured in the midst of family and community and found in broader community.Our child had been labeled (gifted- "twice exceptional") and we had labeled ourselves (privileged-"wage slaves").Yet no one had given us any concrete means of how, through school community, to use these products. Marin Horizon gave us that, also! I'd say it "upgraded" us or "evolved" us as a family and as conscious and engaged citizen-neighbors. I have to admit, I am very proud to be a Marin Horizon parent!
