  • Upper School Students March to Marin City

    On Thursday, February 4, over 100 upper school students, faculty, and administrators marched from Marin Horizon's main campus in Mill Valley to Rocky Graham Park in Marin City. Marin City is the most racially diverse city in all of Marin, with mostly Black and Latinx families, many of whom are a part of Marin Horizon and Horizon Community School. With the start of the Black Lives Matter at School Week of Action, February 1-5, and to kick off Black History month, we thought it was appropriate and mission-aligned to do the march. Black Lives Matter at School is a national coalition organizing for racial justice in education. Their motto is: A Week of Action. A Year of Purpose. A Lifetime of Practice.
