The Atrium is the heart of Altadena Girls — a bright, open space designed for connection, creativity, and community.

By day, it’s a place to lounge on the lush couch, work at the community table, or grab a spot at the Activation Bar to dream up your next idea. By night, it transforms — hosting pop-ups, performances, workshops, and moments that bring girls together in new ways.

Whether you’re here to hang out, collaborate, or just take a breath, the Atrium is where everything comes to life.
