Our Purpose

We’re a Family Company

We create places, homes and Neighborhoods where people belong.

Every Detail Matters

We craft every detail of the experience and every inch of the design.

Nurturing The World Together

We give our time, effort and on average over 30% of our cash flow to bring positive change locally and beyond.

Our History: I Am Home

In 1965, our founder, Sanford Diller, saw an opportunity to invest in the future of Silicon Valley. Inspired by our namesake, the Greek titan who symbolized innovation and foresight, he built Prometheus Real Estate Group, a company focused on an entrepreneurial spirit.

Sanford had the vision to transform apartment living and did so with care and attention applied to every detail. From site selection and design to service and innovation, no detail was considered too small.

He also saw an opportunity to change the impersonal nature of the apartment industry. Focusing on connecting with others in a meaningful way to create a lasting impression is one of the foundational elements to our company’s culture. This sense of belonging extends beyond our Promethean employees and touches the communities in which we serve as I AM HOME is brought to life for our Neighbors every day.

This culture of excellence and success enabled Prometheus and the Helen Diller Family Foundations to give back. Sanford set the example and invested in others to carry the torch forward and continues to light our way.
Sanford spoke often about his deeply held family belief:

“There’s no one way to make your way in the world. Everyone’s path is their own. But we all have a responsibility to give back. It’s an obligation, a duty and a privilege, not a choice.”

We continue to honor that philosophy today.

Porch: Nurturing Our Neighborhoods

The Promethean Outreach and Community Help program (Porch) empowers Prometheans to give back in their communities and beyond. Nearly half of our Prometheans volunteer every year for the causes they feel passionately about.

As an organization, we have adopted non-profits in every market in which we operate. With 14+ partnerships in place, we look forward to continuing to grow and expand our efforts.

Delight In The Details

Sanford saw an opportunity in the apartment industry not just to connect to the community, but to create one as well. With a curated approach to design, sustainable initiatives, expansive landscaping and gardening, and a diverse offering of floorplans, our apartments are more than luxury apartments. They’re homes.
