Please Touch Community Garden

An open space where art and life happen.

Who We Are & Who is Helping

The Please Touch Community Garden is based upon the idea that bringing together communities that may otherwise never meet can create amazing things.

Everyone brings their own slice of the pie- whether in expertise, knowledge, resources or energy, and together as a team, we are able to make this awesome project a reality.

Back Info:

In 2010, local artist Gk Callahan partnered with LightHouse for the Blind and Visually Impaired to obtain a grant from the San Francisco Arts Commission for an ambitious project: a large-scale community garden that would be accessible to all, regardless of disability. We named this project the Please Touch Community Garden—And here we are!!!

The Permaculture students who help us see the vision

Zaira Lopez
Zaira is a permaculture designer living in San Francisco, originally from Guadalajara, Jalisco.

She has always been in love with nature, arts, and community with a dream to help create sustainable areas where people of all kinds can use their energy in a positive way for the world.

Her main goal is continuous learning and growing, for herself and the Cosmos around her, on all levels, everywhere. 

Sean Howe
From a harbor town in Washington, Sean grew up around salt water inlets, forest and mountains.

His upbringing in this beautiful region has played a large role in his interests in art and permaculture. He attended the University of Washington and studied Ceramics. Working with clay allowed an even deeper appreciation for all the amazing materials we find here on earth.

Since moving to San Francisco Sean has been working at art museums installing the shows and collecting excess materials for his own art. He enjoys using found objects and materials because they are free and can bring a history to guide his imagination.

He took a permaculture class last winter.
