Tim Martinez is an outdoor educator, conservationist, and cultural ecologist with over 15 years of experience restoring habitat, designing native gardens, leading traditional skills workshops, and building programs that reconnect people to land, ancestry, and community.

His work is rooted in a lifelong relationship with the canyons and hills of the San Gabriel Mountains and informed by his Tecuexe (Indigenous Mexican), Celtic, and Iberian ancestry. A dedicated genealogist, Tim draws personal meaning from the ancestral threads that connect land, culture, and healing.

He has advised cities like Pasadena, Glendale, and nearby unincorporated communities through commissions, advisory groups, and public planning processes focused on urban forestry, environmental planning, sustainability and biodiversity. For more than six years, he has served as a Commissioner in Pasadena, helping shape land-use policies with an emphasis on ecological integrity and cultural respect.

Through Arroyo Sage Outdoor School, Tim offers walks, workshops, and consultations that help people reconnect with nature, restore land, and remember older ways of living. Whether making fire by hand, tending oaks, or guiding a community garden project, his work is always rooted in place — and in listening to the land.
