Our Team

Commitment to Diversity and Equity

Treehouse values diversity and it is expressed in all aspects of our work, from the individuals and communities we serve to our organizational culture, employees and volunteers.

We understand that historic structural inequities have influenced each one of us, and we use this knowledge to deliberately cultivate the success of all people and treat everyone with dignity, humanity and respect.

Treehouse believes that our capacity to affect sustainable change is strengthened when diverse individuals, beliefs and perspectives are included. We model an institutional commitment to equity by investing resources at all levels and working toward measurable indicators of change.
