Executive Director/Founder – Elliott

Elliott’s upbringing… Each of us has a beginning, one that will define our purpose in life. In the case of Elliott, his purpose started way before he was born, with his father’s early life. 

Elliott’s father — who died when Elliott was five — grew up as a Latino man (his genes being 50% indigenous and 50% Spanish) in a racially and culturally diverse community Southern Colorado. In the 1940s, Elliott’s father did cross-racial, cross-cultural leadership work, especially with youth. Elliott only found out about his father’s work later in his life, after he had already invested himself deeply in the same line of work.

Whenever Elliott feels lost, he looks back at his father’s story to remember why he is here.

What is Elliott’s mission? Like his father, Elliott’s mission is to provide supportive opportunities for people to move through the shame, grief, fear, and anger to what they love, what lights them up in solidarity across our differences.

What is Elliott’s background? Elliott’s work began on the Navajo reservation, where he taught special education. Afterward, he directed a school district transition program serving students with disabilities. Later in life, he worked as a school principal both at a predominantly Latino elementary school and at a progressive, experiential middle school. Still later, Elliott taught social justice classes at Naropa University and directed the Human Rights Office for the City of Fort Collins.

What is the Story Behind The Sum? In 2006, Elliott founded The Sum ( Ever since, Elliott has worked with business, healthcare, k12 and higher education, HR, government, law enforcement, and faith communities. 

Elliott’s innovative approach, called the Power of Difference Model (PDM), focuses  on developing internal awareness of 3 primary unconscious patterns and how these play out in our lives. The model centers on learning to integrate or “leverage” the assets of  these patterns related to our differences of race, gender, religion, disability, sexual orientation, socio-economic class, and culture.

The Sum and Charlottesville…After James Fields drove his car into a crowd in Charlottesville, VA, killing Heather Heyer and injuring 40 others, Elliott moved to Charlottesville in a camper. He partnered with the Heather Heyer Foundation to create a youth program called Heyer Voices (, and he has established a faith community called The Welcome Circle ( Elliott developed a survey and support program for individuals interested in leaving hate groups and those convicted of hate crimes. He created “Solidarity Protocols” and “Solidarity Circles” — both tools for communicating across power differences. 

Furthermore, in collaboration with Dr. Carla Sherrell, Elliott designed the Power of Difference Assessment ( He is currently developing the Power of Difference Video Project, and is pioneering the online Power of Difference Certification (

Rather than some work of this nature that uses shame and blame to address issues of race, gender, etc., Elliott and his team’s approach honors perceptions of both self and others. Before we can dismantle unjust systems and institutions, we must understand ourselves. This work does that.

-Susan Sherman, Executive Director, Shenandoah National Park Trust, Charlottesville, Virginia

  What are your answers for some of the most critical questions of our time:


“What can I do about issues of race and racism?” 

“How can I live in solidarity across our differences?”

“How do I cultivate a workplace, community, or school that is safe for, and honoring of, everyone?”

“How can I ‘Be the change I want to see in the world?’” 

Often, we go after change in the world instead of the most important work which is INSIDE each of us! This is where change in the world must begin.

Supporting this internal, challenging, and ultimately joyful journey, is why The Sum exists.

We do this in three main ways:
