Our Values

Relationships – At the heart of both mentoring and the work of supporting programs is being connected. We recognize the humanity in one another first, and endeavor to connect with staff, leadership, board members, youth, volunteers, funders, subject-matter experts, and thought-leaders to build relationships across the field.

Being of Service – We are driven by the tenets of servant leadership, and our work is in service of both young people and those who support them. We are guided by the motto: “nothing about them without them.”

Inclusivity and Equity – We believe that our services and our community are for all. We strive to include and welcome a broad array of ideas, expertise, people and organizations. Ensure that young people have the agency and self-determination to shape their own futures.

Authenticity – We know that mentoring and growth does not happen without people being real with each other. Subsequently, we work to create welcoming spaces where people and organizations can show up authentically.

Evolving – Mentoring often inspires life-long learning. We as individuals and as an organization are continuously evolving to be our best selves in service of the future of mentoring in Colorado.


MENTOR Colorado is the unifying champion for expanding quality youth mentoring relationships in Colorado. Founded by the passion and vision of a number of grassroots mentoring organizations in Colorado, Mentor Colorado leads initiatives that will strengthen communities through mentoring. MENTOR Colorado has served the mentoring field by providing a public voice; developing and delivering resources to mentoring programs nationwide; and promoting quality for mentoring through evidence-based standards, innovative research and essential tools. Together, we engage with the private, public and nonprofit sectors to ensure that all youth have the support they need through mentoring relationships to succeed at home, school and, ultimately, work.
