Who We Are
Third Plateau is a social impact and philanthropy consulting firm. We partner with nonprofits, philanthropists, families, and the public sector to achieve transformative, community-centered impact.

OUR PHILOSOPHY

We work with clients and communities as partners in achieving a future where people and the planet thrive – creating meaning and joy in the process. At Third Plateau, we lead with partnership, evidence, equity, and optimism for a fundamentally better world. Everything we do, internally and externally, is rooted in our four core values:

TEAM UP

We recognize that people are at the center of social change and approach our interactions with the belief that we will go further together than we can alone. We cultivate relationships and collaborations rooted in trust and shared purpose. Centering empathy, we develop deep and authentic connections with those around us. We ask for what we need and lead with generosity to provide for others.

STEP UP

We passionately rise to the challenge of co-creating a just world we have yet to see but know is possible. We courageously and boldly advocate for the health, vibrancy, and prosperity of all and advance equity for current and future generations. We embrace our work with purpose, intention, and creativity. We experiment, take calculated risks, and question the status quo in an effort to design solutions that can scale impact swiftly and broadly.

LEARN UP

We know that communities closest to the challenge are closest to the solutions, so we stay insatiably curious and lead with humility and an open mind. We actively listen, reflect, and explore with individuals from varied backgrounds, perspectives, and lived experiences to address gaps in our understanding. We push the boundaries of our thinking by asking powerful questions and integrating diverse ways of learning. We commit to continuous learning and adaptation, celebrating progress over perfection for ourselves and those around us.

LIVE UP

We believe all people are naturally creative, resourceful, and whole. We care for ourselves, each other, and our communities by finding meaning and joy in our work, practicing balance, and prioritizing wellness. We center authentic connection to help nurture a resilient, creative, and vibrant team, which is vital for fostering fulfillment in our work. We are here to improve our communities and live fully while we do it.

Not sure you meet 100% of our qualifications? Research shows that men apply for jobs when they meet an average of 60% of the criteria. Yet, women and other people who are systematically marginalized tend to only apply if they meet every requirement. If you believe you could excel in this role, we encourage you to apply. We are dedicated to considering a broad array of candidates, including those with diverse workplace experiences and backgrounds. Whether you're new to this field, returning to work after a gap in employment, looking to transition, or taking the next step in your career, we would be glad to have you on our radar.

At Third Plateau, we believe in the power of diverse teams. In our recruiting efforts, we always seek to reach a broad and diverse pool of applicants to ensure our final candidates are not a homogeneous group in terms of demographics or experience. You can read more about our commitment to Equity & Belonging (DEI) here. We welcome applicants of all backgrounds. Third Plateau is committed to providing equal employment opportunities to all employees and applicants for employment without regard to their race, color, age, religious creed, sexual orientation, or other personal characteristics.

A compensation committee will meet to discuss potential starting salary within the band by weighing the candidate's expected contribution in terms of previous experience and expertise against current Third Plateau employees. We commit to sharing the reasoning used to determine starting salary with you. The expectation is not for new team members to be hired with a starting salary at the top of the band, but to have a salary that adequately compensates experience and expertise while countering pay inequality and upholding internal parity.
