Mission and programs · 2023

Mission

Founded in 2006 by Peter Mayfield, a successful leader, pioneer, and innovator in mountain sports programs, Gateway Mountain Center is a 501(c)(3) nonprofit corporation operating under a Special Use Permit from Tahoe National Forest. Gateway Mountain Center brings together the transformative power of human connection and nature immersion to help young people learn, heal, and thrive. Our innovative, science-informed method called 4Roots for Growing a Human supports the emotional, mental, physical, and social well-being of all young people regardless of where they come from, their life experiences, and their physical abilities. Our work happens in all the places where young people need this support. That includes working with schools, collaborating with community groups and youth organizations, offering services at our community wellness center, and delivering our clinically supervised, nature-based, therapeutic mentoring program.

Activities or mission (Part I)

All the significant activities focus on making a positive impact on youth via nature-based programs. The 3 most significant activities include: 1. Sierra Experience, which includes both camps and school program services; 2. WHMB - Whole Hearts, Minds and Bodies focuses on nature-based therapeutic mentoring, which strives to develop awareness and confidence in young adults; 3. Wellness is a feeder program to the WHMB program, working with schools to connect with at-risk young adults dealing with a variety of life-related challenges.

  • Sierra Experience - Sierra Experience includes both camps and schools program services. Schools is more academic based. We foster a sense of wonder, connection, and inquiry. We connect youth with themselves, nature, and community with spirited and transformative adventures. Serving 4th - 12th grade students, our holistic curriculum is shaped by common core, next generation science standards, STEM principles, and best practices in current wellness, ecology, and mountain sports. Using the science of awe and systems thinking, students connect the dots between the personal and the universal.

    Expenses $845,379

  • WHMB - Whole Hearts, Minds, and Bodies is a program for young people who want to approach their lives and well-being in a full and integrated way. We utilize an approach we call Nature Based therapeutic Mentoring, which combines modern therapeutic approaches with traditional mentoring to create relationships that are deliberate and nurturing. With nature as our backdrop we guide youth through multi hour activity based sessions where they learn skills and develop the capacities they need to face their challenges and meet life with confidence

    Expenses $464,452

  • Wellness - Wellness is a feeder program to whole hearts - it's our first point of contact with building relationships with all the youth we serve. We go into schools, and we do cool things. We work closely with the principles, teachers, counselors, and psychologists. We may do up to 5 sessions like a WHMB mentor situation, but call it wellness. It turns into whole hearts when it becomes long term. We are the crisis go-to's: immigration problems, medical support, interfacing with a parent, they call us.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Grants received

The 10 largest by cash amount. The API serves every itemized grant.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 11 November 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
