Overview

Mission

STEM Marin Fund is organized to raise funds to help support the STEM Marin Science, Technology, Engineering and Math program at San Marin High School in Novato, California. Our chief activity is to raise funds to support the program, including speakers who have interesting technology or science-related professions. The fund will disburse funds according to the supplemental needs of teachers with funding to go toward project materials, classroom supplies, tools and instruments, technology and field trips.

What it reported doing in 2025

The STEM Marin Fund continued its mission in 2025 to expand and enhance STEM education opportunities for students through fundraising, program support, and experiential learning initiatives. During the year, the organization hosted its annual fundraising event, which brought together community members, educators, families, and local supporters to raise funds for STEM-focused educational programs. Proceeds from these efforts helped fund Engineering Capstone projects, enabling students to design, build, and present real-world engineering solutions, as well as Biotechnology end-of-year student projects that provided hands-on scientific research and collaborative learning experiences. In addition, the organization supported numerous educational field trips designed to expose students to STEM careers, universities, laboratories, and industry environments, helping deepen student engagement and inspire future academic and professional pathways in science, technology, engineering, and mathematics.

Operating model

Revenue model
Cannot be determined from the filing. The filing does not provide enough consistent revenue detail to tell how this nonprofit funds its work.
Distribution model
Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.

The verdict

SUPPORTED - The filed numbers largely add up and revenue comfortably covers expenses. A relatively small share of available resources goes toward mission work and reported officer compensation is a large share of total spending, which may reflect staffing concentration.
