Board of Directors

Andrew grew up in South Africa, moved to Walnut Creek at age six, and now calls San Jose home. He holds a degree in Cognitive Science from UC San Diego and has built his career in digital design. His love of bikes started with a Schwinn High Sierra bought with birthday money at thirteen. What draws him to Good Karma Bikes is the layered impact: expanding access to opportunity, building community, and keeping usable bikes out of the waste stream. Outside of work, he bakes sourdough and pies, helps two high schoolers prepare for college, and enjoys getting his hands in the mud — making ceramics or riding trails.

Mario is a construction executive with over 30 years of leadership in laboratory and healthcare facility construction, having served as COO of XL Construction and VP of Operations at Rudolph & Sletten. He now leads Mario Wijtman Construction Advisors, a strategic consulting practice in Portola Valley. A Cal Poly San Luis Obispo graduate and member of its Architecture Dean's Leadership Council, Mario is known for his mentorship, client-centered approach, and ability to guide complex organizations through growth — expertise he brings directly to his work with Good Karma Bikes.

Dennis brings more than 40 years of financial management experience across the technology sector. A longtime San Jose resident, he has served his downtown neighborhood through volunteer work and board service, and his personal passions include bike restoration, hiking, and cycling. Dennis joins Good Karma Bikes to lend his financial acumen to an organization whose transportation mission resonates both personally and practically.

Chelsea is a nonprofit leader with over a decade of experience across homelessness services, public health, and community development. She has managed shelter operations, designed programs, and secured grants expanding services for vulnerable populations. She holds a Master of Public Health, is bilingual, and brings international perspective from her Peace Corps service. Her expertise in health equity, financial sustainability, and community engagement — combined with strategic thinking and adaptability — makes her a powerful advocate for the communities Good Karma Bikes exists to serve.

Taurean holds a graduate degree in Mechanical Engineering from Stony Brook University and serves as a Senior Product Manager at NVIDIA. A systems thinker who bridges technical complexity with human need, he excels at building innovative, high-impact teams. He also mentors underrepresented community members globally in innovation and AI. Based in San Jose, Taurean brings to Good Karma Bikes a rare combination of engineering rigor, product strategy, and deep commitment to equity.

Mike holds a Mathematics degree from Wake Forest University and spent over 22 years as a software engineer at Intel. More than two decades of volunteer work at Sacred Heart Community Service gave him a clarifying insight: for many people, the most pressing unmet need isn't food or clothing — it's transportation. That discovery drew him to Good Karma Bikes, where he now applies his analytical mindset and community-service values to one of the most overlooked drivers of opportunity and wellness.

Jim founded Good Karma Bikes to provide reliable transportation to people experiencing homelessness and low-wage workers, growing it into a program that builds self-esteem and teaches job skills in bike repair, eCommerce, and retail. His guiding principle — give away for free half of all that we make — remains at the heart of the organization. A PhD physicist, NASA intern, Wharton graduate, and certified bike mechanic, Jim is proof that the right mission can bring a whole life into focus.
