Marcel Monnar’s journey from confronting personal educational challenges to founding One on One Learning reflects the transformative power of empathy and innovation in education. Motivated by his own experiences as a struggling learner, Marcel recognized the urgent need for personalized instruction and established One on One Learning in 2000 with a clear mission: to ensure that every student, regardless of background, could access high-quality academic support tailored to their needs.
Under his leadership, One on One Learning has grown into a nationally recognized provider serving more than 350,000 students across 20 states. The organization is validated as an ESSA Tier II evidence-based program, underscoring its proven effectiveness and credibility in driving measurable student growth.
Central to this success is Marcel’s GAINS instructional framework (Grow, Accelerate, Individualize, Nurture, Sustain), which emphasizes accountability and measurable outcomes. Districts consistently report students advancing multiple grade levels in reading and math within a single year, while achievement gaps narrow across underserved populations.
Guided by a rare blend of entrepreneurial foresight and human-centered leadership, Marcel continues to position One on One Learning at the forefront of educational innovation. His vision not only transforms student outcomes but also empowers educators, families, and communities to reimagine what true educational equity looks like.
