Harold William Kolb

Tucked into one of the East Bay's fastest-growing communities, Harold William Kolb consistently ranks among the top elementary schools in all of California, with math scores that are genuinely hard to beat. Dublin has transformed over the past decade into a vibrant, family-friendly city with newer housing, great parks, and easy freeway and BART access — attracting a lot of ambitious, education-focused families who want suburban comfort without straying too far from the Bay Area's job centers. If you're relocating to the Tri-Valley and strong academics are at the top of your list, Kolb is the kind of school that makes a neighborhood feel like the right choice.
