George C. Knowlton III

Visionary Entrepreneur · Licensed General Contractor · Community Builder

George Knowlton III didn't start with a blueprint — he started with purpose. At ten years old, he was coaching the youngest bowling league in his town. At twelve, he was up before dawn delivering 300 newspapers every morning. These early experiences didn't just build discipline — they built character, and the belief that every person deserves to be coached, supported, and given the tools to thrive.

That belief has driven every chapter of George's extraordinary journey — from managing delis in Scottsdale and training franchisees at El Pollo Asado, to co-founding CanTrim Interiors in 1992 and building safety-critical handrail systems for Centex Homes. In 1989, he broke ground on a construction career in Sacramento that continues to this day.

In 2003, George earned his licensed General Contractor credentials while simultaneously completing an AS in Natural Science and an AA in Liberal Arts from Sierra College — because for George, learning has never stopped. That same year, he organized after-school enrichment programs for local parks, and in 2005 he incorporated a nonprofit delivering football and cheer programs to youth across diverse neighborhoods.

In 2010, he added ISSA certification as an adult and youth fitness trainer to his growing list of credentials — another tool in service of helping people live stronger, healthier lives.

In 2016, George founded SMILE Company LLC — a holistic human-experience firm built around the five principles that guide everything he does: Safety, Morality, Inclusivity, Linguistic Clarity, and Experiential Value. Four years later, he launched Square Up Construction Inc., a design-build general contracting firm dedicated to ethical development and construction excellence in the Sacramento region.

In 2024, George co-founded TIDE 360, an AI-driven platform empowering businesses with interactive virtual boardrooms and real-time operational insights. That same year, he established Jane's Shared Housing Foundation — a 501(c)(3) nonprofit providing safe, supportive housing and life-skills training for autistic teens and adults.

Today George serves as Founder and CEO of Square Up Construction, while wearing the hats of Advisor, Trainer, Asset Manager, Real Estate Inspector, and Licensed General Contractor — leading light commercial, multifamily, and residential projects throughout the Sacramento region and Placer County. His philosophy is simple yet profound: lead with purpose, embrace innovation, and never forget to SMILE.

A Life Built with Purpose

From youth bowling coach to visionary entrepreneur — every chapter has been guided by the same principle: show up, build something real, and bring others with you.

Safety

Inclusivity

Great construction serves everyone. George actively builds teams, spaces, and organizations that welcome people of all backgrounds.

Linguistic Clarity

No jargon, no confusion, no fine print surprises. Clear communication is how trust is built — from the first estimate to the final walkthrough.
