    Jason Keller

    Managing Partner

    Jason Keller is a construction industry veteran who has personal experience in every facet of multi-family and commercial construction. Over the past 29 years, he has built a reputation of outstanding customer service and an unwavering commitment to deliver projects far beyond his clients’ expectations.

    After successfully growing Block Construction in three short years, Jason partnered with his brother, Stephen, to form Block Builders, to bring a new level of dedication to the apartment, senior residence and affordable housing sectors.

    Whether it’s affordable housing to give Katrina evacuees a new home or an intimate retail space for a young entrepreneur establishing his first store, Jason believes that each customer deserves respect. He works to foster a solid relationship with his clients as well as the solid building of their dreams. This was Jason’s dream. Achieving that took hard work, close observation and a steady stream of jobs across the southeast U.S.

    Jason began working in construction during a summer “vacation” when he was only 15 years old. He was hooked. After earning his Bachelor of Science degree in construction management, he quickly became a full-time estimator for a construction firm, overseeing apartments, retail, office buildings, schools, rehabilitation, public works plants, prisons, hospitals, airport terminals, historical projects, demolition, warehouses, and athletic field projects, ranging in size from $50,000 to $100 million. With that experience under his belt, he moved to the role of project manager for a large, national construction company where he bid and managed projects. He spent the next ten years serving as an estimator, superintendent, project manager, safety director and vice president for a large Baton Rouge, LA, firm. Today he runs Block Companies LLC, where his clients benefit from his experience, his tenacity, and his desire to get the job right every time.

    Jason is a member of the Our Lady of the Lake College Advisory Committee, Rotary Club of Baton Rouge, Sigma Lambda Chi alum, Sigma Chi alum, Louisiana State University Laboratory School Foundation, and the Catholic High School Men's Club. He is also Past-President of Woodstone Home Owners' Association and formerly served on Woodstone's Architectural Review Committee. Jason currently sits on the Major Corporation Partner Committee for the National Association of Minority Contractors (NAMC)- Houston Chapter.

    Jason holds a degree in construction management from the University of Louisiana at Monroe, a nationally recognized building construction program.
