A nimble, talented team, up for any challenge

Work with Block and you'll experience a refreshing mix of construction and design veterans and enthusiastic, service-driven industry newcomers. We all share the belief that the best work comes from strong client relationships — and that happens here from the top down.

Owners Jason Keller, Steve Keller, and PJ Simpson visit project sites weekly, and Jason is personally involved in all project estimates. Our project managers also communicate directly with the firm partners, eliminating the excessive hierarchy that can affect a project's progress and ultimate success.

Jason Keller

Owner

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

PJ Simpson

Owner

PJ Simpson was hired as one of the very first Block employees to work as an estimator, and he has stayed through the growing pains as Block expanded, serving in almost all capacities within the company. From Lead Estimator, to Project Manager, to Safety Director, to Operations Manager, PJ's attention to detail, his tenacity, and client relations are unsurpassed. Currently, PJ serves as Vice President of Block Companies, LLC. While earning a Bachelor’s Degree in Construction Management from LSU, he worked in the field from the ground up – starting as a laborer and advancing to project management. PJ also served as Block’s preconstruction manager for several years. This thorough understanding of all aspects of construction has given him the perspective needed to manage even the most complex projects while maintaining tight budgets and quality control. His experience is varied ranging from multi-family, commercial, municipal, highway and bridge to industrial. Since joining Block, PJ has managed a wide range of projects including our featured Juban Crossing project which includes a shopping center, tilt-up construction, large scale site work, and tenant build-outs.

PJ has now become an owner in Block and is a big part of the company’s current success.
