JASON GARCILLE
President & Owner

Jason Garcille has always been drawn to the challenge of building—both structures and strong relationships. A Lake Charles native, he graduated from Barbe High School before earning his Bachelor of Science Degree in Business from Louisiana State University. His passion for creating seamless, high-quality construction solutions was gained while working for a premiere oncology consulting firm in southeast Louisiana as the Director of Operations and Business Development and more recently as the Managing Partner of Development and Construction of a premiere national real estate developer.

Jason’s expertise lies in his ability to effectively manage all phases of construction projects, as well as supervise and direct the talented team of professionals working at SITI Construction. For Jason, the most rewarding part of construction is seeing a project come to life and knowing that it delivers exactly what the client envisioned. His commitment to quality and efficiency ensures that with SITI Construction, every build is more than just a structure—it’s a lasting success for those who depend on it.

In his free time, Jason enjoys spending time with his family; wife Jennifer and their three children Jack (16), Emily (14) and Louis (11), flying planes, hunting, cooking and cheering on the Saint Louis Catholic Saints, McNeese Cowboys and LSU Tigers.

Jason serves the community as a member of the Saint Louis Catholic High School Building Committee, the Building Committee for Saint Martin De Porres Catholic Church, and the Board of Directors for the Graywood HOA.
