Interplan LLC Celebrates 50th Anniversary

LEMONT, IL — Architecture and engineering firm Interplan LLC announces a major milestone: celebrating its 50th anniversary. Launched in 1972 in a little red school house in Lemont, Illinois, Interplan now prepares the next generation of young leaders to keep the brand vibrant and relevant while building upon the values established by the original visionary leaders.

With an emphasis on culture and workplace joy, the firm enters its 50th year with several other milestones. It just completed a company rebrand and relocation into a new 28,000-square-foot corporate headquarters office in Orlando, Florida.

Originally founded by Ray Chocholek and Lou Narcisi in 1972, Interplan began in an old vacant school house outside of Chicago. The firm quickly expanded with the opening of its Orlando office in 1982, headed up by architect Harvey Jacoby. To better serve its clients, Jacoby brought MEP engineering and permitting services in-house for the first time in 1987. The experience was further enhanced with the Civil Engineering Department being established soon after in 1993.

Today, Patrick Ringlever manages the entire company alongside a leadership team of architects and engineers. New initiatives to coach, mentor, and educate team members at all levels of the company help elevate their culture and level of service. Interplan aims to continue developing its vision over the next 50 years with more empathy, self-awareness, and innovative ideas to create space that celebrates humanity.
