LAN was founded in 1965 by John A. Lacz, Professional Engineer & Professional Planner. LAN began in Hawthorne, New Jersey with a handful of individuals and John Lacz’s vision to create the most dynamic architectural, engineering, surveying and environmental firm possible. Since that time, LAN has grown to become one of the largest full-service architectural, surveying, engineering and environmental firms in the region, with a staff of over 75 employees.

LAN’s main corporate office occupies approximately 15,000 square feet at 445 Godwin Avenue, Midland Park, NJ. LAN also has a branch office in Goshen, New York; and a satellite office in Trumbull, Connecticut.

LAN’s unique full-service, mid-size firm ensures that we are large enough to handle any project, yet small enough to provide personal attention to our client’s needs. With close to fifty years of professional experience, we have exceptional knowledge in a wide variety of services.
