L. Anthony Navarro - PE

Partner, Engineer of Record

Anthony joined LDC in 2005 and holds a PE license in six states; he has been the managing Professional Engineer since 2010. Anthony has a diverse background in MEP engineering, the permitting process and LEED Certification. His engineering philosophy follows Louis Sullivan when he wrote “form ever follows function”. While always striving to engineer the most efficient systems, Anthony understands that there is such thing as a budget and if the design is too expensive then it simply will never be built.
