LLB Architects, formerly known as Lerner Ladds Bartels, is is a leader in designing timeless environments that allow people to thrive. The architectural practice is built upon the core values of care for the environment, communities and clients. Since its founding in 1936, LLB’s success has been rooted in its ability to collaborate, explore and (re-)invent using an approach that integrates people and technology.

In 1936, Samuel Lerner, a structural engineer and professor at Brown University, founded an engineering practice in Providence. His son Steven L.

Drayton Fair, AIA, ALA, LEED AP BD+C, MCPPO joined the firm as a principal in 2003, bringing with him over 20 years of public and institutional experience.

In 2011, the firm expanding relocated to the Design Exchange in Pawtucket, leading the adaptive reuse of the building as the developer, and streamlined its name to LLB Architects. In 2018, the firm expanded again with a new office in Worcester, MA.
