Continuing under M. David Lee’s leadership, the firm is committed to distinctive design outcomes and avoiding the direct application of stored solutions, whether found in research or the firm’s past projects. S+L’s obligation to its clients is to offer innovation, creativity, and practicality, and a fresh approach that respects clients’ needs and aspirations.
