Who We Are

Firm history of L.K. McLean Associates

Founded in 1950 by Louis K. McLean, a professional engineer and land surveyor, the firm originated in Wantagh, Nassau County, NY. Initially focused on surveying and mapping residential subdivisions during the post-World War II period, when returning U.S. servicemen were establishing families, the firm's core functions persist in surveying and mapping to this day. In the late 1950s, founder Lou (Mac) McLean moved the firm to Patchogue in Suffolk County, assuming the role of de-facto Town Engineer for Brookhaven Town. The firm relocated to its current location in the hamlet of Brookhaven in 1982. George Kaigh, a licensed Professional Engineer and Land Surveyor, joined the firm in its early years, and Mac retired in 1993 after over 40 years in leadership, with George following suit in 2005.

In the 1960s, the firm began working with the Suffolk County Department of Public Works, establishing an enduring partnership that persists today. LKMA served as the designer for numerous County roads, contributing to DPW's significant highway construction expansion during the 1960s and 1970s. In the 1990s, guided by Gene Daly and Ray DiBiase, the company expanded its clientele to include major entities such as the NY State Department of Transportation and the Port Authority of NY and NJ, experiencing substantial growth to reach its current size.
