"Larson Design Group is an emerging national architecture, engineering, and survey firm. Our vision is to elevate our client relationships to a higher level than the competition, enrich the careers and lives of current and future staff, and enhance the communities where our staff live and work." - Keith Kuzio (President & CEO)

Our History

Larson Design Group began with an architect, engineer, and surveyor, each with a dream to create a firm that focused on solutions that could sustain and benefit the communities it served.


Ken Larson retires from PennDOT and teams up with Hunt Engineers as they merge with Ferrell Engineering & Surveying to start an office in central Pennsylvania.


Hunt Engineer's Williamsport office merges with John Hoffman Architects to create the premier architecture, engineering, and surveying firm in the region.


The office grows to over 60 staff and employees acquire ownership through a 100% stock buyout. Larson Design Group is officially born with Ken Larson as president.


LDG grows to 125 employees and designs its new headquarters’ at Water Tower Square, an old factory with a rich history. This adaptive reuse project uses an innovative GeoExchange system for highly efficient heating and cooling.


LDG established its ESOP, giving all employees the opportunity to become employee-owners.


After becoming President in 2000, Keith Kuzio becomes CEO of Larson Design Group.


The firm opens an office in Corning New York’s Gaffer District, returning to the city of our roots. LDG initiates a rebranding initiative to position the firm for growth in new markets and geographies.


LDG establishes a presence in south central Pennsylvania, leading to our Lititz office.


The Selinsgrove office opens. LDG is selected as a Top 500 Design Firm by Engineering News Record, a Top 250 Architectural Firm by Architectural News Record, and a member of the PSMJ Circle of Excellence.


The Dominion office building becomes LDG’s first LEED certified project.


To serve new markets, LDG establishes the Energy Group, CNG Focus Group, and Facilities Engineering Group. With over 260 staff, new offices are opened in Pittsburgh, PA, Apalachin, NY, and Morgantown, WV.


The firm receives the ACEC Diamond Award for a project at Promised Land State Park, and acquires Daniel C. Baker Associates, Inc., a civil/survey firm in Western Pennsylvania.
