What KG+D Architects does
KG+D Architects is a privately held professional services architecture and design firm headquartered in Mount Kisco, New York. The firm traces its lineage to 1934 (as Ed Fleagle, Architect) and operates today under the name KG+D, having reorganized through successive partnership names including Kaeyer, Parker & Garment and Kaeyer, Garment & Davidson. The firm is led by a group of principals including Vice President Erik Kaeyer (Design Principal, Cornell-trained), Walter Hauser, Sarah Dirsa, Brian Mangan, and Travis Schnell, following Russell Davidson's transition to Principal Emeritus in 2024 after 38 years and his prior service as 92nd President of the American Institute of Architects in 2016.
The firm delivers integrated architecture services across the full project lifecycle, including planning (master planning, building condition surveys, conceptual design studies), architecture (programming, design development, BIM-based documentation, code evaluation, consultant coordination), construction administration, interior design, and sustainable design. Its core technology stack consists of Building Information Modelling platforms — primarily Autodesk Revit, AutoCAD, and Enscape — used to coordinate design teams, produce construction documents, and support visualization. Project categories span K-12 education (the firm's primary vertical, including new construction, renovations, additions, and campus master planning for public and private districts), higher education (Yale University, SUNY Purchase), municipal and government facilities (Westchester County, Town of Bedford), recreational/club facilities (Wolf Conservation Center, Brooklawn Country Club), corporate and commercial work (IBM Corporation), healthcare and nonprofit projects (Guiding Eyes for the Blind), residential, and religious facilities. Major awards include 30+ design recognitions such as the 2022 AIA New York State Firm of the Year (the chapter's highest honor) and the AIA Excelsior Award of Distinction in Public Architecture.
KG+D operates a project-based professional-services revenue model, with fees scoped per engagement and typically billed across multi-year contract durations. Go-to-market is relationship-led and direct: principals and senior staff cultivate school district boards, municipal procurement offices, university facility planners, and private institutional clients, with project wins often dependent on public referendum approvals or competitive selection processes. Geographic focus is the Northeast United States — New York metropolitan area and the Hudson Valley — with notable client concentration in Westchester, Dutchess, Orange, and Putnam counties. Direct competitor set includes other mid-sized regional education-specialist architecture practices; the firm's differentiation rests on deep K-12 domain expertise, multi-generational client relationships, an awards-rich portfolio, and a credentialed leadership bench, rather than on technology or scale advantages.

- DLR Group: Integrated architecture and engineering firm with a heavy concentration in K-12 and higher education design. Comparable to KG+D on integrated design delivery and education specialization, with broader regional coverage.
- Perkins&Will: Global architecture practice with one of the strongest K-12 and higher-education portfolios in North America. Closely comparable to KG+D on education focus, design quality awards, and integrated interiors practice, though operating at significantly greater scale.
- Wiley|Wilson: Mid-sized architecture and engineering firm with a strong education and public-sector practice in the Mid-Atlantic and Southeast. Comparable to KG+D on firm size, vertical mix, and education-focused project delivery.
- Magnusson Architecture and Planning: Mid-sized New York-area architecture and planning firm with strong K-12 and municipal practice. Highly comparable to KG+D on size, regional base, public-sector education work, and integrated planning-to-construction-administration delivery model.
- CannonDesign: National architecture and engineering firm with a deep K-12 and higher education practice. Comparable to KG+D in education specialization, BIM-led delivery, and integrated planning-to-interiors services, but at materially larger scale and geographic breadth.
Broad incumbents
