Our Team Members

Jeffrey Jahnke

AIA Studio Principal

Jeff brings over 30 years of experience in all aspects of project design, management, and construction. As a registered architect and member of the American Institute of Architects, Jeff received his five-year Bachelor of Architecture degree from the New York Institute of Technology in Old Westbury, New York. His studies focused on movable and kinetic architecture, full-scale object construction, and the application of color theory to spatial architecture.

Jeff's design philosophy is shaped by travel, outdoor experiences, and artistic passion—influences that bring unique perspectives to every project. His extensive background ensures that HAPi projects benefit from both creative vision and practical expertise.
