Joshua Kiehl serves as Principal and Technical Director at John Milner Architects, bringing extensive experience across the architecture and construction fields. A valued member of the firm from 2002 to 2008, he rejoined in 2018 and was named Principal in 2025 in recognition of his leadership, technical expertise, and meaningful contributions to both the firm and the profession. Joshua’s diverse portfolio encompasses master planning, adaptive reuse, and the renovation of existing structures, as well as the design of new buildings for cultural, ecclesiastical, and residential clients. His proficiency in project management, construction detailing, building codes, and condition assessments allows him to effectively bridge design intent with the practical demands of project execution. As Technical Director, he oversees the firm’s quality control processes, production standards, and best practices for design and contract documentation. A registered architect in multiple Mid-Atlantic states with NCARB certification, Joshua holds a Bachelor of Architecture from Drexel University. His academic distinctions include the Michael Pierson Prize Silver Medal for his thesis and the AIA Henry Adams Certificate for Excellence in the Study of Architecture. From 2011 to 2013, he volunteered with the Weyerhaeuser Company to design housing in Chambrun, Haiti, in response to the 2010 Port-au-Prince earthquake. This pro bono work supported recovery efforts in one of the region’s hardest-hit communities. He was honored with the AIA Central Pennsylvania Young Architects Award in 2014 and the Entech Engineering Unrivaled Service Award in 2015. Joshua presented at the Pennsylvania Housing Research Center RBDC Conference and the PSATS Educational Conference, sharing his insights on architecture and the built environment. His volunteer leadership includes service on the Planning and Preservation Committee of the Elfreth’s Alley Association, the Board of Directors of AIA Central Pennsylvania, and the Philadelphia Chapter of the Institute of Classical Architecture & Art (ICAA). He has also contributed to long-range planning and building committees for Veritas Academy and Wheatland Presbyterian Church in Lancaster, Pennsylvania. Outside the office, Joshua enjoys reading, upland bird hunting, and traveling with his wife and three children.
