Jonathan Kurtz


Principal, Lead Designer


Jonathan Kurtz is a Principal and Lead Designer at Westlake Reed Leskosky where he holds creative inquiry, observation, intuition, and calculated risk-taking as universal values. Underscoring this philosophy is the certainty that engaging clients in a creative, collaborative process -- regardless of project type -- will result in unique solutions and projects that improve the daily life of users. His work is evidence of a close interrogation of programming needs and an expansion of the 'problem' at hand to include landscapes, economics, and circumstances of a much broader context. Much of his work has been in the Cultural Arts and in academic environments where the building's performance is measured by both technical complexity and social ambition. Jonathan leads the creative process for design competitions and commissioned work, operating interchangeably at the urban design and building scale. He oversees projects from conceptual development to execution and construction.

Jonathan has been an Adjunct Professor at Kent State University, where his focus is on Undergraduate and Master's design studios. His studio research focuses on processes that establish formal organization as a primary ingredient in problem-solving and culture-making. He has been a guest critic at Harvard University's Graduate School of Design, the Knowlton School of...
