As founding principal and lead designer at CosciaMoos, Sergio Coscia guides the firm’s creative direction with a global perspective and sensitivity to local context. He’s passionate about understanding the historic fabric of cities from a cultural and social perspective, and committed to designing buildings that respect that sense of place. But Sergio balances his deference with boldness, guided by a belief that introducing new ideas into our cities makes them more vital and more resonant with the way we live.
Sergio was born in Belgium, raised in Italy and Philadelphia, and has worked throughout Europe, East Asia, and the Middle East. He co-founded CosciaMoos to share his international experience with large-scale projects while cultivating a deeper connection with clients and the places he works. Sergio believes the best projects are built on strong relationships, and today he leads a team of well-rounded designers that value clear communication at every stage of the process.
An active member of the Urban Land Institute, Sergio sits on the ULI Urban Revitalization Council, which explores new solutions for reinvigorating of cities, neighborhoods, and communities. He supports the local arts community and finds inspiration for his own practice as Chair of the Board of Directors for The Clay Studio, a non-profit institution dedicated to promoting and developing the ceramic arts. And he also enjoys exploring culture and history at home in the kitchen, curing meats or in the garage, restoring a 1984 his Alfa Romeo Spider, or and on the track racing vintage cars practicing the art of driving fast.
Sergio Coscia, AIA, is a registered architect in Pennsylvania, New York, New Jersey, Washington DC, and North Carolina. He is an alumnus of the University of Pennsylvania and holds a Master of Architecture degree from the University of Maryland.
Founding principal and managing partner David Moos keeps CosciaMoos thriving, clients happy, and everything running smoothly. He believes in designing solutions--not just buildings--and approaches each project with an open mind and a collaborative spirit. David works closely with clients to ensure the firm's work supports their partners' vision, their values, and their budget. Through a combination of imagination and foresight, he crafts spaces that improve lives today, while remaining flexible enough to accommodate any unexpected changes tomorrow.
A fast learner with a good business sense, David co-founded CosciaMoos to create a practice that offers clients the specialized knowledge and experience he gained working at larger firms, with the attention to detail and personal service of a smaller practice. His professionalism and expertise in the higher-ed and healthcare sectors have helped CosciaMoos grow from a scrappy startup to a resilient firm with a national presence.
David connects with a wide network of interdisciplinary professionals as an active member of the Urban Land Institute, where he co-founded the Philadelphia Health and Life Sciences Product Council. In all his pursuits, he is driven by a strong curiosity, a passion for learning new ideas, and a desire to experience new ways of seeing the world. The same drive to take risks and try new things that has helped CosciaMoos grow keeps David taking on new challenges outside the office, whether it's figuring out how to cool a wine cellar or building a timber-framed barn himself.
David Moos, AIA, is licensed to practice in 26 states. He holds a Master's Degree in Architecture from the University of Texas at Austin and a BA in History from Brown University.
