Presently, Zee is the Assistant Project Manager at the Kingsessing Recreation Center in Southwest Philadelphia, working closely with Rebuild in the renovation of the century-old community center and its expansive 9.2-acre site.

With a background spanning architectural design, customer service, construction, and automotive technology, Colin offers a unique perspective that enriches every project he is a part of. With a Bachelor of Science and Architecture and a focus on facilities management, Colin’s academic foundation has equipped him with a deep understanding of the built environment and the intricacies of managing projects from conception to completion.

Outside of the office, Colin’s adventurous spirit shines through with his love for rock climbing and practice as a drummer.
