Sean Marcel is an associate principal of Syska Hennessy Group as well as a senior electrical engineer in the San Diego office. With more than 10 years of experience, Sean is skilled at leading projects that heavily emphasize collaborative design to accomplish architects’ and owners’ vision.

Sean, who joined Syska New York in 2006, began working in the firm’s critical facilities group, specializing in financial clients.
