Sean Jean

Project Executive (CA)

With over 23 years of experience in the construction industry, Sean Jean’s comprehensive technical background, managerial skills, and proactive attitude have been highly valued and respected by clients and industry peers. His background and ability to work on highly complex engineering systems and to supervise subcontractor productivity enables him to be an effective, decisive, and schedule-conscious leader.

Sean has been instrumental on some of our most high-profile projects including the very successful Harrah’s Rincon SoCal hotels, casino, and entertainment destination. He is part of the team of professionals who launched W.E. O’Neil, southern California into the high-rise market and leads the charge for our large multifamily and senior living portfolio in the San Diego region.

You will always have curveballs thrown at you in the construction industry, as well as your fair share of stressful situations. Having a positive team environment to fall back on gives us the tools to handle any curveball thrown at us.
