Conco’s New Southern California Region General Manager


Maizer Ouijdan

For The Conco Companies, “Topping Out” the Wilshire Grand was just the tip of the iceberg. We are proud of our part in constructing the iconic tower that has already transformed the Los Angeles skyline and will play an important role in revitalizing the downtown area. Together with our clients and trade partners, we have not only broken world records but continuously challenged our team to come up with new, innovative solutions, and we look forward to bringing that same work ethic and high standards to future projects.

As a part of our on-going commitment and focus to the Southern California construction market, Maizer Ouijdani has accepted the position of General Manager of our Southern California operations. Rick Parker,former general manager, will now bring his years of experience and extensive knowledge of the industry to focus on field operations in Southern California.

With ten years of experience as a Conco Project Manager, Maizer has a strong background in both structural engineering and construction management. He is intimately familiar with the company’s operations up and down the West Coast and has an exceptional track record and strong work ethic.  In concert with the mission and values of The Conco Companies, Maizer is eager to take the lead and is determined to continue the practice of exceeding our clients’ expectations.

Conco is honored to have earned the trust of our trade partners and clients, and we look forward to building the skylines and neighborhoods of Southern California one project after another. Contact us to learn more about our extensive concrete services.
