The O'Brien Builders' Team

MIKE O'BRIEN, Founder/Owner
In 1989 after 15 years serving the construction industry from laborer to commercial project management, Mr. O'Brien founded O'Brien Builders targeting niche general contractor work for projects up to $15 million. With experience and integrity in hand, he quickly realized his vision, core values and capabilities fit the needs of the Northern California market. Mr. O'Brien learned the value of a strong support group first-hand from his previous management postions at the Hoffmann Company, the Zimmerman Company and BCI General Contractors. He surrounded himself with an experienced professional staff, growing the business in the private sector with competitive bidding through a negotiated process. With his expertise in new and tenant improvement commercial construction, O'Brien Builders excels in Class A office buildings, seismic retrofit work, tilt-up construction, site civil improvements and multi-use projects. O'Brien Builders is increasingly sought out for their experience and capability in the area of health care, imaging and medical facility construction. The Company is uniquely qualified to manage complex specifications, leading edge technology and a broad range of use requirements.

Mr. Sene brings a distinguished background in accounting to O'Brien Builders. Pierre earned his Bachelor's Degree In Macroeconomics Planning from the University of Dakar in Dakar, Senegal and holds a Master's in Business Administration from San Francisco State University with an emphasis in construction management. Mr. Sene has over 10 years experience as Controller for several prestigious construction and engineering firms in the Bay Area. His activities outside of work are a reflection of his strong discipline.
