About Me

I graduated from the University of Notre Dame with a BA in Business Administration with an emphasis in Accounting in 1974, and graduated Magna Cum Laude as a member of the McAuliffe Honor Society from the University of San Francisco School of Law in 1977. 

Since 1978, I have  focused on construction and real estate law, both transactional and litigation.  I have  successfully represented owners, general contractors, subcontractors, material suppliers and design professionals in multiple aspects of construction law through negotiations, mediations, arbitrations and trials.  My successful jury verdicts and arbitration awards include recovering damages for fraud, breach of construction contract claims, defense of a multi-million dollar personal injury claim, and successful defense of liquidated damages claims in the millions.

I have handled numerous real estate transactions including office buildings, apartments and storage facilities and I have litigated numerous real estate disputes involving leases, purchase agreements and loan documents.

I have served on the Boards of AGCC (Santa Clara District), the American Subcontractors Association Bay Area Chapter (ASA), the University of Notre Dame Alumni of San Jose and Silicon Valley, St. Mary’s School of Los Gatos, the Los Gatos Chamber of Commerce  and the Los Gatos Christmas Foundation. I  live in Los Gatos with my  wife Terry.
