Patrick HamiltonR. Patrick Hamilton, Chief Executive Officer

Patrick Hamilton’s personal business experience includes carpentry, tile setting and design, site work, drafting building plans, landscape design and installation, hardwood and other flooring installation, and working with Candace Killman Design of Marin. He is also a California Culinary Academy-trained chef who still understands serious cooking. Designing kitchens is one of our specialties. Patrick is also a founding member — and the first president of — the Sonoma Valley Executives Association (SVEA).

Robert S. Bradley, Chief Financial Officer

Robert Bradley started in the construction industry in 1985. He worked as the project manager for a Foster City based construction company for over ten years. In 1998 he formed his own construction company specializing in commercial tenant improvements and electrical installations. In addition to being the CFO, he is also the Responsible Managing Officer (RMO) on file with the Contractors State License Board for the Corporation and holds B and C10 license classifications.

Our crew

For 20 years our head designer was a lead carpenter. This background helps immensely in design decisions, cost effectiveness, and methods of construction.

Our job supervisor has over 25 years in the construction business, and each of our carpenters has almost as much. Our in-house electrician has been working in his trade for over 20 years.  

Our younger employees are being trained correctly and they are enthusiastic and very eager to please both client and boss.  

Each of us at Patrick Hamilton Construction, Inc is committed to doing what it takes to “design and build complete customer satisfaction.”  We have the experience to do your job the right way—and we know how to puzzle things out if problems arise.

Green Building Awareness

We attend conferences and conventions regarding Green Building and LEED (Leadership in Energy and Environmental Design). We are very mindful of designing and building with regard to the health of the environment and have always been aware of recycling building materials. Green Building is not a fad and we are striving to be among the leaders in the field.


We have several construction crews available which helps us maximize our ability to work on a wide variety of home building or remodeling projects in Marin, Napa, and Sonoma Counties. We carefully track the crews to ensure that each is on schedule, allowing us to work very efficiently on more than one construction job at once.

Reliability and Confidence

We are the builders who have nice things said about them. We do not have folks complaining about what time we start work nor about how we manage the safety and cleanliness of our job sites.

We are the builders who show up every weekday at 7:15 AM and begin work at 7:30, take a 30 minute lunch at 12:00, clean the job site at 3:45, and go home at 4:00.  Every day. You will never wonder where we are.

We are the designers who understand proportion, scale, and taste — and who use those skills to create your style — not impose ours.

We are the design/build firm whose operation is small enough to keep overhead low and therefore offer more affordable fees. We use the latest Computer Aided Drafting programs (CAD) for our projects and we can even hand draw when necessary — an almost forgotten craft.
