What you can expect from us

Our agents have almost 70 years of collective experience and each of our agents values relationships with clients more than almost anything.  Our agents work with clients to understand the clients' needs.  Once needs are understood, our agents identify coverages that meet these needs and create the right policies.  We monitor policies once they’re in place and we keep clients informed.  We also manage risk and this helps reduce the chances that clients will need to use their insurance.  If insurance is used and claims are filed, we manage the claims.  We're also reachable whenever clients need to get a hold of us.  These are just a few of the things we do to make being our client beneficial.

I live in Santa Cruz and work in Half Moon Bay. I decided to go with Weller O'Brien in HMB because it's a smaller town, and I figured they would give me more attention and better service than if I went to someone in Santa Cruz. I wasn't let down. They are always quick to return my calls. I am more then just a policy to them. I've never had an insurance salesman go over a policy like that before. It made me confident that I was with the right group.

Kevin and all of his staff have been great in handling all of my insurance needs for my personal and business operations. Not only is it helpful having them local so I can pop in any time but they also help me understand the different insurance options available to me. Thanks Kevin

Weller O'Brien Insurance Services in Half Moon Bay, California is wonderful! On my Homeowners Insurance Policy they were able to give me better coverage and save me money. Kevin, Barbara and Adam are always courteous and friendly. If you are in their office or speaking with them on the phone they always make you feel special. I do not hesitate to refer my friends to them..

Kevin is the best! We have our business insurance with him and we are very happy. His staff is top notch and very helpful. They have a cool new office in downtown HMB, perfect for people that want a face to face in this day in age where so many things are online and impersonal. Thanks for everything Kevin and crew.....we love you.

When looking for homeowners insurance, I checked out several companies. Weller O'Brien by far had the best customer service. Their insurance coverage was comparable to other companies, only much less expensive. Every time I've called I've spoken with Betty, Adam or Kevin directly and all my questions have been answered. They even looked over my auto insurance to make sure that I was fully covered. I would highly recommend them to anyone needing new insurance or wanting to have their current insurance evaluated.
