I was born in Rhode Island and moved to Thousand Oaks when I was 9. I grew up here in the Conejo Valley and went to Thousand Oaks High school where I graduated from Thousand Oaks High in 1994. Go Thousand Oaks Lancers!!!!

My Insurance office is located in Thousand Oaks right across from The Oaks Mall next to Lazy Dog and the Cheesecake Factory Restaurants. I can also proudly say that my insurance office supports our Neighboring High School. GO Newbury Park Panthers!!!! I also support my surrounding communities of Westlake, Thousand Oaks, Newbury Park, and Moorpark by being a proud member of the Westlake Village Rotary Club. One of my privileges as a Westlake Village Rotarian is that my family and I get to deliver Meals on wheels and put on community events to all our surrounding communities. We are also members of the Conejo Valley Chamber of Commerce where my amazing wife Jeanette and I are ambassadors for the Chamber, supporting local businesses and welcoming new businesses to our community.

I am happily married to my incredible wife Jeanette who happens to be my office manager. We have a wonderful daughter who is in middle school in Thousand Oaks.

I am an Account Manager in Jason Giambi’ s Agency. I have been in the State Farm family for 35 years and proud to be here servicing Newbury Park, Thousand Oaks and all surrounding areas. I keep all of our policyholder’s account information up to date and as accurate as possible. You may receive a call, get an email or even a text from me when State Farm needs additional information from you on your Auto Insurance, Home Insurance, And Life Insurance. This enables us to make sure your insurance is working for you and that we haven’t missed anything that might be important. I enjoy helping customers protect what they’ve worked so hard for, through liability insurance. I also try to make the claims process as seamless as possible when an accident happens, to help our customers recover. Most of all enjoy coming into work every day and interacting with my amazing co-workers and helping our policyholders with their insurance and financial service’s needs. In my free time I enjoy exploring the Conejo Valley area and spending time with my senior kitty Eustace.
