About Us

Who We Are

Since the day Granite Mountain Insurance opened our doors we have strived to build relationships with our customers based upon a foundation of honesty, integrity and professionalism. The founder David Hanlon began his insurance career as a claims adjuster. His firsthand knowledge of the vast number of uninsured and underinsured drivers on the road has played a vital role in development of our agency practices.

We are a full service insurance agency, providing coverage for auto insurance, home insurance, commercial life insurance and variety of other policies. It is important to us that we work with carriers that we know will be there for our clients at their most critical hours. Companies like Mercury Insurance, who has grown to be one of the largest auto insurance carriers in California. As well as Progressive Insurance, the number #1 writer of auto insurance among independent agents.

We promise to grow and adapt as you do, in order to make sure you are protected where ever you are in life.
