About Larson & Gaston, LLP

Experienced. Efficient. Effective.

Larson & Gaston, LLP, an AV Preeminent* rated firm, was founded in 1998 by John B. Larson as Larson & Associates. Mr. Larson previously had been a partner for 11 years in an AV Preeminent* rated Los Angeles law firm. In 1999, Daniel K. Gaston merged his practice into Larson & Associates, resulting in the creation of the firm now known as Larson & Gaston, LLP.

Because our lawyers have extensive experience and belong to more than one practice group, we have developed a uniquely practical approach to legal matters. For example, our litigators understand business and that a lawsuit is often just one factor in a client’s broader strategic setting. Our transactional attorneys understand that signing a contract is important, but is only the beginning of the business relationship.

By combining legal expertise with practical experience, our attorneys provide solutions that support our clients’ long-term objectives. This professionalism and preparation has forged long-lasting relationships with many of the firm’s clients.

With an office centrally located in Pasadena, California, the firm handles matters throughout Southern California in both federal and state courts, as well as arbitration, mediation and administrative hearings.

Hired Attorney John Larson

Several years ago, we hired John Larson to help us with a problem involving a dishonest contractor. John had the experience and knew the right people to bring onboard as needed, and he was able to get the matter put to rest.
