Our Mission

Founded in 1951, our mission is to deliver peace of mind to our clients through the use of customized insurance solutions, and a superior level of customer service built upon a foundation of experience, trust, integrity, and professionalism.

It’s a mission that has helped us grow from our humble, treasured beginnings in agriculture to premium writings that are more than $500 million and continue to rise as our company grows.

With over 160 insurance professionals and 11 offices strategically located throughout California, Oklahoma, Texas, and North Carolina, we are considered a generalist in the types of business we write. That is clear in the wide variety of niche industries we successfully service year after year: agriculture, transportation, aviation, technology, oil & gas, construction, furniture manufacturing, RV dealers, equine mortality, waste management, home healthcare, and many more.

At Andreini & Company, we take the time to understand our clients’ needs and business objectives to offer a customized approach tailored to fit each client. This vision continues to steer us. We work hard to preserve the company’s historic dedication and commitment to delivering innovative insurance solutions and providing a superior level of customer service.
