For 100 years, our mission has remained the same: protecting families, businesses, and futures with unwavering commitment and integrity. What began as a small, family-owned insurance agency a century ago has grown into a trusted leader in the industry, built on a foundation of service and reliability.
 

TSM was originally founded by Art Powell in 1928. Nearly five decades later, in 1975, Tony Miligi joined the agency as a producer, bringing with him a deep passion for community-focused service. In 1981, Tony and his partners took a bold step by acquiring the Powell Agency and officially forming TSM Insurance. With a vision for growth and a passion for serving the Central Valley, they laid the groundwork for a company that would stand the test of time.
 

In 1986, TSM acquired Grange Insurance Company in the Central Valley, the oldest and most well-known insurance firm at the time, through a strategic purchase from Hedberg and Offerman. This landmark acquisition marked a major turning point in TSM’s history, significantly expanding its footprint and reinforcing its leadership in the region.
 

In 1990, Tony’s son, Guy Miligi, joined the agency, bringing a fresh perspective and a deep commitment to continuing the family legacy. Over the years, he played a key role in the company’s expansion and success. For the past 20 years, Guy has overseen the day-to-day operations, ensuring that TSM Insurance remains at the forefront of the industry. Today, he serves as the acting President, guiding the company with the same integrity and dedication that have defined it for a century.
 

A pivotal moment in 1991 further shaped TSM Insurance when it merged with Clark & Clark Insurance, owned by Randy Clark and his father, Lowell Clark. This strategic partnership strengthened our expertise, deepened our industry presence, and reinforced our commitment to providing comprehensive and personalized insurance solutions.
 

In 2010, we continued our expansion with the acquisition of the Oliver Simas Agency in Manteca, California, further enhancing our ability to provide tailored insurance solutions and exceptional service to clients in the region.
 

In 2021, TSM Insurance acquired Davis & Associates, a respected Stockton-based agency owned by Bob and Nelson Davis and Tom Chiarchianis. With a 60-year legacy of serving the Stockton community, Davis & Associates brought decades of experience and deep local roots to the TSM family. This further expanded our presence in the Central Valley and reinforced our commitment to trusted, community-based service.
 

Most recently, in 2023, TSM Insurance acquired Arrowhead Insurance, with locations in Modesto and Redding, California. This expansion marked a significant milestone in our growth, allowing us to serve even more individuals, families, and businesses across the region.
 

Throughout the decades, TSM Insurance has remained steadfast in its core values: integrity, reliability, and a client-first approach. Our dedication to exceptional service has allowed us to evolve, adapt, and grow while always keeping our clients at the heart of everything we do.
 

Now, as we celebrate 100 years of service, we look ahead with the same passion and commitment that started it all. Our mission remains clear. We provide personalized insurance and financial solutions that empower individuals, families, and businesses while strengthening the communities we serve.
 

From a small family agency to an industry leader, our legacy is built on trust. It is driven by service and dedicated to protecting what matters most today, tomorrow, and for generations to come.
