About Us

Based in Los Angeles, Rathbun Sargent Insurance and Financial Services helps organizations of 2 to 100 employees get the most appropriate, cost-effective benefits for their needs, no matter how complex. Founded in 2007, we service clients spanning diverse industries, such as manufacturing, apparel, medical, legal and financial services.

Whether you have a startup business or a well-established operation, we search the market for options and simplify the process so that your company isn’t unnecessarily taxed – administratively or financially.

Unlike many brokers working for larger enterprises, we are independent and focused on what’s best for you, and don’t leave you hanging as soon as your benefit plans are in place.

Our clients work directly with the firm’s principals, who have over 55 years of combined experience in insurance and financial services:
