Our History
The RS Crum story goes back to 1976 when our founder, Richard S. Crum, established one of the first fee-only financial advisory firms in the country, which was an innovative and bold move given the commission-fueled world of investments that was prevalent at the time. Mr. Crum was on to something special and today, over 40 years later, RS Crum’s commitment to providing objective, professional financial advice has never wavered.
Over the years we have worked hard to build an environment that is both flexible and comfortable for our clients while maintaining a high priority on the details. We have grown as a result, but have done so carefully to make sure we have the right people in place to deliver an exceptional and highly personalized wealth management experience.
Based in Newport Beach, California, R.S. Crum, Inc. is an independent Registered Investment Advisor. With nearly $400 million in assets under management, RS Crum is regulated by the Securities and Exchange Commission.

Our Values
Values are something we take very seriously. They drive how we treat our clients, how we treat our staff, and how we live our lives. The values listed below are just words unless carried out through our daily actions, but we can proudly say our firm has been built around these same core values for over 40 years and it is our intention to guard them closely into the future.
