A strong history serving California
With offices throughout California–including San Francisco, San Jose, Los Angeles, Irvine and San Diego–RSM has an expansive presence in the state that continues to be one of the major international hubs of innovation and business leadership. We serve more than 2,000 businesses in all major industries–many with a global presence. Our client base continues to grow as does our commitment to professional development of our skilled workforce. We take pride in our diversity–both within our employee base and the clients that we serve.
Commitment to the community
Our commitment to California extends beyond serving the needs of our clients. Our personnel devote their time, money and efforts to many local charitable organizations, fundraisers and events. For example, in 2015 RSM raised approximately $70,000 to benefit a variety of charities in California through the firm’s Birdies Fore Love program as a part of the 2015 RSM Classic.
