Our History

In the early days of the 20th century, two visionary entrepreneurs launched the seeds of what was to grow into the preeminent independent accounting firm in Southern California. The underpinnings of White Nelson Diehl Evans are based on the expertise of the two founders’ businesses, with extensive experience in numerous industries, including distribution, manufacturing, and real estate. We are immensely proud that some of our original clients are still with us today. The parallels between our company’s growth and that of our clients is clear. Our firm and our clients grew in a highly competitive market that was rich in opportunity. We all succeeded and prospered through the application of steady, hard work that benefitted the entire community.

Along the way, we never lost sight of our core principles, and our commitment is as strong today as it was at our founding. The result is a large independent practice with offices in San Diego and Orange Counties serving thousands of clients every year. We grow in size and scope to match the needs of our clients. After all, the needs of our clients were the core of our founders’ visions, and to that end, we have built an exceptional practice staffed by the finest individuals.

Now into our fourth generation of leadership, White Nelson Diehl Evans still remains loyal to our founding principles of reliable service, consistency, technical proficiency and professional diligence. The business landscape of not just the Orange and San Diego Counties, but all of Southern California, has matured and evolved in dramatic ways since the days of our founding. But you need look no further than White Nelson Diehl Evans LLP to find a firm that has remained steadfast in its principles as it has adapted to the ever changing needs of our clients, our community and our profession.
