Diehl Evans & Co., LLP

At Diehl, Evans & Company, LLP, our commitment to serving you is built upon over 75 years of knowledge and expertise in business practices, economic trends and the ever-changing tax scene. Diehl, Evans & Company, LLP is one of the oldest CPA firms in Southern California. Ellis Diehl began his practice in Santa Ana in the 1920s. After several changes, in 1954 the firm’s name became Diehl, Evans and Company. We grew in large part due to the rapid development of Orange County. And because of its many real estate developer clients, the firm became known as one of the experts in real estate taxation and accounting in the County. We have since expanded to also provide auditing and consulting services to clients in almost every industry. We also have developed a strong base of clients among governmental agencies, in both the auditing and consulting arenas.
