SOREN MCADAM LLP is a regional firm of CPAs and business advisors performing a wide range of services in an exceptional manner. This is how value is created for our clients.

Brief Look at Our History

Soren McAdam LLP can be traced back to two different firms. Soren Ahern and Christenson was founded in 1979 in San Bernardino, California, and Ziilch, McAdam and Copeland dates back to 1950 in Redlands, California. The two firms merged in 1989 and have been providing exceptional client service to clients in the Inland Empire and beyond ever since.

Our Firm Today

Soren McAdam LLP has one office located in Redlands, California. We have seven partners and near fifty total people serving start-ups to hundred-million-dollar companies. Although we primarily serve clients in the Inland Empire, we continue to serve many clients located throughout the western United States.

We are an independent member of the BDO Alliance USA, a nationwide association of independently owned local and regional accounting, consulting and service firms with similar client service goals. The BDO Alliance USA presents an opportunity for firms to expand services to clients without jeopardizing our existing relationships or our autonomy by accessing the resources of BDO USA, LLP and other Alliance members. The BDO Alliance USA was developed to provide Member firms with an alternative strategy for gaining competitive advantage in the face of a changing business landscape. The Alliance represents an opportunity for BDO to enhance relationships with reputable firms that share a mutual business understanding. The BDO Alliance USA is a subsidiary of BDO USA, LLP, a Delaware limited liability partnership.

Our People

We have always had and will continue to have great people. We recruit college graduates from all of the colleges and universities in the Inland Empire, and we have always prided ourselves in our ability to attract the best students. We try to grow our talented staff from entry-level professional staff members to partners in the firm. To keep up-to-date technically, we provide more than fifty hours of continuing professional education annually to each member of our professional staff. The topics of these classes include accounting and auditing, all areas of taxation, business management issues, interpersonal skills, fraud and professional ethics. Typically, the classes are specific to one of the industries in which we specialize, or one of the services we provide. Remaining current is critical if we are to provide you with the quality of service you deserve.

As a result of the talent of the people we hire, the continuing education we provide to them and the quality of the clients they work with, our staff is prepared to provide exceptional client service. Also, by emphasizing only a few industries, our staff members quickly become well-acquainted with the unique aspects of the accounting, auditing, tax, systems and management issues in those industries.

Our City

Redlands is a city of nearly 70,000 people located within an hour’s drive from Pacific Ocean beaches and mountain resorts. From this location in the heart of Southern California’s Inland Empire, Soren McAdam serves a primary business region with more than 4 million people.

Incorporated in 1888, Redlands is one of the oldest communities in Southern California. Throughout the 1950s, it was home to the largest navel orange producing region in the world. In its early days, Redlands became a popular wintering spot for wealthy Easterners and a convenient stopover for Hollywood celebrities going from Los Angeles (50 miles west) to desert resorts in Palm Springs (50 miles east).

Today, Redlands has thrived by balancing its historic roots with modern-day amenities. Victorian and Craftsman architecture is widely visible throughout the community and the San Bernardino County Museum is right next to our offices. The University of Redlands was recently named to Forbes’ list of America’s Top Colleges, and the Redlands Bowl remains home to the nation’s oldest free summer music festival. For history buffs, the Lincoln Memorial Shrine and Historical Glass Museum offer glimpses into significant periods of America’s past.  And, in a nod to its agricultural roots, Redlands hosts “Market Night” every Thursday evening, complete with a farmer’s market, product vendors and musical entertainment.  

As a proud Redlands business, Soren McAdam is an active participant in many civic and service-based organizations. We love our town and encourage you to share in the experience.
