MJR provides assurance, tax, accounting and advisory services to private companies, businesses, individuals, and qualified retirement plans. Because we understand you, your business and your industry, we can help you understand and manage changes to optimize your bottom line. MJR was founded in 1955 and remains a locally-owned firm with our office in Ontario, California. Over the years, MJR has become one of the preeminent firms in the Inland Empire. Focusing on counties including Riverside, San Bernardino, Los Angeles and Orange we provide tax, assurance and advisory services to private companies, real estate clients, non-profits, dealerships, manufacturers, agri-business, distributors, professional services firms, and more.

While MJR's client base resides primarily in Southern California, our reach extends across the country and around the world through our membership in the BDO Seidman Alliance. Our membership in the Alliance enables us to provide a full range of services to our clients, previously available only from the large national firms, while we maintain the personalized service of a local firm.

The BDO Seidman Alliance is a nationwide association of independently owned local and regional accounting, consulting and service firms with similar client service goals.
