Certified Public Accountants

Team Profiles


Mark Elsberg, CPA is respected for his expert knowledge, but that's not the only reason his clients refer their friends, family and business associates to him. They also trust that Mark will look after their interests with the same care and diligence as he does his own.

With more than 40 years of experience as a practicing CPA, Mark has in-depth experience across a full spectrum of individual and business accounting and financial advisory services. By providing knowledge, guidance and a common sense perspective, Mark helps clients make difficult decisions and implement innovative solutions on both personal and management levels. He enjoys counseling individuals who have a broad range of financial needs, as well as business clients from diverse industries in all stages of the business cycle.

Mark received his Bachelor of Science degree in accounting from Cal State Northridge. He immediately joined a national CPA firm, where he gained large company experience. Within four years, Mark realized that he wanted a more hands-on approach, and he pursued the kind of close client interaction that only a small firm could offer. In 1991 he merged with an acquired firm that would become Elsberg & Garrett, LLP.

Mark is also well-regarded in his community. Civic-minded, he has been involved with a variety of local non-profit organizations. When he is not sitting behind a desk, Mark enjoys the outdoors.
