Andy Der, CPA

Principal CPA

Andy is the Principal CPA at Morris & Associates, where he has guided clients through tax preparation, planning, and advisory work for over 30 years. He took over the principal role from longtime owner Mark Morris and has been the steady technical hand behind the firm's tax practice ever since.

​

Over the course of his career, Andy has built a reputation for clarity, judgment, and follow-through. His clients tend to stay with him for decades, and many have referred their families, partners, and businesses into the firm over the years. He works across individual returns, businesses, trusts, and multi-entity family groups, with deep familiarity in the kinds of complex situations Bay Area clients bring.

​

Andy continues to serve as the Principal CPA on his existing engagements and remains the primary point of contact for the relationships he has built. His role is unchanged.
