About Orange Tree Tax & Bookkeeping

Orange Tree Tax & Bookkeeping is located in Redlands, CA and is led by Dennis Grimes, E.A., A.T.A. With more than 40 years of experience, Dennis has been involved in the financial growth of many local families, businesses and non-profit organizations. We are here to listen, collaborate and advise you on the financial decisions you make.

We have grown and matured since we began serving the Redlands community in 1988 as Aggressive Tax Service. After more than 20 years, we felt that our name no longer reflected the diversity of our firm. After much discussion, we settled on a new name of our firm, Orange Tree Tax & Bookkeeping.

Thank you for your continued support in the life of our firm.

Our Team

Dennis Grimes, E.A., A.T.A.

Dennis started the firm in 1988 after 14 years experience in public and private accounting. He attained the designation of Enrolled Agent from the Internal Revenue Service in 1990 in order to represent taxpayers before the I.R.S. in audit and collection matters. His experience in public accounting with various C.P.A. firms and working for a non-profit organization prior to starting the firm greatly benefits our current clients. Dennis’ many years of experience in tax preparation, audits, and tax planning is a great asset to our firm. You can contact Dennis by calling our office or by email.
