Yelp Reviews

“Tom Theisen is the best!  Tom’s tax expertise saved us money and he educated my husband and me on many sound business principles at the same time.  We got great tax advice and strategies from Tom, our new accountant.  He and his staff made us feel comfortable throughout the entire tax preparation process.  Tom is competent, knowledgeable, professional, organized, thorough in his analysis and creative in his approach.  He and his staff worked diligently to provide us with the best service and best return.  We appreciate the time he put into answering our list of questions by email and phone.

Tom is the end-all consummate professional.  He not only knows and keeps current with all tax related information (from California to Hawaii), he educates one in a language one can understand.

We highly recommend him!” – Lois B.

“Tom Theisen has been doing my accounting and taxes since 1990. The accounting part is keeping the books and preparing annual statements for the beneficiaries of family trusts that I am responsible for as the successor trustee. His many years of experience are valuable to me when I am looking for a practical approach to a vexing task. When he doesn’t know something, he digs in, does the required homework, and always supports my needs in a timely manner.

Tom is the consummate professional that I have the upmost confidence in. Several of my family members now use Tom and they all are similarly pleased with his services.” – Bob Kelly, retired, The Boeing Company Executive

“Tom Theisen has been doing my taxes for 10 years. He is fast, efficient and helps me plan my tax strategies for each coming year. Tom’s years of experience with the intricacies of the IRS tax code and his passion (yes, passion) for accounting make him one of the best accountants you could ever find. Plus, if you like fishing and Cornhusker football, Tom’s definitely your man.” – John Henny, Sing Ink CEO and Founder of John Henny Music Academy

“Tom Theisen has been providing me with tax advice for over 40 years. Most of my dealings with Tom can be done over the telephone or the internet, but when I need to meet with him I don’t mind driving from La Canada Flintridge to Whittier.

Anyone can put the numbers into a computer and generate a tax return. However, it takes an experienced professional tax accountant (CPA) who knows the tax law and is able to provide excellent tax planning that will lower the taxes you will ultimately pay when you file your returns with the state and Federal govenments. If this is what you are looking for then Tom is your man.” – Harvey Marsh, retired, Lear Siegler CFO
