Client Testimonials





“Donna has been my tax consultant and tax preparer for the last 10 years, however, I have known her for over 20 years.  She is a well respected professional who always goes out of her way to ensure all your business or personal tax needs are met properly and with maximum results”

B. Berg

Donna May came into our lives at just the right time! She was able to repair a bunch of the issues we found in our bookkeeping caused by another bookkeeper. She is personable and enjoys getting things know you and your business and not treating you like another income that is run of the mill. She treats you like a human being and not just another account. Our previous bookkeeper treated us like a plague and didn’t even try to get to know us and what we to to better understand how they could help us the best. You can’t go wrong with Donna May!

Polly Webb
