Ellen is such a pleasure to work with! She has been doing my wife's taxes for years; always straightforward, no problems. I do my own taxes, but this year I had to do a new form and the instructions didn't make sense. I did my best, then boiled my concerns down to a question for Ellen. She responded immediately, gave me advice that saved me tens of thousands, as a courtesy to my wife. Whatever your concerns, give her a call, you will be glad you did!

Ellen is super! I contacted Ellen for a 10-minute consultation to understand her services and she was able to answer my questions! So helpful, honest and transparent, and easy to understand (especially being someone who is very unknowledgeable about tax terms and lingo). I would highly recommend her!

First time I contacted Ellen was when my former CPA messed up my return and was not even willing to properly review and fix it. Ellen quickly found (and corrected) the mistakes and explained them to me in details. Ellen is kind of CPA you want on your team.

I've been looking for a new tax person for my family business for years and finally had the time to make the leap last year. Given my past experience with other CPAs I was very nervous, but I am so happy to have found such a professional, kind, and efficient tax preparer!! Ellen is worth every penny :) She was very professional setting up calls via zoom and over the phone. Look forward to working with her bookkeeping team as well! Please, if you are considering looking for a new tax accountant for business or personal, I 100% recommend Ellen and her team.
