One of the best tax services you can get in our area. My father used this company when he was…read morealive, and they helped me with his estate filings after he passed. They are professional, on time, and extremely accurate. They found an error on a K-1 that will save us $300!!! This K-1 is from a LLC and NONE of the other accountants/tax people found the error. We are so happy that we are signed up with Madelyne, it makes what could be a very stressful filing all that much easier, and we know that she is there looking after us and has the expertise one needs to protect their clients. . No one likes filing taxes, but knowing Madelyne is working on our taxes makes the entire process smooth and quick.

In the wake of losing everything in 2017 Tubbs wildfire, our tax reporting became very complex, and…read moreour CPAs at the time did not have the experience to help us navigate the tax waters without significant loss. After paying substantial amounts in the ensuing years, we were told there would be an even greater amount to pay, which we finally took as a cue to seek other tax support. After interviewing several tax professionals, we were very fortunate to find Madelyne Cromwell, principal of Cromwell Tax & Bookkeeping (CTB). Our taxes-including those we'd already paid- took a significant turn for the better. CTB has been our tax go-to tax consultants since then. A bonus has been that Madelyne has shared with us tax programs we didn't know about that further reduce our taxes as seniors. Smart, honest, expert in Fed, state and local tax law and process, Madelyne is the consummate professional who really cares about her clients, as does her staff. They have our highest recommendation.

I have seen numerous nutritionists in Sonoma County, and I think that she is the best because she offers a simple and sustainable approach to maintaining a healthy and balanced diet. I have lost 20 pounds this year, that I would attribute my weight loss to the nutrition guidelines that she has taught. Also, she helps with time management living a relaxed and balanced lifestyle juggling work and personal interests, that is essential to having a well-rounded lifestyle. I appreciate that she helped me implement a plan to set up an online piano teaching business in Sonoma County, and she had various ideas to marketing my services virtually, that will be a dramatic and exciting change instead of teaching in person like I used to in the past.

I strongly recommend that you look for someone else given her unprofessional behavior, lack of follow through, and substandard work.

After payment and uploading all the necessary documents, I received nothing -- no review, no draft amendment, no summary of findings.

On my most recent follow up by phone, text and portal messaging to ask about the status when even after two months no work had been done, he stopped responding entirely.

She stays current on tax law, is detail oriented and my returns are prepared quickly and accurately. Best of all, she's got an upbeat temperament and is an absolute joy to work with. Her office staff are friendly and welcoming, too. I've had other tax preparers scream at me because they couldn't handle the stress of tax season. I've had two different preparers make serious mistakes that would have cost me a lot of money had I not caught the errors. Not Amy. She's professional, absolutely competent, and a joy to work with. I can relax during tax season knowing that I'm in good hands.
