Dianne Piccioni has been my CPA for many years now. She has always been extremely professional, helpful and respectful with great communication. I have found her to be prompt and through, taking the time to answer my questions and if necessary research any complicated situations I found myself in. Such as living in the United Kingdom with foreign income. I have always found Diane personable, friendly and I enjoy speaking with her. She has helped me feel more confident about how to handle my tax preparation and I find her fees to be very reasonable. Every year I feel relaxed and relieved knowing I have such a qualified, knowledgeable professional I can count on now and in the future. Thank you Diane for caring and doing such a great job on my taxes every year. read more

April 2018: Lame staff who didn't know forms and procedures Never met the woman even after many requests for explanations, not even a returned phone call after tax season had closed. Made out IRS payment form incorrectly and I got a bill 2 months later from IRS owing more money. I advise looking further. read more

I am an attorney in San Francisco who has referred numerous clients to Diane Piccioni. They have all been very happy. She is knowledgable, responsive, and good to work with. I particularly like how honest and frank she is. As for the previous reviewer (Anthony F.), I have no doubt there is another side to that story. I am sorry he had a bad experience. But it is in no way consistent with what I have experienced. If you are a business looking for a professional CPA, Diane is an excellent choice. read more

When I first began using Diane Piccioni to do my taxes about 12 years ago, I was grateful for her honesty. She had come through for me in a difficult situation so I felt lucky to have an accountant I could rely on to be in my corner. However, in the last two and a half years I have seen a change in her. She has become extremely difficult to communicate with -- unable to give me a straight answer to a simple question, unable to explain complicated tax matters in client-friendly layperson terms and impatient with me when I ask follow-up questions. When I was trying to understand the tax implications of some shares my father had left me upon his death, she was unduly harsh in her responses, showing insensitivity to the emotional implications of the decisions I was facing. The last phone conversation I had with her that should have taken no more than 20 minutes for her to clarify something she had said previously (that I had written in my notes) went on for an hour as I struggled to understand what she was saying. Finally, the conversation devolved into her yelling at me, "You don't need to know about that! You don't need to know about that! Forget about it!" I hung up without having my question answered and was shaking in aggravation for two hours after. On the last tax return she filed for me, first I discovered she had put the wrong address on it, causing me to have to go through a long process over the phone with the IRS to prove my identity before they would release my return. (Another good reason to stop using an accountant you are aggravated by is the aggravation can make you careless in double checking their work.) Then months later, I discovered that on an obscure form way at the back of my state return, she had put yet another wrong address, resulting in communications lost in the mail and causing me penalties and fees from the state. When I asked her to share financial responsibility for these fees (which would have cost her under $200 and saved her the cost of this review) she refused. In short, although I appreciated working with Diane for several years, more recently, I have found her to be increasingly difficult to communicate with, prone to making mistakes and unwilling to take responsibility when they are brought to her attention. I have always liked her as a person but I can't recommend her as an accountant. read more

Do not use this woman, she is a total B**** and mislead us from the start, and is truly unprofessional. We did not authorize her to do our taxes, we went to meet with her to see what our options were as we our a registerd domestic couple in California, she said to leave our tax information with her and she would get back to us on what the best option would be. I had advised her that I have always filed my taxes myself on line for free through the IRS directly. She ask for our phone numbers and said she would get back to us. Two weeks go by and no phone call, finally I called her office and was advised that our taxes were done and that we needed to come by to sign the forms. I was in shock, we never told her that we wanted our taxes done we ask for her advice on the best way to file, and of course we were going to pay her for the information she was supposed to give to us. She now says we owe her $600 as the taxes have been completed. I called the office three times and only spoke to her receptionist, as she was not available, finally after my fourth call she got on the phone and proceeded to scream at me and tell me that we did tell her to do our taxes and that she was sick of me calling her office. I told her again we never authorized you to do our taxes and she knew it, she yelled and said I will send you to collections and HUNG THE PHONE UP ON ME. When I told my partner what had happened he was in disbelieve as well as we both know what was said and agreed to. At this point I was so furious with her I told my partner he better deal with her because I won't be so nice next time.... WAIT it gets better and better. My partner made an appointment to talk with her, when he arrived at the appointment she wasn't even there, her receptionist said she was out to lunch, UNREALl!!!! So my partner just wanted this nightmare to end so he paid the $600. When he got home he realized they never even told him if it was going to be direct deposit into our bank accounts or mailed to us. He called the office and they were like oh yeah, how would you like it done, lol (you can't make this stuff up) so we gave them the account number for our bank. She then calls back and leaves a voicemail stating that she had our credit union account information and that she would use that account, not our bank to deposit both of our refunds. This is the clincher!!!! On April 26 one of our refunds is deposited into our BANK not the Credit Union as was promised. So we checked the credit union to see if the other refund had been deposited into that account, and it was not. So today on April 28th I go online to track the other refund through the IRS website, and WAIT, WAIT, WAIT for it.... It states that this refund was requested as a check and will be mailed to you by May. 26. YOU CAN'T MAKE THIS SHIT UP!!!!! This woman has no class and should not be operating any kind of business, her attitude is horrible and she just is a flat out LIAR AND SCAM ARTIST. STAY FAR FAR AWAY!!!!!!!!!!! read more

We've use Diane for our two companies, our personal taxes, my husband's mom and one of our son's tax needs. I appreciate that she is there quickly whenever I need her, she finds the best options and keeps up to date with changes. It has been a pleasure to work with her all of these years AND she is a small woman owned business and local! You can't beat good service and supporting local businesses. read more
