From providing expert guidance during audits to managing standard tax preparation, her proactive communication ensures we are never left in the dark. Thanks to her, our family business navigated through an audit smoothly, with no problems! What really sets Dana apart, though, is her demeanor. She is friendly and patient, bringing a sense of calm to high-stress financial situations that would otherwise feel overwhelming. If you want a brilliant, trustworthy CPA who treats your family business as a true partnership, I cannot recommend her highly enough!

I let him know what I was looking for and what my taxes would entail. We set up a meeting in person, although not necessary, but I felt it was better for me to do so. Vince was super knowledgeable and clarified a lot of information I was told in the past, but was not 100% true. He got my taxes done in a timely manner and it was a super straightforward process. I'll be coming back to Vince for my future tax needs!

Thank you, Yenny! Wishing you well the rest of the year and look forward to talking to you in early Feb 2026!

My father has been a client of Michelle for 3 years now. We first approached her due to a few…read morecomplicated years for his tax filings. I had spoken to several CPAs in a 20 mile radius, and we were generally turned away due to the complicated nature. We also had a horrible experience with another accounting firm prior that took the case and did a sloppy job. I was rather disheartened until I found Michelle. She and her staff are extremely professional, warm, and courteous, and it has been a pleasure working with her team. The only thing that clients should be aware of is that you may not know how much the fees will be until the documents are ready; I guess because prices are due to the amount of work/complication. It would be nice to have a ballpark cost prior to the work, but we trust Michelle and her team, so accepted this condition readily. I would say that the cost is fair for the quality of their work.

This is my second time filing my tax with Ms. Margie. She is incredibly patient, knowledgeable, and…read moregenuinely passionate about helping her clients.

She truly cares about her clients and goes above and beyond to make sure everything is handled accurately and thoroughly. If you're looking for an accountant who is trustworthy, caring, and truly dedicated to helping you, I highly recommend Ms. Margie. I'll definitely be coming back again next year!

Most unprofessional CPA ever. His assistant asked me to contact the office to speak to Tom the CPA…read moredirectly to file taxes. So I called the office and spoke to Tom, and he literally said he was very busy and did not have time for me, and simply yelled at the phone at me. This was within the first minute of the call. Maybe he was having a bad day? Very uncalled for and unprofessional, considering how my family and I gave them business for so many years. His assistants are OK, they get their jobs done but also with huge attitudes. I gave up and moved on to a much better CPA after this incident. No one deserves this kind of treatment. Tom used to be so kind and friendly. Would give ZERO star if possible.
