Colleen Baldwin's Review Sourced from Google
Don't go to Honeck O'Toole. They overcharged us, would not tell us why when we asked. We were clients for 2 years and they dropped us without warning during tax season. It is extremely unprofessional for them to dropped us at time where it makes it impossible for us to find another accountant in time to be able to file our taxes on time. Don't use them.

We used Honeck O'Toole for over two years. The first year we had no issues, we paid $400 for our return and had a good relationship with Sue and Joyce.The second year everything was going well, until we received an invoice for 6x (2400+) the previous year's return. We had spoken to them on several occasions and were expecting a higher bill, however we were expecting maybe 500-600 more, not 2000 more!We asked for an itemized invoice since we were shocked and confused by the 600% markup. We ultimately called and paid the invoice in full and offered to prepay for the upcoming tax return since we wanted to salvage the relationship and we were late paying the previous bill since we needed to understand the charges. We were told by Kathy that she needed to check on the cost and would get back to us. We then received a letter in the mail, firing us as a client in the MIDDLE OF FEBRUARY.

Do not use this business they will fail you time and time again. They will also not provide any services to you and still try to charge you. You will also have to file an extension because they do not know how to hire more employees so that things are done on time.

So sphiscated accounting systems I must say. For what? Never saw an irs payable in any return they asked me to prepare although I’m no licensed accountant. No names no whistle just a honest google review. Makes me wonder what an accountant does, cooking books or AICPA reporting them. No mark up in my basis. The roc building is beyond comprehension though, they even do SNL up or down stairs never got to see a show so I don’t know

Deloitte completely failed implementation of Army IgnitEd, which led to thousands of service members paying out of pocket for education expenses. The circus that we watched unfold leaves me with zero confidence in the services that this firm provides.

Dr Oullette and his team (Cyndi, Mandy, Samantha, lab guys) have changed my life for the better. I used to be scared of the dentist, and while procedures may be daunting, at this office I feel completely secure, cared for, and calm. Their customer service and work ethic is impeccable, and I would never dream of a dentist office with such a nice vibe! If you are like I was, avoiding the dentist, this is your place. I urge you to take the first step and schedule an introductory conversation/review with Dr Oullette -it's a game changer.

I'm beyond grateful for Mike and his team. From the very beginning, I was treated like family. They were quick to respond to my emails, phone calls, and texts, and I couldn't have asked for more professionalism or expertise.I am considering buying a home this year and Mike was in constant contact with my lender to come up with the best strategy for me. He meticulously reviewed every detail of my taxes, and ended up switching gears and saving me thousands more than I anticipated. I am truly impressed!Working with Mike felt like collaborating with a trusted friend, and he made the entire experience, with something as dreaded as taxes, enjoyable. I felt valued and supported every step of the way.If you're looking for someone who truly has your best interest at heart and will go the extra mile to make sure you are filing in a way that is the most beneficial for you, you won't regret reaching out to Reeder CPA Group.Thank you so much for the excellent service and all the extra money!
