InlineAdam's Review Sourced from Google
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

We are proud to have been able to offer a beautiful Modernfold panel recovery job to give the walls a facelift to complete newly renovated meeting rooms at Deloitte in Rockefeller Plaza. Deloitte has always been such a great and dear client of ours! We look forward to continuing to work together in the future!

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.

Sandra Smith's Review Sourced from Google
I they do not care about their customers!I have been with them for over 40 years! I was just notified I was no longer wanted as a client.I called and text 3 people I knew there, asking why they were canceling my simple tax account.NO ANSWERES. Then a month later I got an email saying they were down sizing!Is this how you treat a loyal customer of over 40 years that does a simple tax return? I always relied on this company and the people in it. I feel so disrespected. I would never trust them again.

Peter Keast, Sr.'s Review Sourced from Google
Computer technology has vastly improved many of our lives, even in the non-profit world. The issues are cost, reliability and maintenance. It is too much for a small business owner to become an expert in these areas. I'm not even sure it is possible. Having a partner - a paid vendor, yes, but a still a partner that respects your budget, responds quickly to problems as they arrive, and proactively seeks to protect your network from crashes and malware is invaluable. We feel like we have that partner with Whittlesey Technologies. Every year we meet to discuss vendor agreements and performance. Whittlesey Technologies has never been considered for replacement. They are our partner.

We have been using Whittlesey Technology as our service provider since the mid 2000’s. They have managed multiple server & software implementations over the years with ease while giving us the communication and proactive guidance we need. They have also provided very responsive day to day support. We look at Whittlesey as a trusted partner and part of our team.

RA Review from Google

RA's Review Sourced from Google
As an accounting firm I would give them 1 star. I recently discovered a litany of deductions they failed to consider. You will be given an EA, which is just a glorified tax preparer. They will know nothing and be slow to reply. You might as well get your taxes done by H&R block or a proper independent CPA. If these folks do your taxes, get prepared for a larger tax bill. I strongly advise against it.
