WeiserMazars LLP

Used their LI office, at first we thought they were good, but the 2^nd year we had a sales tax audit. They said they handle audits, after months we realized they lacked skills providing info to the auditors and were facing a large liability.
We hired another firm and they provided the correct docs in so doing they discovered Weiser Mazars made a $ 450K error on posting sales on our tax return. It was this error that triggered the audit.
The billed us over $ 20K for audit work estimated at 7500−10K, all wasted tried to speak to the head partners to get the over billing resolved, they declined to discuss.
Stay away from this firm we dealt with Keith Goldhamer & Christopher J. Arato, both are not capable of any audit work or tax returns.
The tax returns we later found out were done by a green accountant out of school and never fully reviewed by Keith or Chris.

I hired WeiserMazars a few months ago to deal with an audit… and …I just got” fired” from this company (yes, I am a client that was fired!) in the middle of an audit– because I questioned their excessive billing (which came months after beginning service vs every 2 weeks as should happen and which was initially requested.) They have left me high and dry with my retainer in their pocket. (they have justified keeping it for very little service thus far.)
Beware.
