For over ten years Petrucelli, Piotrowski & Co, Inc has been the office I've used to prepare my Federal and NJ State taxes. Living in North Jersey I could easily find a nearby tax preparer, yet I'd prefer making the one-hour drive to work with Tim. My experience working with Tim has been wonderful. He, as are all the employees of the office, incredibly pleasant to work with and thorough. If you want to work with an efficient and pleasant tax preparing office, well, look no further. Petrucelli, Piotrowski & Co, Inc is the office to go to. It's worth the drive. (This is not a paid announcement. 😄) Seriously, you won't be sorry to at least give the office a call.

My husband Dennis and I have had our taxes prepared by Tim Piotrowski over 20 years. Originally, when we lived in NJ and now in NC for 15 years.
Obviously, we feel he does a great job with our taxes. He returns our calls promptly, answers all our questions and prepares the taxes in a timely manner. I would recommend Tim and his team to anyone seeking a tax preparer.

Mr Joseph Petrucelli has handled all of my personal and professional financial matters for the past 11 years. From audits, taxes to financial reports for legal matters. His work is detail-oriented and his reports professional and clear. He is always available to speak to and nothing is ever to much or too difficult for him or his staff. Mr Timothy Piotrowski too is just exceptional in his approach. All of the team members are polite, kind, compassionate and hardworking. It has been such a pleasure to work with Mr Petrucelli and his amazing team. I highly recommend him for any financial matter.

P, P & Co, Inc. are great. I've been with them ever since my former accountant in Saddle River, NJ was remanded to a federal penitentiary.
Both P, P & Co. partners were and have been wonderful.
More specifically and recently, my appointment this tax season was with Tim Piotrowski on 4/6. He was, and is always, helpful, exacting, informative, kind, and considerate. I could go on and on.

I have worked with Joe Petrucelli now for the past 6 months and I can not say more about how solid an individual Joe is. I believe he is very astute when it comes to accounting and legal issues and how to optimize his client's results. I would highly recommend Joe and his Company!

Dean Koocher

I truly believe there's no short cuts when it comes to choosing the right accounting firm if you like to keep your peace of mind. I was fortunate to meet Dylan Stone right around when I opened my business. He came highly recommended among our peers and I'm so glad I took their advice. His knowledge and professionalism is unparalleled. In other words: It's the representation my family needs; I'm a client for life! LOL
