If I could give this company minus stars I would.
Stay away, as all Brad Filmanowicz wants to do is take your money. Accountants are suppose to help you, not hurt you!
In our case Brad did not help us...... our taxes were done incorrectly and we had already put in for three extensions due to this firms inability to get it right the first time!! When we asked for an explanation of his services and the crazy expensive fees to date, Brad got loud and rude as he scolded us on not understanding what he did. He then demanded full payment before he would correct our taxes. He also had the nerve to threaten to report us to the Government for some made up illegal transaction he said we did. With all the time he wasted with his nonsense explanations we had to seek help elsewhere. So, not only did we have to pay for these services again but we also had to pay to correct all the errors he and his firm made to our computer records.
Even though we were granted the extensions to "file" our taxes late, us along with the other shareholders of our company were still hit with heavy penalties for "paying" late.
Stay away!!!
