"During my 33 years with the IRS, I saw many taxpayers with ineffective representation in dealing with their tax problems. Some tried to do it themselves, which is usually too difficult, given the complexity of the tax laws. Others hired professionals who had no specific training or experience in taxation or, unfortunately, did not have the taxpayer's best interests in mind. Now I am an advocate for clients, using all my experience and knowledge to resolve their IRS problems in the best possible manner and at the least cost. I dealt with Zaino Law Group, LPA on many occasions during my career with the IRS. In all of those dealings, I found this firm to be honest, cooperative, and highly knowledgeable. I am now privileged to be a member of their team, dedicated to quality service to our taxpaying clients."
