Firm History

        National Tax Consultants and its sister firm, Financial Services of Long Island, were established twenty-five years ago by Dr. William Stevenson, EA and Richard Grebinger, CPA.
        The firms offer their clients a full range of accounting, and tax and financial services that encompasses a broad spectrum of expertise. Rich handles all of the corporate clients and Bill specializes in client representation before all branches of the IRS and New York State. Both Rich and Bill prepare individual tax returns and assist clients with tax planning, purchase of businesses, and a variety of other related services. Investment services are also available as we have a full-time staff member working solely in the financial services area.
        Bill is an Enrolled Agent, a Certified Financial Planner, and earned a Doctorate in Education from Temple University in administration. In addition, he is one of about 250 professionals since 1943 who has been admitted to practice before the United States Tax Court as a nonattorney. He serves on both the IRS 'Area' and New York State Taxation and Finance Commissioner's liaison committees. He is the only Enrolled Agent to serve on the NYS Tax Tribunal's Advisory Committee. Bill has served a two-year term on the IRS Commissioner's Advisory Group and meets periodically with IRS and Congressional officials in Washington to recommend changes in procedure. In 2002 Bill was named "Accountant of the Year" by the National Society of Accountants and in July, 2006, he was appointed as "Ambassador to the IRS" for the National Society of Tax Professionals. In 1998 Bill persuaded Congress to include the change of the IRS' mission from enforcement to service in RRA '98.
        Rich is a CPA and a recognized leader in his community. He is the treasurer for David McDonough, our local New York State Assemblyman. Rich handles all corporations from the smallest to mid sized multi-state multimillion dollar firms. A few of the types of firms Rich works with include doctors, lawyers, real estate management, retail operations, manufacturing, construction management, supermarkets, international and national shipping and so forth. Rich is also the AICPA's legislative representative for the Long Island area.
        Bill, Rich and all the staff at National Tax Consultants pride themselves in having built a firm based on providing personal one-on-one service.
