Robert Lewin Ltd. is the best! More than 40 years ago, and ever since I started my information technology consulting business, Robert Lewin's accounting and tax preparation services have done an exceptional job for me and my family. For my company "Net Advantage Corporation" (formed in 1994), rebranded as "First Chair Technologies", and finally "Adivi Corporation" (which I sold in 2008), Robert's team has done all the tax preparation and filing work. During all these years my personal taxes have also become complicated by the formation of various limited liability (LLC) companies which, over time, have acquired, developed, and sold real estate investment projects. My personal marital status has evolved over time also, thus requiring tax filing status changes. All of this has been handled with ease by Robert and his staff. Robert Lewin Ltd. is very thorough, always helpful by suggesting ways to protect our hard earned money, and always up-to-date on the latest tax filing and legal requirements. Robert is a professional you can surely count on for prompt reliable service!
