About me


          Until Lionel Sawyer & Collins dissolved in 2014, I was for over 20 years a tax attorney and shareholder in its Las Vegas office, specializing in Nevada business entity formations and operations - - especially tax planning, financial analysis, and negotiation of operating agreements for partnerships and limited liability companies.  I continue to practice in those areas for business clients, but now also provide personal financial planning, tax planning, investment planning and retirement planning for individuals.

          Before switching to the legal field, I was an aeronautical engineer with the US Air Force.  I worked on developing flight simulators for fighter pilot training, first at an Air Force base near my hometown in Ohio, then at a base outside of Phoenix, Arizona.  During the time in Phoenix I also attended Arizona State University, earning an MBA and Ph.D. that researched the underlying theories and value of technical trading methods for stock investments (tip: buy high, sell higher).

          I attended UCLA law school from 1986 to 1989, where I was an editor on the UCLA Law Review.  After graduation I joined the Los Angeles office of Skadden Arps as a litigation attorney.  I handled depositions and drafted motions in complex financial litigation matters, including defense of claims by a group of Japanese banks regarding massive student loan servicing defaults.  Along the way I also acquired credentials as a Certified Financial Planner and Chartered Financial Analyst.


          I joined Lionel Sawyer & Collins in 1994 as an associate after completing the LL.M. (masters in taxation) program at New York University, and became a shareholder in 2000.  My practice was grounded in taxation, financial issues, and business entity formation/selection advice.  I also act as an arbitrator for the Financial Industry Regulatory Authority (FINRA, formerly NASD) regarding broker customer claims of unsuitable investments and churning.

          I have been responsible for hundreds of LLC operating agreements, partnership agreements, S corporation formations, close corporations, C corporation transactions/reorganizations, tax-deferred (1031) property exchanges, and non-profit foundation formations.  On several occasions clients have appreciated being advised of provisions drafted by their venture partners that could, under certain scenarios, produce economic or tax results contrary to their understandings from the oral business deal.  Noticing and resolving those issues early helped avoided later disputes and expensive litigation.


         Outside the office I can be found looking for the best pizza in Las Vegas, or playing in national poker and bridge tournaments.        


          I have authored legal and financial journal articles, including "The Trader's Edge"  published in Barron's, comparing the curious taxation of investors, traders, sports professionals, gamblers and criminal activities (tip:  be a golf pro if you can; or a criminal; but never a gambler).  Most recently, an article in Nevada Lawyer, "Tips on TIPS," described the unusual taxation of inflation-protected Treasury securities.
