Thomas R. Lamons

I started my professional career in 1983 as a judicial law clerk for the Hon. Clarence Brimmer, U.S. District Judge in Wyoming. Since 1985, have worked in a variety of positions involving tax practice, including working in Washington, D.C., as  an appellate attorney working  for the United States Department of Justice, Tax Division in the Department's Honors program, working for the Department of Treasury, Office of District Counsel in Laguna Niguel, California, where I worked as a trial attorney and as an international tax attorney, working as a Special Trial Attorney in the Department of Treasury Regional Counsel Office located in Dallas, Texas, where I managed and tried "large" cases, often involving Fortune 500 companies.

In my 15 years of government practice, I represented the United States in tax litigation in numerous cases in the United States Tax Court, the United States Bankruptcy Court, and the United States Circuit Courts of Appeal.

Since 1998, I have been representing and advising clients in private practice in Southern California. I formed the Law Offices of Thomas R. Lamons, APC, in 2001.
