Warren Randolph Peterson

About me

My goal is to provide professional, high quality, reasonably priced legal services in the handling of tax controversies, which include tax audits, IRS appeals and Federal Court actions.

I decided to pursue my interest in tax law after some 28 years of legal 
practice in intellectual property and general corporate law.  I earned a 
Master of Science in Taxation from California State University East Bay in 2010 to launch my career in the tax field.  

I worked for the Internal Revenue Service, including a stint as a Revenue Agent, to gain some practical inside knowledge concerning the IRS before "hanging out my shingle."

I work with carefully selected clients with the goal of insuring that they are treated fairly by the federal and state tax authorities and that they pay only the minimum taxes legally required.  I also seek to educate my clients to minimize the likelihood of their experiencing future tax controversies.

  • Christopher Daniel Leroi

    Mr. Peterson is an exemplary attorney who I would recommend to everyone and anyone. Hiring him might very well be the best decision that you have ever made. His answers on Avvo are perfect. I have practiced for 24 years as a judge, magistrate, prosecutor, and private attorney and he is one of the best I have encountered.
