Lead Attorney: Isai Bismark Cortez, Esq.

Isai, a Los Angeles native, is the lead attorney for Bismark Tax, Inc.  Isai’s practice area is concentrated in the area of tax resolution.  Isai earned his B.S. degree in Business Administration from the California State University – Northridge; a Juris Doctor from the Pennsylvania State University – The Dickinson School of Law; and a Masters of Law Degree (L.L.M) from the University of California Los Angeles School of Law.

During law school Isai worked for the Pennsylvania Department of Revenue – Office of Chief Counsel and that is where he found his love for the tax code.  Isai knew that the tax system needed improvement and that there was something that he could do to help taxpayers.  After graduating from law school, he went on and continued his studies at UCLA School of Law in order to focus more on tax and business law.

Isai wanted to build a company that would be consumer friendly and that would always give consumers what they were paying for, great tax help and full access to their attorney.  Isai saw many companies offering tax resolution services, but these companies would limit the attorney time clients received.  So that is why Bismark Tax, Inc. always gives their clients access to their attorneys.  No gimmicks, just honest help.


Isai enjoys giving back to the community and is involved in many public interest organizations.  In Los Angeles, Ca he personally volunteers to help underserved communities by providing legal aid through the Christian Legal Aid Clinic of Los Angeles, which also provides services to Homeboy, Inc.  Through a ministry in Los Angeles, Ca he is able to sponsor events where the ministry makes breakfast for women at the Downtown Women’s Center.  Other programs:
