Review Daniel Thomann

About Me


I grew up in Buenos Aires, Argentina, and Montevideo, Uruguay, and moved to Kansas City, Missouri, with my parents in 1991. I attended high school in Kansas City and stayed in Missouri for college and law school - where I was International Law Society president, and participated in the Jessup International Moot Court competition. I also worked at a North Kansas City law office, mainly on criminal defense and civil litigation. Following graduation, I worked as a legislative analyst in Jefferson City, MO, until moving to Chicago in 2004 to work as a community organizer with the Illinois Coalition for Immigrant and Refugee Rights. I have stayed in Chicago since, working as a union representative, and as a political consultant until making my way back to the law.


In 2008 I began working at a small firm in Little Village, almost exclusively on immigration cases of a diverse nature, and in January 2009 I started my own practice – focusing mainly on removal defense and cases involving criminal issues.  In the Summer of 2013 I became an associate with Maria Baldini-Potermin & Associates, P.C.


I try to devote time to pro bono work and political advocacy for immigrants. I am an avid fan of soccer and rugby, and serve on the boards of directors of the Argentina Chicago Foundation and AFOW, and on the “junior board” of Urban Initiatives.

  • Alexander M. Ivakhnenko

    I have known Attorney Daniel Thomann for a number of years and attended many CBA functions with him. I reached out to Counsel Thomann on a few occasions to discuss some elaborate immigration cases and analyze attendant issues. I was always impressed with his excellent analytical ability and knowledge of U.S. immigration law to assist clients. In my opinion, Attorney Daniel Thomann is a splendid,diligent, respectful and capable choice for handling various immigration issues for clients, not to mention his flawless use of the Spanish language.
