Daniel Warren Thomann
About Daniel
Biography
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 began working for Maria Baldini-Potermin & Associates, P.C., and in May 2015 I re-launched my solo practice, daniel thomann, 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 the Chicago Lawyers Rugby Football Club, the Spanish language advisory board of Illinois Legal Aid Online and on the “junior board” of Urban Initiatives.

Awesome!!!!
This lawyer took time to write and answer my question. Unlike the other lawyers where they just say "you should consult an attorney". That's why there is website like this to seek assistance for those who are legal experts. Thank you, Mr. Thomann.
