Charles C. Tyrrell

Charles Christopher Tyrrell – Mr. Tyrrell is a partner and founder of the firm.  He was born and raised in Louisville, KY.  Mr. Tyrrell graduated with an engineering and math degree from Vanderbilt University, and then spent about a year in New York City working with a major law firm on an antitrust case.  He then attended the University of Miami in Florida, where he obtained his law degree.

Mr. Tyrrell is passionate about immigration law for several reasons.  His paternal grandfather, a former British diplomat in China, immigrated to the United States in the 1950s.  As such, Mr. Tyrrell is a second-generation immigrant.  Mr. Tyrrell’s grandfather taught him a valuable lesson in life.  Although his grandfather was a British diplomat and a graduate of one of the most prestigious universities in the world, when he immigrated to the US, Mr. Tyrrell’s grandfather started over again, taking an entry-level position at a department store.  It was him willingness to work hard that allowed him to eventually become an executive for the company.
