About Me

     I am a life long resident of Northwest Indiana with strong ties to the community.  Growing up in Gary and Merrillville, I graduated from Andrean High School in 1980.  I then attended Indian University in Bloomington and graduated in 1984 from the Business School with a BS in Finance.  Indiana University is also where I obtained my law degree, graduting in 1987. 

      I returned to Merrillville to start practice with my father, Nick Thiros that same year.  Being a prolific trial lawyer, I co-counselled many cases with him and soon began doing trials on my own.  I have practiced in various fields of law in addition to personal injury,  including criminal, family, commercial and governmental.  Over the years my case concentration developed in personal injury.

     I help my clients through the difficulties and confusion of the personal injury experience.  I deal with the insurance companiens and their adjusters.  I obtain all medical records and bills necessary for the claim.  My clients have access to me for questions and concerns through my personal cell phone and email. I take all other appropriate actions to ensure a fair outcome of the case so my clients can concentrate on their healing process. 

     I am here to help you.
