Yarshenko & Heidinger are a team of three lawyers who strive to zealously represent all their clients regardless of the nature of the criminal charge.

The lawyers of Yarshenko & Heidinger have a very broad range of experience and continuously work to be apprised of any new developments in criminal defense.  Counsel meet on a weekly basis to review new case law and the impact any such jurisprudence may have on matters the firm has before the courts.  The members of the firm attend criminal law conferences, complete on-line seminars/courses and consult with experts (i.e. Pathologists, DNA) to remain at the forefront of any developments that may have implications on the successful defense of a client.  

Yarshenko & Heidinger takes pride in being a client’s advocate, legal expert and first, and only, line of defense when they are facing the massive resources of the state.  We are genuinely interested in our client’s well-being and often forge professional relationships over the course of a matter that remain after a matter has come to conclusion.
