Program Director: Michael C. Panebianco


Michael has returned to the Southern Tier, a place he has called home his entire life, to represent injured workers. Michael is passionate about counseling injured workers because his father suffered a career ending work injury many years ago. As a result, he has a keen understanding of the physical, emotional, and financial toll that a serious physical injury may have on a family.

Michael will also focus his practice on criminal defense. He understands the negative effect that a criminal conviction can have on a person’s life. In law school, he interned at The Center for Community Alternatives, where he counseled individuals in an effort to help them overcome the barriers to employment and education that they faced due to their prior criminal convictions.

Michael worked as a law clerk with Lewis and Lewis, P.C. during the Summer of 2015, and he is excited to return as an associate attorney.
