Who We Are?

Blackstone Law is a legal firm of industry veterans with experience in employment law, personal injury/wrongful death, and business litigation. Since 2008, our founder, Jonathan Genish, has had the singular goal of serving his clients by generating excellent results.

We are known for our aggressive and persistent approach to every case. Our clients are more than numbers, they are people that are facing terrible circumstances, and we are here to stand alongside them while navigating their case through the legal system. We believe that everyone deserves the strongest legal representation possible, regardless of what they can afford to pay. As a result, we take all employment and personal injury cases on contingency.
