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. Mr. Genish oversees each and every case personally and carefully selects his cases to ensure proper and individualized attention is given to every client without compromise.

After you’ve selected your legal partner, your attorney becomes intimately involved in your life, and often in situations that are painful or sensitive in nature. You want someone who will conduct themselves with honesty and integrity while representing your best interests and keep you informed as your case makes its way through the system.

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.
