When I started to practice law 35 years ago, my father, also a lawyer, offered me some thoughtful and exceptionally valuable advice: listen carefully, do your homework, and above all, maintain a sense of humor – because you are going to need it. I have to admit that Dad was right and his wise words have resonated with me during my entire practice.  Listening attentively to my clients and meticulous preparation are indeed the hallmarks of success.  And, finding a way to put clients at ease establishes approachability, confidence, and most importantly, trust. Working closely with each client, I make sure that I identify the specific goals and strategies of any legal case or matter.   

I am that lawyer who gets right on the phone with clients even on a Saturday because I understand that sometimes questions just can't wait for regular business hours.  I am that lawyer who may be dressed casually around the office (suits are for the courtroom) but make no mistake, I am always a passionate advocate for my clients, no matter what I am wearing. 

 As founder and managing partner of the Katz Law Group, P.C., located in Marlborough, Massachusetts, my practice includes but is not limited to complex real estate litigation, employment disputes, premises liability defense, franchise and business litigation matters. I am cum laude graduate of Brandeis University and I received my law degree from the New England School of Law in Boston, Massachusetts where I was a member of the law review.

On occasion, plaintiffs and defendants from the opposite side of cases have gone on to hire me when the matters have concluded.  Some have said, “We need a guy like you.” Those words are reinforcement and reward to a lawyer like me.
