Trip and fall case
I had never needed an attorney before and am so glad to have connected with Jon Marx. Even though I live out of state, Jon came to my home during my recovery. He was very thorough and kept me informed on the process. Both he and Attorney Ted Kaplun worked hard for what was an excellent and fair settlement. I am more than satisfied with Jon and Ted and would highly recommend them to anyone in need of legal services.

Slip and fall case
jonathan had help me with a slip and fall case 2 years ago. He's a good fighter. Never hold punches when he ready to fight for you. In my eyes his like a boxer like Mayweather. And he will tell you if he can or can't take your case. but most likely he will take you case. Jonathan is a pitbull when it come to help his clients

HIGHLY RECOMMEND Jonathan Marx!
It was my first time ever needing a lawyer in my life. I chose right to go with KaplunMarx. Ted and John have helped me every step of the way. I didn't know what to do with my situation...Ted and John were always available, responded in a timely manner, and very professional. I had the pleasure of working with both Ted and John. My life is now back to normal thanks to KaplunMarx! I HIGHLY recommend anyone who needs a lawyer to pick KaplunMarx!

Professional, classy, sympathetic
Jonathan Marx had agreed to help me out with a very unusual matter on a contingency basis. It was a case of a poorly done plastic surgery procedure and the surgeon (Dr. Robert Mirabile of Blue Bell) refusing to make corrections, making it a case of contract breach. We wanted to recover money I had to pay someone else for a corrective procedure. Jon had put in a decent amount of time and effort into communicating with me, reviewing documentation and attempts at negotiating with the opposing attorney ~ a guy who was basically a pig in a nice suit. As the other side refused to settle, Jon also represented me in court and I thought that he presented a solid case to the judge. Unfortunately, we lost the case but not for lack of effort on his part, and not because the defendant was right. Jon personally followed up with me by phone after the verdict and explained my other options. He told me that the defense had warned him months earlier that they would appeal a favorable verdict, which impressed me because Jon had known that getting paid for this case would be tedious, yet he still pursued it. I'd hire him again in a heartbeat.

Car Accident Lawyer
Mr. Marx helped me through a difficult injury case, a few other lawyers wouldn't even take my case, but Mr. Marx fought for me. I will send anyone I know to KaplunMarx if they have a personal injury case. Thank you Mr. Marx!

Slip and Fall Settlement, Very Happy
Mr. Marx helped me get a large settlement for a slip and fall injury in which I was hurt badly. He was knowledgeable about the process, but unlike other lawyers I have dealt with, he was thoughtful and caring throughout my ordeal. Mr. Marx is a wonderful lawyer and I would recommend him to anyone who wants a Lawyer who cares.
