My mom fell down a flight of stairs due to a slippery surface and the handrail was broken at the time so she had nothing to grab onto to catch herself. She sustained serious injuries to her back. John Mennie took her case and handled everything for her. He was very easy to talk to and made himself available when we had questions. He was successful in reaching a settlement that my mom was happy with. When you hire John Mennie you are hiring a lawyer with years of experience in personal injury and also a patient and kind individual who shows true compassion for your situation. We would highly recommend him.

Honesty, legal knowledge. aggressive representation, and communication were basic requirements in my search for an attorney. With John Mennie I found all of that and something else. He cares deeply about his clients, and it made a huge difference in the quality of the legal advocacy we received. His dogged persistence worked through a complex liability matter to a satisfactory resolution. We are very grateful for his untiring efforts on our behalf. - A. Sydney Lekach

It has been almost 4 1/2 years since Mr. Mennie’s law firm took on our case. After severe injuries sustained by my wife and me, John Mennie and his highly professional staff took care of our situation on multiple levels. Firstly, they got us to where we needed to be in terms of medical care in the most expedient manner. We both required assessment by surgeons and pain management providers who are leaders in their fields. Next they accomplished the goal of obtaining a fair settlement in our case. I trust Mr. Mennie for any legal matter . As a medical professional myself, I attest to the fact that you are in good hands for all your legal matters with John Mennie.

Looking for a lawyer who will be a WARRIOR for you, John Mennie was that man for me. My story is, I had no fight in me after my injury. I just wanted to put things behind me and settle quickly, thank goodness John reasoned with me to just hold on abit and let him do his job. THAT WHAT HE DID JUST LIKE A WARRIOR! Within a short period of time he presented me with a settlement offer which was DOUBLE the amount that another attorney said I would get. If he takes your case you will be a winner. $$$$$ Thanks John, and congratulations with opening your expanded new firm.

John Mennie and his team have helped us through the most difficult times of our lives starting November 2019 automobile accident. They are highly professional, very caring, warm, and meticulous. They professionally worked-through the toughest time we all went through - Covid in 2020, while all the time keeping our mental and physical well-being at the fore front, as the process was underway. They have fought to get the highest settlement possible. I would not trust any team other than John Mennie with my life. If you ever need an attorney with a heart, look nowhere else but to John Mennie and his team.

What can I say about Minnie and Heizler? I had Greg for an attorney. I must say, in my experience I gained a lawyer and a friend. Not only did he get me the maximum for my case, I referred 4 other friends and family to the firm and they were more then satisfied with their outcomes. When they said, “They was going to fight for me?” They took the Gloves Off and went Bare Knuckles!!! 🥊

After a serious injury in which I was laid up and out of work for 6 months, I need a personal injury attorney. I was recommended to John Mennie by a friend.

He and his staff were professional, easy to talk to, and promptly returned calls when needed. If you ever find your self needing a personal injury attorney, I would highly recommend John Mennie and his team.

MENNIE HEIZLER LAW FIRM went above and beyond in resolving my car accident case. The entire team was proactive in every step of the process- doctors appt reminders; getting records, and follow up with each action. The communication between the whole team was above expectations and the compassion, empathy, and professionalism that I received from the team was something I don't think another law firm would provide. I was recommended from a peer and I encourage you to work with this team for any personal injury case.

Car accident case. I left a large law firm to sign with Greg at Mennie Heizler! My doctor initially recommended a large law firm in his complex. I made the error of signing shortly after the accident, without investigating. I will never make that error again. Trying to get a simple return call from the lawyer the big firm assigned me, was like pulling teeth. I was frustrated. Greg Heizler was recommended by a friend in the insurance business. The friend said Greg was well respected in the insurance industry. It sparked my interest! So far, moving my case to Greg Heizler has been the BEST legal decision I’ve ever made! Greg and his team have been communicative and very responsive throughout the process. To me, THAT effort in simple communication, reflects the utmost care for each of his clients cases. I knew I was in good hands. My case has yet to conclude, as it’s in standard delay mode. However, I have never regretted my decision to leave that God awful large firm to sign with Greg at Mennie Heizler. From day one and now 2yrs later, he and his team have never let me down. In my opinion, communication is key to building trust. To build trust in a good lawyer, you do your homework, investigate the lawyers credentials, review any avail previous case data, and then reach out to test interactions for style and fit. Greg Heizler and his team have out shined every law firm I interviewed. I don’t care how many big money cases you’ve won, as much as I care that MY case is just as important, and this team makes me feel that way each time we reach out to each other. I am in good hands. You will be too. I highly recommend Greg Heizler and his team, they have never let me down.

After an accident my insurance company was beyond frustrating to deal with—they just wanted me to go away and I was in a lot of pain. They told me I had not sent in documentation when I did multiple times, refused to forward information to the other insured’s company for reimbursement and just wasn’t a pleasant experience. I decided to contact Greg Heizler and it was the best decision I ever made!! They got to the root of my pain and put me in with the best doctors! You’re not just a number or someone they are representing. You’re treated as a person!! Unfortunately I have another case with them but I know I’m in great hands!!!

Our experience with John Mennie and Dave Cohen was unbelievable. They are the most dedicated, educated and compassionate attorneys. They settled our lawsuit extremely quickly and their clients are kept up to date through the entire litigation process. They were able to get us a much larger settlement than expected. If you’re in need of the best, these are your attorneys.

John was representing my mother in an uninsured motorist/personal injury lawsuit stemming from an automobile accident. She passed away 3 months later due to her injuries and it became a wrongful death case as well. He began representing her estate which included myself and my sister. John built a very trusting relationship with my mother, was saddened by her passing, and quickly built that same relationship with myself and my sister. He cares about people first as well as the law and seeking justice/compensation. John is a great lawyer and person. I could not recommend him more highly and we are more than satisfied with the work he did for us and the outcome of my mother's case. He handled every facet from dealing with the medical companies, financial institutions, and insurance companies and made the process as easy as possible for us during a tough time in our lives....Thank You John!

John Mennie is hands-down one of the best attorneys in New Jersey. He handled my case with real care and professionalism from start to finish. He always kept me updated, explained everything clearly, and fought hard to make sure I was treated fairly. You can tell he actually cares about his clients. If you want someone experienced, responsive, and tough when it counts, I highly recommend him.

John E. Mennie is not only my lawyer, he is someone that I can call a friend. He and his associates will treat you like family. This is my second time dealing with John E. Mennie. The first time was involved in a car accident on 2016 and I received a great amount of money from that accident. This time I was involved in another in 2024 and I received and even greater amount.To be quite honest, I can’t see myself going to another lawyer unless he retires and I’d still ask him who I should go to for legal advice. Mennie & Heizler are the best. I would recommend that if you have an accident or any else, you should see them.

John Mennie and his team were a dream to work with. I had a complex personal injury suite that would have been impossible to pursue independently. His team guided me on every step and resource and took on anything I found challenging with grace. They set expectations early and I was able to see success through their plan. I highly recommend John Mennie and his incredibly diligent team. They made a really stressful situation feel far more manageable. I could not be more grateful for their work on my case.

The attorneys lawyers go to. As an attorney myself, it was comforting to know how many other lawyers and judges recommended Mr. Mennie and Mr. Heizler and it’s clear to see why. He and his staff were completely on top of my case from beginning to end. I would strongly recommend them to anyone I know.
