Areas of Practice

Jonathan D. Mester

Managing Partner

Jonathan D. Mester focuses his practice on representing victims of medical malpractice, including obstetrical malpractice cases in which the baby suffers severe deficits at birth including Cerebral Palsy and Erb’s Palsy. Jonathan also handles construction accident cases involving serious injury and death.

Jonathan joined Nurenberg, Paris, Heller & McCarthy in 1998 as an associate and today is the managing partner with the firm, and a member of the firm’s board of directors. He is a member of the Million Dollar Advocates Forum. Jonathan has also been selected for inclusion in Ohio Super Lawyers® by Law & Politics Media since 2010. In 2021, Jonathan was included in The Best Lawyers in America publication for both medical malpractice and personal injury litigation.

Jonathan is proud to represent individuals who need assistance in taking on hospitals, corporations, and large insurance companies. He is most proud of the jury verdicts he has obtained. Jonathan has obtained multiple jury verdicts more than a million dollars, including the first medical malpractice verdict in several years in Columbus, Ohio on behalf of a four-year-old girl in 2013. In each of these cases, the wrongdoer offered little or nothing to settle the case, leaving Jonathan’s clients no choice but to take the case to trial.


  • “Due to the severity of my daughter’s accident, I had attorneys actively reaching out looking for our business. I did so much info gathering and research to ensure I chose the right person and firm to represent my family, Jonathan Mester was the best choice I made. He listened to our needs. He understood my concerns and allowed me to ask thousands of questions to ensure I was comfortable with the process. He fought tirelessly to make sure we were taken care of. Couldn’t be happier, highly recommend Jonathan Mester!”

    Former Car Accident Client, AVVO Review

  • “My experience with Nurenberg Paris was very positive during a tumultuous time for me. Jonathan Mester is a kind and compassionate person and he handled our case like a true professional. The staff at Nurenberg Paris always treated us with dignity and respect. Phone calls and email were returned promptly, and we were kept abreast of the cases as it unfolded. His case manager, Rachel, was great to work with and very professional. When the time came, we were well informed of our options in the case and what the anticipated result would be. While I pray, I never need this type of service again, I would not hesitate to reach out to him should the need arise.”

    Former Client

  • “Jonathan Mester worked with my Lawyer who was Tom Mester. They worked great on my case. If I needed another lawyer in this area, I would definitely use this team. They work well together and I was very happy with my services.Tom Mester and Jonathan Mester are a great team!”


  • “Jonathan was kind, compassionate and extremely professional, yet personable, and believe he gave excellent advice. He presented options related to agreeing to a settlement or going to trial. Given my family’s circumstance, settlement was the best option. Both Jonathan and his firm would receive an excellent overall recommendation from myself and family.”


  • “I took some time to decide whether or not to file a lawsuit against a woman who had hit me back in September of 2019. I only decided to after she was giving me the run around about her insurance handling the claim. I finally contacted a dear friend of mine who is a semi-retired criminal lawyer, who recommended Nurenberg Paris. I was assigned to Jonathan Mester for my claim and his case manager, Rachel Neneckay, both were very kind and helpful. Their turn around time to respond to an email or phone call was also very impressive, I work for the Cuyahoga County Common Pleas Court and I know from doing my job that the turnaround from lawyers can be very stressful for a lot of people. I would recommend them to others.”

    Former Car Accident Client, AVVO Review

  • “Jonathan was readily available to me with answers to all my questions. When we had to meet he was prompt and cordial. Everything he explained to me was clear and there were no surprises.”
