In my professional career, I have been privileged to represent professionals in various disciplines and a variety of business enterprises. Nonetheless, the work that I found most rewarding has been in the area of private placement adoptions. I have been blessed and privileged to facilitate the adoption of dozens of children through my representation of friends, colleagues and clients, including single mothers, for the past 30 years, guiding them through the agency and probate court process to ensure that each child would be united with its adopted parents shortly after birth.

Mario served as Managing Partner of Reminger Co., LPA from 1990 to 2005. A few of his many accomplishments include his vision to successfully expand Reminger from 45 attorneys in two offices to more than 125 attorneys in eight offices. An Italian immigrant, Mario's hard work, entrepreneurial spirit and sense of fairness makes him a frequently requested mediator by both plaintiff and defense attorneys for complex litigation matters. 

Mario has always maintained an eclectic legal practice. He enjoys representing businesses and professionals including attorneys, doctors and accountants. In fact, he is frequently hired by other attorneys to assist them in resolving their own legal matters.

Most recently, Mario has been honored with the 2018 William K. Thomas Professionalism Award from the Cleveland Metropolitan Bar Association, as well as with ORT America's 2018 Jurisprudence Award. Mario has been recognized and included among the 'Best Lawyers in America' for the last 25 years. He has been featured as one of the 'Leading Lawyers' by Inside Business Magazine and is a member of the Federation of Defense and Corporate Counsel and Defense Research Institute. He is also a faculty fellow for the National Institute of Trial Advocacy and a life delegate of the Eighth Ohio Judicial District. He frequently lectures to peer groups on various issues covering professional liability, trial tactics, litigation management, and Alternative Fee Arrangements.
