Jon is a talented litigator and trusted counselor to a wide variety of public and private corporations that include manufacturers, real estate developers, property managers, hedge funds, private equity portfolio companies, financial institutions, distributors, physician groups and technology companies, among others. Jon is also part of KJK’s leadership team, serving as co-hiring partner along with Jim Lane to oversee the recruitment and development of top talent in the firm.

He’s skilled in the most complex client matters involving business torts, securities, trade secrets and contractual issues in federal and state courts. Jon’s experience includes assisting businesses in the enforcement and defense of restrictive covenants, including non-compete/non-solicitation agreements, and advocating on behalf of clients seeking and defending against temporary restraining orders, preliminary injunctions, and other forms of emergency relief. Many of Jon’s clients rely on him for risk management counseling and oversight of their claims handling processes. Jon also advises businesses in out-of-court resolutions, including mediation and arbitration.

Jon’s client service philosophy prioritizes accessibility, responsiveness, and efficiency. He’s prized by clients for being thoughtful but tough. A history buff, Jon often applies lessons of the past when helping clients strategize, assess risks, and engage in long-term thinking.

After four years practicing law in Washington, D.C., Jon returned to his hometown of Cleveland in 2012. His love for the city compels him to invest his civic energies with organizations that serve young people in Northeast Ohio, including the Boys & Girls Club of Cleveland, College Now Cleveland, and his alma mater, Saint Ignatius High School. He’s also a lifelong Cleveland sports fan and the grandson of long-time Cleveland Browns offensive tackle and place-kicker Lou Groza, who was enshrined in the Pro Football Hall of Fame in 1974.

“I think creatively and work proactively in order to obtain outcomes that benefit my clients and their businesses.” – Jon W. Groza
