Jon is a trusted advisor and counselor to a wide variety of private and public corporations. He often serves as outside general counsel on behalf of clients including manufacturers, value added distributors, real estate developers, private equity groups and their portfolio companies, family offices, financial institutions and technology companies, among others. Jon Chairs KJK’s eCommerce Practice Group, helping clients protect their brands and profit margins when selling on Amazon and other e-commerce marketplaces. Jon is also part of KJK’s leadership team, serving as Hiring Partner to oversee the recruitment and development of top talent in the firm.

In his role as outside general counsel, Jon helps privately held, family-owned companies protect and grow their businesses, leveraging KJK’s full-service corporate platform. His extensive background in business litigation includes contractual issues, trade secrets and securities fraud in federal and state courts. Jon assists businesses in the enforcement and defense of restrictive covenants, including non-compete/non-solicitation agreements, and advocates 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 proactive thinking, responsiveness and efficiency. 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 and inner-city Cleveland, including Saint Martin de Porres High School, MetroHealth, the Greater Cleveland Sports Hall of Fame, 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.
