About me

We are passionate about representing our clients' interests and getting the best possible results for them.  Our success is a matter of public record, and we have obtained record high verdicts in numerous cases throughout Ohio and other states.  We have three nurses on staff, a medical library and computerized access to all published medical literature in the world.  This allows us to retain the very best medical experts in the country to assist our clients in their cases.  Because of our success and reputation for integrity, we are often consulted by physicians and their family members when they themselves have been the victims of medical malpractice.  We do not advertise on television or phone books.  Our clients are referred to us by other attorneys who are familiar with our professional experience, success, and aggressive representation on behalf of our clients.
