About me

I work for victims of medical malpractice because medical malpractice is one of the leading causes of unnecessary injury and death in our society.  Far too often, our trust in the medical professionals who take care of us ends up being betrayed.  And when medical professionals betray our trust, very bad things can happen to people and families.  I feel deeply honored to represent victims of medical malpractice.  If I should come to represent you in a medical malpractice case, you will have the strong, hard-working, effective advocate that you and your family deserve.
