I have been practicing law for almost 17 years now in the field of personal injury, eight of which have been here in Jefferson County.  I spent the first nine years of my career working for the insurance companies in personal injury cases, and learned that rarely were the insurance companies willing to pay injured people the true value of their claims.  I found my passion in helping people through the difficult waters of making a personal injury claim or worker’s compensation, and insuring that they receive appropriate and adequate compensation for the damages they have suffered, not in saving the insurance companies money.  My team and I stand ready to use our collective knowledge and experience to help you through this process.
