About me

I am a skilled and experienced criminal defense lawyer, and I understand how important each client's case is to them. If you choose me as your lawyer you will have an attorney who listens to you, fights hard for you and give you good, honest advice.  Clients trust me because they know I fight hard and I'm on their side. They know I work their cases thoroughly so I will be prepared and ready for trial if that's the best way to resolve their case.  If you are looking for an accomplished and trustworthy criminal defense attorney who will fight hard for you and give you good, reliable advice, give me a call. I handle criminal cases in state and federal courts throughout Oregon and the Pacific Northwest.
