Practice Areas

For over thirty years, I have tried almost every type of case that has been charged. I have been in trial on over fifteen homicides, including cases involving DNA, life without parole, impaired mental condition and whether or not the client was competent to stand trial. I utilize mental health professionals, forensic experts and investigators as the case demands. There are clients who prefer not to go to trial and that is their decision. I will make sure that each client knows their opinion is critical in determining in which direction the case will go.
