Penny Cooper, of Counsel

Penny Cooper spent her legal career concentrating on criminal defense and is of counsel to Cooper, Cooper & Morris. Renowned for her cross-examination skills, Penny has secured acquittals and reduced sentences in a number of high profile cases during her career.

Penny, along with Cristina Arguedas, won the acquittal of Michael Blatt in the “crossbow” murder case in 1990. In 1998, Penny convinced the prosecution to dismiss the charges in the “repressed memory” case of George Franklin. In 2000, Penny, again through her art and skill of negotiation, convinced the prosecution to dismiss the case against Dr. William Liebman, a physician in Marin County who was accused of diluting vaccines given to children.

In 2010, Penny Cooper was inducted into the Trial Lawyer Hall of Fame by the California State Bar’s Litigation Section.
