Mr. Denner’s practice encompasses both trials and appeals in the state and federal court systems as well as before administrative (licensing, regulatory and disciplinary) boards and agencies. His legal representation commences at the investigative, pre-indictment/pre-charging stage and carries through to appeal, post-conviction, and parole/ pre-release, as applicable.

A graduate of Yale College and Harvard Law School, Mr.Denner has been a partner in several larger Boston Law Firms during his approximately 35-year career. He and many of his cases have been profiled in local and national television shows, newspaper accounts, and magazine articles.

Mr. Denner is a member of the Massachusetts Bar Association, the National Association of Criminal Defense Attorneys, and the Massachusetts Association of Criminal Defense Attorneys. He is a former clinical Teaching Fellow at the Harvard Law School. He truly has made a motto of the National Association of Criminal Defense Attorneys – that “the Criminal Defense Lawyer is the last bastion of freedom in this country,” into a central theme of his own practice and life.
