About Ronald Dinan

Criminal Defense Attorney With Over 12,000 Cases Handled

Ron Dinan was raised in Fort Lauderdale and graduated from St. Thomas Aquinas High School in 1964. He began his college career that year and two years later joined the U.S. Marine Corps. Prior to going to Vietnam, Ron spent six months at Camp Pendleton in Southern California; it was during this time that he made the decision to eventually move to California.

Ron served with the First Battalion, 5th Marines, in the Quang Nam Province outside of Danang in 1967. After returning from Vietnam, he was honorably discharged from the Marine Corps in 1968. Returning to college, Ron graduated with a Bachelor of Science degree from the University of Miami in 1971 and continued his education by acquiring an MBA and then graduated from law school with a Juris Doctor degree in 1974.

Moving to California, Ron opened his first office in Santa Rosa in 1976 and, over the years, his firm has expanded to six offices in Santa Rosa, Napa, San Rafael, Lakeport, Ukiah and Eureka. His firm is exclusively a criminal defense firm and has handled over 12,000 cases.

In March 2013, Ron founded the first VA Free Legal Access Clinic in California providing free legal advice and representation to veterans at the Santa Rosa Veterans Administration office.
