Daniel J. Lanahan was born in Brooklyn, New York at the beginning of World War II. After three years active duty in the U.S. Army and college, he worked as an insurance claims investigator and manager while attending law school.
During his 35 years in the practice of law, he has often pursued other interests. His entire legal career encompassed two law firms, one for 26 years and the firm he founded, Lanahan & Reilley LLP, in 1997.
He also worked as a police officer, including stints as a patrolman, detective and legal officer for a San Francisco Bay area police department. He taught the laws of search and seizure, arrests and the use of firearms at a police academy. His published book on those subjects was utilized by law enforcement. In the 1980’s and 1990’s he handled mass civil litigation in many states, was a board member and President of Concern America, an international aid organization, and relocated his law practice from San Francisco to Sonoma County.
During the 1990’s, Mr. Lanahan nationally coordinated the L-Tryptophan liability litigation nationwide, resulting in the Japanese manufacturer indemnifying his 158 U.S. food supplement and vitamin industry clients for an amount in excess of $3 billion.
After starting his present law firm, the largest in the North Bay and North Coast area of California, he served on many non-profit and for profit boards of directors including the North Bay Council, California Rural Broadcasting Corporation and the St. Joseph Health System of Sonoma County, all of which he also chaired.
Mr. Lanahan teaches a course on Legendary Trials at Sonoma State University, Empire Law School and San Francisco Law School. This work is a product of that course.
