Avelin P. Tacon III


Avelin served as an attorney for four years with the U.S. Army’s Judge Advocate General Corps (last tour at Ft. Lewis) beginning in 1971. He began private practice in Olympia in 1975. His practice is focused on personal injury, Social Security disability, and arbitration/mediation.

Arbitration and mediation are more economical methods than litigation to resolve disputes. Avelin has been a member of the Mandatory Arbitration Panels of Thurston and Mason County since their inception. He has developed a private practice mediating personal injury disputes at the request of plaintiffs’ attorneys, defense attorneys, the state of Washington and insurance companies. He has also served as a Thurston County District Court Judge Pro-Tem since 1976 conducting mediation and pre-trial conferences for civil jury cases. However, the main focus of his practice continues to be the representation of injured people.
