Judge William C. Birdsall was born in Idaho and raised in Missouri.  He graduated from the University of Missouri-Columbia School of Law in 1973 and was admitted to the Missouri Bar that same year.  After a brief stint in the United States Army as a Second Lieutenant, he moved to Farmington, New Mexico, in 1974. 

    Judge Birdsall was admitted to the practice of law in New Mexico in 1975.  His practice involved criminal, civil, domestic, and administrative litigation.  During that time, he was active in civic, fraternal and charitable organizations and worked with others to establish the Safehouse Program for abused children at Childhaven.

    Judge Birdsall served a term as San Juan County District Attorney from 1985 through 1988, and was elected as President of the New Mexico District Attorneys’ Association during that term.  He took office as District Judge, Division I, in January 1999, and was elected Chief Judge of the Eleventh Judicial District by his fellow judges in 2002 and served until 2009.

    In addition to his duties as Chief Judge and his juvenile, civil and domestic caseload, Judge Birdsall is actively involved in the court’s Self-Represented Litigants Program, Juvenile Drug Court, and Grade Court.
