About Attorney William Pesch


Knowledge. Experience. Empathy.





Upon graduating from college in 1976, I came to Guam as a high school Biology teacher. In 1979, I left the teaching profession to pursue a law degree from the American University Washington College of Law in Washington D.C. Upon graduating from law school in 1982, I clerked for Judge Joseph Ryan, a senior judge for the Washington D. C. Superior Court. I returned to Guam in January 1983, and over the ensuing years worked for a private firm, as a public defender, and as the legal counsel to the Guam Department of Education.

In 1995, I established the Agana Legal Clinic, a private law firm specializing in meeting the diverse needs of Guam's families, civilian and military alike. In 2014, I renamed my practice the "Guam Family Law Office" where I continue to offer a wide range of legal services for Guam families, and to those residing elsewhere who choose to obtain a Guam divorce. I was raised in a military family, facing many of the same challenges experienced by all military families. For this reason, I am very empathetic to the special needs of military members and their dependents and I have a vast knowledge of both Guam and federal laws that impact military families.

I also offer professional mediation services for family-related matters through Pacific Arbitration and Mediation Services.
