The Honorable Peter Charles Siguenza, Jr., was the first Chief Justice of the Supreme Court of Guam established in 1996 by the Organic Act of Guam.  Prior to his appointment as the first Chief Justice for Kotten Mas Takhelo Guåhan, Chief Justice Siguenza served for twelve years as a trial judge in the Superior Court of Guam.

Born on Guam in 1951 to Captain (USMC-RET) Peter C. Siguenza, Sr. and Barbara Louise Bordallo, Justice Siguenza graduated from Father Duenas Memorial High School before earning his B.A. in Government from California State University in 1976. While at Cal State, he was a member of Phi Sigma Alpha, the National Political Science Honor Society. In 1980, Justice Siguenza received his law degree from the McGeorge School of Law at the University of the Pacific in Sacramento, California, where he also served as President of the Asian Law Student Association from 1977-78.

Justice Siguenza was appointed as a Designated Judge in the District Court of Guam, in addition to Designated Justice in the Supreme Court of the Federated States of Micronesia. He has been active in numerous bar, community and civic organizations for most of his life, including Chair of the Supreme Court of Guam Rules Commission in 1993 and Chair of the F.D.M.S. Board of Trustees in 1991. Justice Siguenza was a member of the California Bar, the Guam Bar and the Commonwealth of the Northern Marianas Bar.

A self-described “amateur bluesman,” Justice Siguenza taught guitar at the former Guam Academy of Music and Arts in Agana in the early 1980s. From 1987-89, he was enlisted as a studio musician for the group “Chamorro” to make “Ningai’an Pumara,” the first locally produced contemporary music compact disc containing a collection of original Chamorro songs.

Justice Siguenza married his late wife, Joleen Taitano Rios Siguenza in 1969. Chief Justice Siguenza has one daughter, Dawn Rene Siguenza Blas, four grandchildren, and one great-grandchild. He married Kathy Fokas Siguenza on November 17, 2017.
