Luis John Castro

He previously worked as a teacher’s assistant in the CNMI Public School System and as an Administrative Assistant at the Northern Marianas College.

While in office, he championed destination enhancement within the villages, proper treatment of ancestral remains and increased awareness of medicinal plants. He is also an active member of the Association of Mariana Island Mayors, Vice-Mayors and Elected Municipal Council Members, and has made strides in promoting inter-island collaborations between village leaders in all four of the Marianas’ jurisdictions.

He was sworn into office on January 14, 2019. After assuming his duties, he was appointed to serve as Chairman on the House Committee on Federal & Foreign Affairs. His first bill, HB 21-23 HD1, aimed at including the CNMI in the Emergency Management Assistance Compact. This measure allowed the Commonwealth to be included in the agreement which includes all fifty states, Puerto Rico, U.S. Virgin Islands, and Guam, enabling states and territories to share resources during natural and man-made disasters, including terrorism.

Governor Ralph Torres signed the bill into law on September 3, 2019, officially becoming Public Law 21-7.

He was elected to the Northern Mariana Islands House of Representatives in the 2018 Northern Mariana Islands general election.

In April 2018, Castro announced his intention to seek a seat in the House of Representatives for Election District 1, the CNMI’s largest election precinct encompassing nearly the entire eastern and southern portions of Saipan in the upcoming general elections

Originally scheduled for November 6, the elections were postponed for two weeks following the devastation brought upon by Typhoon Yutu. On November 14, 2018, Castro was elected to a two-year term in the House of Representatives, finishing fifth out of thirteen candidates.

In 2016, he ran for public office anew as a candidate for the Saipan & Northern Islands Municipal Council, a form of municipal level government in the Northern Mariana Islands. He won election and was sworn in on January 9, 2017, becoming the youngest person to serve in that capacity in the council's history. After taking office, he was elected Chairman of the council, the equivalency of a vice mayor position.

By law in the CNMI, Castro in his capacity as Chairman served as Acting Mayor in the event of the absence, vacancy, or death of either the Mayor of Saipan or the Northern Islands. This was the case in February of 2017 when Northern Islands Mayor Francisco Jerome Kaipat Aldan passed away suddenly while in office. Castro served as mayor in the interim until the appointment of Vicente Cruz Santos, Jr. to fill out the remainder of Aldan's term.

In 2017, CNMI Governor Ralph Torres conferred on him the Governor’s Humanities Award for Preservation of Traditional Cultural Practices, in recognition of his work in promoting culture through song, chant, and dance.

In 2014, he worked for Governor Eloy Inos as a Public Information Specialist under then-Press Secretary Angel Demapan. He continued in this capacity under the administration of Governor Ralph Torres until his election to the Legislature in 2018.

Since 2002, he has been a strong advocate of cultural enrichment through performing arts. In 2004, he was a performing arts delegate for the Northern Marianas in the IX Festival of Pacific Arts which was held that year in Palau. He currently serves as creative director of Guma' Simiyan Manaina-ta, a local dance troupe aimed at showcasing Chamorro culture through performing arts.

He graduated from Marianas High School in 2001 and attended Northern Marianas College where he majored in Business Management and Liberal Arts.
