Our History


Trinity Presbyterian Church began in November 2015 with a few families from Andersen AFB in the village of Yigo.  Pastor Tim Beauchamp planted the church in his home, and the congregation began to grow.


In 2017, Trinity moved to the facilities of Agana Heights Baptist Church and began worshipping on Sunday evenings.  Both churches have sought to enjoy a spirit of unity and harmony by maintaining their historical theological affirmations.  Pastor Tim serves as the interim pastor of AHBC on Sunday mornings with the preaching of the Word.


Trinity Presbyterian Church is a modest-sized congregation of military families and local families.  We look forward to meeting you and growing together in the grace of our Lord Jesus Christ!
