Theresa Aguilar


I was born and raised in the Inland Empire. The faith of my grandmothers and the commitment of my mom to church paved the way for me to commit my life to Christ at 16. It’s been an adventure ever since! I found my passion by serving the house of God while in youth, doing missions as a young adult, and serving as youth leader and Sunday school teacher throughout my college years. A study abroad year at Uppsala University in Sweden led to a two-year life transforming experience at Livets Ord Bible Center. Upon returning home, God led me to The Rock where I have been a member since 1999. I completed my studies at Cal State University, San Bernardino that year with bachelor degrees in Biology and Liberal Studies, and began teaching chemistry at Fontana High School. As part of The Rock family, I served in Women’s, Small Group and Singles ministries, helping to raise up leaders and develop ministry teams. I earned a Master of Divinity in Practical Theology from Regent University in 2010, followed by a two-year Pastoral Internship at The Rock. I have served on the TRBC faculty since 2012 and was ordained in 2013. I am currently working towards a Doctor of Ministry at Fuller Theological Seminary with a focus on kingdom leadership and spiritual formation. After 21 years as a chemistry teacher, I retired in 2020 to join the pastoral team at The Rock full-time. It is my greatest honor to invest my life equipping believers to live out their Kingdom assignment.

Life Scripture

For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart. - Hebrews 4:12


Travel, slow coffee on a busy street, and historical fiction.
