August 10, 2008- September 22, 2026

On September 22nd, 2026 Isaac finished His race here on this earth.

On August 10th, 2008 the world was blessed with Isaac Gabriel Aguilera who was born in Greeley, Colorado and grew up in Loveland. He attended Conrad Ball Elementary School, Ellerslie Prep Academy, and later dual enrolled at Colorado Early College and Grace Academy, where he graduated in May 2026 with his high school diploma and some college credits. As a child he lived at Maple Terrace with his grandma, aunt, and parents.

At 9 years of age, Isaac, along with his siblings Destiny and Iseah, were joyfully welcomed into the Hartman Family’s home due to some hardship and loss in the Aguilera family. Permanent custody was granted to Rachel and her father, Jim Hartman. On June 13th, 2020 Rachel married Brandon Gresser who became Isaac’s adoptive father. Rachel and Brandon Gresser, though never officially adopting Isaac, cared for him for 9 years and considered him their son. Isaac was the oldest of their family of six children.

Isaac was a member at Windsor Christian Fellowship church and was baptized there in 2025. He was ranked as one of Varsity’s top 3 tennis players for Loveland High and played basketball at Loveland Classical School. Isaac traveled with the ministry King’s Kids in El Paso on three overseas missions trips and multiple years of Spring Break Outreach ministry between 2021 and 2026. Isaac worked for Brandon’s company, Legacy Builds, as a fiber optic technician during the final year of his life. Isaac was bright, fun to be with, and a natural born leader. He was loved and embraced by Brandon and Rachel and their extended family. Isaac was gentle, creative, and loved adventure. He was a faithful friend. He had a sincere relationship with Jesus and experienced the true Joy of the Lord!

Isaac was preceded in death by his fraternal grandmother Maria Aguilera, and maternal grandfather Eliseo Orozco Salido.

He is survived by his biological parents, Gabriel Aguilera and Gladis Orozco Domínguez, his adoptive parents, Rachel and Brandon Gresser, maternal grandmother Maria Teresa Domínguez Rico, siblings Destiny Aguilera, Iseah Aguilera, Analiah Mia Aguilera, Gael Gabino Agüero Orozco, Matias Elíseo Orozco Dominguez, Freederick Gresser, Beautiful Gresser, Brave Gresser, and numerous loving family, cousins and friends.
