Roberto Davila - Manager
After working with our team from 2022 to 2025, Roberto returned in September 2026 after a year and a half gaining outside experience. He began his automotive career in 2001 as a lube tech, advancing to smog inspector, service advisor, and service manager. Roberto holds an Associate degree in Service Management and a Smog License from WyoTech/Sequoia Institute in Newark, California. Originally aspiring to be a doctor, he found a similar purpose in automotive care: diagnosing root causes and solving problems to help people. He is committed to customer education, honest service, building trust, and reframing industry stereotypes. Outside of work, Roberto and his wife have two daughters in high school, Maya (a junior) and Magdalena "Maggie" (a freshman). They also have Coffee, a five-year-old pandemic-adopted rabbit who loves apples and bananas. Roberto's interests include golf, disc golf, backpacking, hiking, reading, emerging technologies/AI, and gaming. A dedicated sports fan, he follows the San Francisco 49ers, Golden State Warriors, San Francisco Giants, Chelsea FC, Bayern Munich, and Chivas. Roberto returned to Allied Auto Works because of its collaborative culture, strong client focus, seamless team communication, and modern digital tools—like texting digital inspections and estimates. Ultimately, the supportive environment and focus on genuine, long-term customer relationships drew him back.

Shane Aberg - Shop Assistant
Shane joined Allied Auto Works in June 2019 as a Shop/Tech Assistant. He assists managers and works with techs, customer shuttles, parts ordering, and inventory control.

He is learning that ordering inventory and parts for the shop and tracking what needs to be reordered daily takes a lot of effort. He assists the techs with repairs like brakes and similar work. Shane is a graduate of Archbishop Mitty High School and the University of St. Thomas in St. Paul, Minnesota (2025) with a major in Exercise Science.

Go 49ers, Warriors, Sharks, and Giants, and warmed up to the Vikings while in MN.....NO!!!!
