Our story

Dealer-Quality Work. Independent Prices.

Precision Auto Works opened in 2009 out of a two-bay space on Westheimer. Marcus Rodriguez had spent a decade as lead technician at a BMW dealership — using factory diagnostics, pulling manufacturer scan data, doing it right. He knew the gap was not in knowledge or equipment; it was in the markup. Dealership service customers were paying 40% more for the same work. Marcus opened with one lift, one promise: show every customer what we find before we fix it, and charge them honestly.

Montrose started talking. Then the Heights. Within two years the shop had expanded to six bays and Marcus had hired David — a drivetrain specialist who had seen more transmission failures than most techs see in a career — and Angela, whose combination of technical literacy and plain-spoken communication style turned first-time customers into regulars. In 2018, Ray Nguyen joined from a Honda dealership, bringing oscilloscope-level electrical diagnosis and EPA 609 certification for AC work at exactly the moment Houston summers started getting longer and harder on refrigerant systems.

Fifteen years on, the shop services over 5,000 vehicles a year and holds a 4.9-star Google rating across 600+ reviews. The standard has not moved: photograph the inspection, send the report, write the estimate, wait for approval. Never pick up a wrench before the customer says go. The 3-year / 36,000-mile warranty is not a marketing line — it is the consequence of doing the job right every single time.

01 / What we stand for

How we work

You See What We See

Every inspection is documented with photos and video and sent to your phone before we recommend anything. Borescope, brake-pad calipers, battery load tester — we show you the instrument reading, not a technician's summary.

Written Estimate, No Surprises

You receive a line-item written estimate before a single bolt is turned. The number on the estimate is the number on the invoice. No labor-clock overruns, no parts markups added after the fact.

3-Year Warranty, No Fine Print

Every repair leaves with a 3-year / 36,000-mile warranty on parts and labor. If it fails under normal conditions in that window, we fix it free. We put it in writing because we mean it.

Diagnose Before You Prescribe

We do not guess and we do not sell parts to see if they fix it. Every diagnosis starts with scan data and a hands-on inspection. You get the real cause, not the probable one.

Earned Repeat Business

About 70% of our work comes from repeat customers and their referrals. We have never run a coupon that required pressure tactics to redeem. Honest work brings people back — that is the only growth model we trust.

02 / The crew behind every repair

Master techs, not parts changers

MR

Marcus Rodriguez

Owner & Master Technician

ASE Master Certified (L1), TX Inspector, 16 years experience

Marcus grew up rebuilding engines in his father's Montrose garage. After earning his ASE Master Certification and spending a decade as lead tech at a BMW dealership, he opened Precision Auto Works on Westheimer in 2009 to prove that independent shops can match dealer diagnostics at half the price. He signs every repair order that leaves the shop.

DT

David Thompson

Lead Technician — Drivetrain

ASE Certified: Engine, Transmission & Brake Systems, 15 years

David joined Precision on opening day and has been Marcus's right hand for fifteen years. He specializes in drivetrain diagnostics and complex engine work — the hard calls that stump other shops. He has pulled more than a few post-Hurricane flood motors and knows exactly what salt water does to a transmission solenoid pack.

AF

Angela Foster

Service Advisor

ASE Service Consultant Certified, bilingual (English/Spanish)

Angela is the first voice you hear when you call Precision. She translates DTC codes and torque specs into plain language, walks every customer through the photo inspection report, and has never once let a job leave the shop without a written, approved estimate. Fluent in English and Spanish — a daily advantage in Houston.

RN

Ray Nguyen

Technician — Electrical & AC Specialist

ASE Certified: Electrical Systems, EPA 609 Certified, 8 years

Ray spent eight years at a Honda dealership before joining Precision in 2018 for the diagnostic challenge. He specializes in electrical diagnosis, AC system repair, and hybrid vehicle service. In a city where summer cabin temperatures hit 130°F, Ray's borescope and AC manifold gauges are the most-used tools in the bay.
