Meet the Fontana Team Behind Servo Garage Doors Fontana
The crew that shows up at your door in Fontana isn’t a rotating cast of subcontractors. It’s the same four people who’ve been working Inland Empire garages long enough to know that a torsion spring on a Southridge home fails differently than one in a Northgate condo. They’re background-checked, uniformed, and they work under one rule: write the price before touching the door. Marcus Deller built the team that way when Servo Garage Doors Fontana opened under The Haven Standard in 2015, and the roster hasn’t churned since. When you call (951) 307-0747, one of these people answers.
Our People
Marcus Deller, Owner & Lead Technician
Marcus started Servo Garage Doors Fontana in 2015 after spending ten years watching garage door companies quote low over the phone and bill high in the driveway. He built the business on the opposite: a flat, written price and written scope before any work starts. That’s Clause 1 of The Haven Standard, and he’ll cite it by number while he’s measuring your spring. Marcus still runs service calls most days and still takes the after-hours phone. If your emergency call comes in at 2 a.m., the voice on the other end is likely his. He services all eight major brands, which means he’s the one untangling a Chamberlain logic board issue in the field, not reading a manual in your driveway. His one dry observation after eighteen thousand doors: “Every garage door tells you what’s wrong. Most people just don’t want to listen to it.”
Diego R., Senior Installer
Diego has been hanging doors in Fontana for over fourteen years, eight of them with Servo. He’s the guy who can install a new Clopay or Amarr door on a house in the Jurupa Hills and make it look like it was built with the place. His specialty is full door replacement and new construction installs, where the track has to be measured to the eighth of an inch or you’ll feel it every time the door closes. Diego carries certifications on LiftMaster and Genie opener systems and handles most of the opener installation work alongside Marcus. He’s the one who insists on documenting the finished install with photos before the truck moves, and he’s the first to point out that Clause 4 exists for a reason. Outside work, Diego restores old motorcycles and applies the same tolerance for imprecision to garage doors that he does to carburetors: zero.
Angela T., Service Coordinator
Angela is the voice you’ll hear when you call during business hours, and she’s the reason the schedule actually works. She’s been with Servo Garage Doors Fontana since 2018 and knows the Fontana map the way a dispatcher should: she can tell you that the drive from Citrus Heights to West End takes eleven minutes on a Tuesday morning. Angela handles the written estimates, the parts ordering, and the documentation packets that go out after every job. She’s the reason every customer leaves with a photo record and a written warranty in hand, not a vague promise. When you call with a broken spring and a family van stuck inside the garage, Angela’s the one who names the technician, texts the on-the-way update, and gets the truck moving in minutes. She doesn’t say “we’ll get back to you.” She says “Diego is leaving at 1:15.”
Marcus Jr., Apprentice Technician
Marcus Jr. is the newest member of the team, two years into his apprenticeship under the owner. He started hauling parts and watching, and he’s now running diagnostics on openers and trolley carriages with supervision. He’s the one photographing the failed part before any replacement gets quoted, which means he’s learning the trade from the evidence up, not from a sales script. Marcus Jr. grew up in Fontana and takes a particular satisfaction in fixing the doors of the same neighbors who watched him learn to drive. He’s not yet running solo on torsion spring replacements, but he’s in training, and The Haven Standard doesn’t rush that timeline.
One Standard, Every Job

The thing that holds these four people together isn’t a motto on a van. It’s a written standard with clauses that get cited on the job, not in a training binder. Clause 1 is the written price before work starts, every time, no exceptions. Clause 2 covers the documented photo record on every visit, so you see the failed part before anyone quotes a replacement. Clause 3 is the Free Second Opinion on any written estimate from another company; bring the paperwork, we’ll look at it. Clause 5 is the 365-Day Done Right Promise: if it’s not right, we make it right. Every technician in Fontana works the same way, so you get the same outcome whether Marcus is on the call or Diego is. That’s the standard, and it’s on the terms page, not a handshake.
