Meet the Tempe Team Behind Servo Garage Doors Tempe

We’re a small crew, and that’s on purpose. Every technician who shows up at your door in Tempe is someone Marcus Deller has worked beside, trained, and trusted with his name on the work order. No subcontractors, no rotating cast of strangers. Just a handful of people who know torsion springs, logic boards, and the particular ways Arizona heat punishes a garage door opener. Since 2015, this team has serviced more than 18,000 doors across the Valley, and every one of those jobs was priced in writing before the first tool came off the truck.

Our People

Marcus Deller, Owner and Lead Technician

Marcus founded Servo Garage Doors Tempe in 2015 after years of watching garage door companies quote one price over the phone and another after the work was done. He built the company around a rule that sounded radical then and still separates him from most of the market: the customer sees the failed part, held in the technician’s hand, before anyone quotes a replacement. Marcus still runs calls four days a week because he says a business owner who stops touching torsion springs starts making decisions that only look good on paper. His specialty is spring engineering, matching wire diameter and coil count to door weight so the spring lasts more than a couple of Arizona summers. When he’s not on a ladder, he’s reading warranty claims from manufacturers to see which parts are failing across the industry.

Rosa M., Senior Installer

Rosa has been with Servo since 2017 and handles most of the full-door installations in Tempe and north Chandler. She’s the one you want measuring rough openings, because she catches the things other installers miss: a header that’s sagging an eighth of an inch, a floor that slopes just enough to throw off the weather seal, a track that needs shimming before the sections go up. Rosa holds certifications on Clopay and Amarr installation and knows their product lines down to the hinge gauge. She grew up in Gilbert and still insists on driving back roads instead of the 60, which the rest of the crew gives her grief about every single week.

Devon T., Opener and Controls Specialist

Devon handles the electrical side of the trade: opener installation, logic board replacement, limit switch calibration, and the occasional mystery wiring job that other companies won’t touch. He came to Servo from commercial door work in 2019 and brought a habit of photographing every connection before and after, which fits the documentation standard we were already keeping. Devon is the tech who can tell you whether a LiftMaster DC motor is worth rebuilding or should be retired, and he’ll explain it in plain English with the part in his hand. Outside of work, he rebuilds old stereo receivers, which is either a clue to his patience or proof of it.

Lena K., Apprentice and Service Support

Lena joined the team in 2023 and splits her time between riding along with Marcus on service calls and managing parts inventory at the shop. She’s two years into her apprenticeship program and already handles safety cable replacements and roller swaps on her own, always under a senior tech’s review before the door gets cycled. Lena grew up in Tempe near Kiwanis Park and can tell you which 1970s-era houses in the neighborhood still have their original builders-grade doors, because she’s tracked them on more takeoffs than anyone else on the crew. She keeps a pocket notebook full of torque specs and part numbers, which the rest of us pretend not to rely on until we do.

One Standard, Every Job

The crew changes shifts, but the paperwork doesn’t. Every member of this team works under The Haven Standard, which is a written agreement, not a vibe. Clause 1 means the written price and written scope happen before any work starts, and that applies whether you’re getting a spring replaced in a Tempe townhome or a full door retrofit on a house near ASU. Clause 4 is the photo record: the failed part gets photographed, you see it, and the quote is built around what’s actually broken. When a job closes, you receive documentation of what was found and what was done. That’s the part Marcus says most companies skip because it’s easier to bill blind. We’ve been holding ourselves to this since 2015, and we intend to keep doing it because the photo record doesn’t lie, even on the rare day a tech might be tempted to. The standard is the same on every truck, every call, every time.
