Meet the Lantana Team Behind Sightline Windows & Doors Lantana
The crew that shows up at your door in Lantana isn’t a rotating dispatch pool. These are the same people who measured the opening, specified the product, and will stand behind the install. What ties them together is the Haven Standard, which we’ve applied to every one of the 18,000+ windows and doors we’ve put in since 2012. In Lantana, that means background-checked, uniformed technicians with license numbers on the page, a written price before any work starts, and a documented photo record when we’re done.
Our People
Marcus T., Lead Technician
Marcus has been with Sightline since 2017, which means he’s handled roughly 2,400 openings across Palm Beach County. His specialty is impact-rated installs on older Lantana homes built before the 2002 code changes, where the rough opening is never quite square and the stucco reveals surprises once you pull the old frame. He’s certified in PGT and CGI impact systems, and he keeps a laminated cheat sheet of Lantana’s wind-borne debris zone requirements in his truck because the city inspector asks for specific documentation. Off the clock, Marcus restores vintage motorcycles and brings that same tolerance-for-no-tolerance to every frame he squares.
Dana R., Senior Installer
Dana came to us from commercial glazing in 2019 and immediately raised our standard for custom and geometric window work. She’s the person we send when a customer in Hypoluxo Island or the Moorings wants a trapezoid or radius window that actually seals against a 150-mph wind load. Dana is certified in CWS and ES Windows fabrication, and she’s trained two apprentices in the math of compound miter cuts on impact glass. Her human detail: she names her tape measures, and “Lucky” is on its fourth replacement because she refuses to switch brands after a decade of reliable reads.
Carlos V., Service Coordinator
Carlos runs the schedule and the phone, which at Sightline means he also reviews every measured survey before it becomes a written quote. He’s been with us since 2020, and he’s the reason our Lantana customers get a callback within the hour instead of a voicemail black hole. Carlos holds manufacturer certifications from ECO Window Systems and Therma-Tru, so when he’s on the phone discussing a patio door swing direction or a garage door track configuration, he’s speaking from product knowledge, not a script. He grew up in Lake Worth and still lives there, which means he knows which Lantana neighborhoods flood first in a summer storm and factors that into our flashing recommendations.
Jin K., Apprentice Installer
Jin joined us in 2023 after completing a construction technology program at Palm Beach State. She’s in her second year of the Sightline apprenticeship, which means she’s logged roughly 400 installs under direct supervision and is now cleared to handle standard vinyl replacement windows and sliding patio doors solo. Jin is working toward her Mr-Glass and ViewLux certifications, and she’s already developed a reputation for spotting water intrusion patterns that others miss, probably from the year she spent documenting mold remediation cases before switching to windows. She commutes from Boynton Beach and is usually the first one on site because she beats the bridge traffic.
One Standard, Every Job

The Haven Standard governs every Sightline location, but in Lantana it’s executed by this specific crew. Have it in writing: the measured survey you keep and the written price that cannot change. Arrive on schedule: the technician who shows up is the one on your paperwork. Verified crews: background-checked, uniformed, license number provided before arrival. Evidence on every job: the documented photo record you receive at completion. No surprises: the 365-Day Done Right Promise, written into every contract, not offered as a courtesy.
Across our network, the same standard applies. But in Lantana, you’re not getting a network. You’re getting Marcus, Dana, Carlos, and Jin, with Sonia Raman reviewing every written quote before it leaves the office. That’s the difference between a brand promise and a brand practice.
Call (561) 461-2062 to schedule your free estimate. You’ll speak to a live person, 24/7, and the price we write is the price you pay.
