Meet the Long Beach Team Behind Rowan Construction Group Long Beach
Every crew that walks through your door in Long Beach answers to the same standard. Background-checked, uniformed, and trained under The Haven Standard before they ever touch a project. What ties this group together isn’t a slogan. It’s the discipline of written prices, signed change orders, and photo records on every visit. We’ve been building in Long Beach since 2007, and these are the people who show up.
Our People
Grant Rowan, Owner
I’m the one who answers when something goes off-plan. Started this operation in 2007 after watching too many homeowners get a verbal “ballpark” that doubled by final invoice. I built Rowan Construction Group on Clause 1 of The Haven Standard: a written price before any work starts, period. I’ve personally reviewed over 4,000 project folders, and I still spot-check photo records from jobs across all seven trades. When I’m not on-site, I’m usually at the Long Beach warehouse sorting material samples from our 51-plus vetted brands, making sure the numbers in our quotes match what we can actually source. I keep a 1948 Craftsman level on my desk that my grandfather used in San Pedro shipyards. It still reads true.
Marcus T., Lead Technician - Kitchen & Bath
Marcus has been running full-gut kitchen and bath remodels for fourteen years, the last six with us in Long Beach. He’s certified in wet-area waterproofing through the Tile Council of North America, which matters more than most homeowners realize until they see what a failed shower pan costs to rip out. Marcus is the one who taught our apprentices to photograph the substrate condition before laying any backer board, not after. On weekends he restores vintage motorcycles in a garage near Bixby Knolls. He brings the same patience to both jobs.
Diana R., Senior Installer - Roofing & Exterior
Diana started as a roofing laborer in 2012 and worked her way to senior installer handling GAF and Owens Corning systems across Los Angeles County before joining our Long Beach crew in 2019. She can spot a double-layer shingle roof from the curb and knows exactly how the coastal salt air off the Port of Long Beach accelerates fastener corrosion on exposed flashing. Diana holds manufacturer certifications from both GAF and Owens Corning, which means our workmanship warranties carry their full backing. She keeps a tide chart bookmarked on her phone. Says it helps her predict which Monday mornings will start with emergency leak calls after weekend storms.
James K., Service Coordinator
James is the live voice you get when you call (424) 567-7009 at 11 PM with water coming through the ceiling. He’s been with us since 2018, scheduling across all seven trades while tracking permit status with Long Beach Development Services and coordinating inspections so crews don’t sit idle. James maintains the photo record system, tagging every image to the project folder before the truck leaves your driveway. He grew up in North Long Beach, knows which streets flood first in a hard rain, and routes crews accordingly. He also makes the best coffee in the office, which the field crews will confirm if you ask.
Elena V., Apprentice - Windows, Doors & Finish Carpentry
Elena joined us in 2022 after completing the carpentry program at Long Beach City College. She’s logged over 800 hours on window and door installations, working up from helper to rough-in lead on smaller jobs. Elena specializes in measuring existing openings for replacement units, a step where a quarter-inch error turns into a full-day delay. She’s currently pursuing her CSLB journeyman certification and shadows Marcus on kitchen finish work twice a month. Her first language is Spanish, which has helped us communicate directly with homeowners who prefer it. She carries a notebook with hand-drawn diagrams of every tricky installation she’s seen so far.
One Standard, Every Job

The Haven Standard travels with us, not the other way around. Every Rowan Construction Group crew in Long Beach operates under the same clauses that govern our network across California. Clause 1 means your written quote arrives before anyone picks up a hammer. Clause 2 means no change order moves forward without your signature, which is how we’ve kept projects within a few percent of the original number across 4,000-plus jobs. The 365-Day Done Right Promise is printed on every contract, backed by terms you can read, not an asterisk you can’t.
Our background-check and uniform policy applies to every person listed here, plus the specialists we call in for electrical, plumbing, or structural work. The photo record James tags? You get a copy. The written warranty? Included, not optional. When we say one standard, we mean the same documentation, the same process discipline, whether we’re replacing a fence in Belmont Heights or building a full ADU in the Zaferia District.
