The Story Behind STG Design Build

STG Design Build was born in 2020 out of a problem I kept seeing over and over again. I had been working as a freelance architectural designer with multinational firms, and I watched homeowners and business owners struggle with the same frustrating issue: coordinating multiple consultants. Projects would drag on for months, mistakes would pile up, and when something went wrong, everyone pointed fingers at each other. It was exhausting for clients and honestly, it bothered me that there had to be a better way.

My background is in interior and architectural design, but I learned construction from the ground up. I took internships with major builders and worked across Egypt, New York, and California on everything from interior design to architecture to actual construction. That hands-on experience taught me that the best projects happen when design and build work together, not separately.

In 2020, I got my contractor's license and decided to do things differently. I wanted to create a firm that handled everything – A to Z – so clients wouldn't have to manage five different consultants who don't talk to each other. God really blessed me with incredible mentors and skilled workers along the way who believed in this vision.

The beginning was overwhelming, honestly. Our first clients were family and friends, then referrals started coming in, then business owners. There was one quarter that was so slow I actually considered finding a regular job. But right after that rough patch, everything changed. The work started flowing, and it hasn't stopped since.

Today, we have a team of 9 design professionals and over 20 construction specialists and subcontractors. We completed over 100 design projects in 2025 alone. We focus primarily on commercial and multifamily projects, though we still love helping with smaller renovations, additions, and ADUs.

What makes us unique is our integrated approach – we handle site visits, architectural design, structural engineering, MEP (mechanical, electrical, plumbing), permit processing with the city, and construction if needed. We're licensed, bonded, and insured for everything. We just signed a major B2B contract with Vita Spaces to serve the Altadena community, which feels like a full-circle moment.

I'm most proud of my team, family, and friends who kept this firm alive during the rough COVID times and helped us scale to where we are today. Looking ahead, our vision is to keep serving communities and homeowners, and within the next five years, we hope to start acquiring and developing land to build quality multifamily and commercial projects ourselves. We want to be the solution we wished existed when we started.

I'm sure it wasn't obstacle-free, but would you say the journey has been fairly smooth so far?

Smooth? Not even close! But I think that's true for any entrepreneur who's being honest.

The biggest challenge early on was cash flow and inconsistent work. When you're starting out, you don't have a steady pipeline. We'd have a great month, then nothing for weeks. There was one quarter – I mentioned this earlier – where it got so slow that I genuinely considered shutting down and finding a regular job. I had bills to pay, a team depending on me, and the phone just wasn't ringing. That was probably the lowest point. But looking back, that struggle taught me resilience and forced me to get better at business development and client relationships.

Wearing too many hats was another huge challenge. In the beginning, I was the architect, the engineer, the project manager, the salesperson, the accountant – everything. I'd be on a job site at 7 AM, then rushing home to finish drawings until midnight. It was exhausting, and honestly, unsustainable. Learning to delegate and build a team was hard because it meant trusting others with the quality and vision I had in my head.

The permitting process and city bureaucracy has been an ongoing battle. Every jurisdiction has different requirements, and navigating that while trying to keep projects on schedule is incredibly frustrating. We've had projects delayed months because of permit issues that were completely out of our control. Learning to build those timelines into our estimates and manage client expectations around government processes has been a steep learning curve.

COVID-19 hit right when we were getting momentum in 2020. Projects stopped. Clients got scared. Supply chains went crazy. We had to pivot quickly, figure out remote work, deal with skyrocketing material costs, and keep our team employed when revenue dropped. Honestly, I don't know how we survived that period except through faith, great people around me, and sheer determination not to give up.

Managing growth has been its own challenge. Going from just me to 9 designers and 20+ construction professionals meant learning systems, processes, quality control, and team management. I'm a designer and builder at heart – not an HR manager or operations expert. I've made mistakes in hiring, in project management, in communication. Every mistake taught me something, but they were expensive lessons sometimes.

Finding and keeping good people is always hard in this industry. Construction and design professionals are in high demand, and when you're a smaller firm competing with bigger companies, you have to work extra hard to create a culture people want to be part of.

But here's the thing: every struggle made us stronger. The slow times taught me to hustle. The cash flow problems taught me financial discipline. The growth pains taught me to build systems. The setbacks taught me resilience.

Would I want to go through it all again? Probably not. But am I grateful for the journey? Absolutely. Those struggles are what made STG Design Build what it is today – a company that understands our clients' pain points because we've been through our own.

Great, so let's talk business. Can you tell our readers more about what you do and what you think sets you apart from others?

What We Do: The Complete Solution

STG Design Build is a fully integrated design-build firm specializing in ASMEP services – that's Architectural, Structural, Mechanical, Electrical, and Plumbing engineering. But what that really means is simple: we're your single point of contact from concept to completion.

When a client comes to us, whether it's a business owner planning a commercial space or a homeowner dreaming of an ADU, they get everything under one roof. We handle the initial site visit and consultation, create all the architectural and engineering plans, navigate the city permit process, and if needed, manage the construction. We're licensed, bonded, and insured across all these disciplines, which is actually pretty rare in our industry.

What We Specialize In

Our sweet spot is commercial and multifamily projects – office buildings, retail spaces, apartment complexes, mixed-use developments. These projects are complex, with multiple systems that need to work together perfectly, and that's where our integrated approach really shines.

That said, we haven't forgotten our roots. We still take on residential projects – additions, renovations, ADUs (accessory dwelling units) – because those projects often mean the world to the families we're serving. There's something special about helping a family add space for an aging parent or create a home office that changes their daily life.

What Sets Us Apart: No More Finger-Pointing

Here's the problem we solve: In traditional construction, you hire an architect who designs something beautiful. Then you hire a structural engineer who says, "That won't work structurally." Then the MEP engineer says, "We can't fit the ductwork in that ceiling height." Then the contractor says, "This is going to cost twice what you thought." Everyone's working in silos, nobody's talking to each other, and when something goes wrong, everyone points fingers.

We eliminate that chaos.

Because we handle architecture, structural, mechanical, electrical, and plumbing in-house, our designs are coordinated from day one. The architect and the structural engineer are literally in the same meeting. The person designing the beautiful ceiling knows exactly what mechanical systems need to fit in it. There are no surprises, no finger-pointing, no "that's not my responsibility."

Our clients love this for three reasons:

• Time savings – Projects move faster when you're not coordinating five different consultants
• Cost predictability – Fewer surprises mean fewer change orders and budget overruns
• Peace of mind – One team, one vision, one point of accountability

What We're Known For

In our community, we've built a reputation for reliability and quality. We're the firm you call when you want it done right, even if it's complicated. We've become known for taking on challenging projects that other firms might shy away from – difficult sites, complex code requirements, tight timelines.

We're also known for our responsiveness. In an industry where contractors ghost you and consultants take weeks to return emails, we pride ourselves on being available and communicative. Our clients aren't left wondering what's happening with their project.

Recently, we signed a significant B2B partnership with Vita Spaces to serve the Altadena community, which has really elevated our visibility and validated our approach at a larger scale.

What We're Most Proud Of: Our Brand Values

Brand-wise, what I'm most proud of is that STG Design Build means integrity and competence. When people see our name on a project, they know:

• It's going to be done right – We don't cut corners. Ever. If there's a structural issue, we fix it properly. If code requires something, we do it, even if it costs us margin.
• We'll communicate honestly – If there's a problem, we tell you immediately and present solutions. No surprises at the end.
• We stand behind our work – Licensed, bonded, insured isn't just paperwork to us. It's a promise that we're professionals who take responsibility.
• We care about the outcome – Every project isn't just a job; it's someone's dream, their business, their home. We treat it that way.

I'm also incredibly proud that we're a team people want to work for. In an industry with high turnover, our designers and construction professionals stick with us because we've built a culture of respect, growth, and excellence. That stability translates directly into better outcomes for our clients.

But regardless of how we grow, our core mission stays the same: eliminate the chaos, deliver excellence, and make construction projects something people feel good about instead of dread.

If that resonates with you, we should talk.

What are your plans for the future?

The big shift for us is moving from service provider to developer. Within the next five years, we plan to start acquiring land and developing our own multifamily and commercial projects. Instead of just designing and building for clients, we want to create quality developments that serve our communities directly.

We're also focused on strategic growth – expanding our B2B partnerships like the one we have with Vita Spaces, and scaling our capacity to take on larger, more complex projects without losing the quality and personal attention that built our reputation.

On the team side, we're investing in our people. We want to create clear career paths for our designers and construction professionals, building a company where talented people can grow long-term.

And honestly? I'm excited to prove that you can scale a construction business without sacrificing integrity. Too many firms get bigger and lose what made them good. We're determined to grow while keeping the values that got us here – reliability, quality, and treating every project like it matters.

The Altadena community partnership is just the beginning. We're ready for what's next.
