I help Seattle and Eastside landowners, brokers, and investors make confident decisions about infill development, without surprises, retrades, or guesswork.
If you want a clear, builder-led understanding of what a property or opportunity can actually support, you’re in the right place.

Who This Is For:
 → You own land in Seattle or the Eastside and want a clear, honest view of its redevelopment potential
 → You’re a broker who values certainty, clean execution, and protecting client relationships
 → You’re an investor looking for disciplined, construction-backed underwriting

How I Help:
I guide projects from feasibility through delivery using a vertically integrated model designed to reduce risk and misalignment.

We manage everything in-house:
Feasibility → Design → Permitting → Construction → Sales

Fewer handoffs. Fewer delays. Clearer outcomes.

Why That Matters:
Infill projects fail when assumptions break down between zoning, design, and construction.
We focus on aligning those decisions early, so projects pencil realistically and deliver as expected.

A Bit of Context:
I grew up building homes, earned a degree in Construction Management, and spent six years helping deliver large-scale development projects across the region. That experience shapes how we operate today.

What I Believe:
Landowners deserve straight answers.
Brokers deserve certainty and follow-through.
Investors deserve disciplined, full-cycle underwriting.

Good housing comes from clarity and accountability. Not shortcuts.

Let’s Talk:
If you want a clear read on what your property or opportunity can support, feel free to reach out. Happy to help.

Concrete pumpers are having a moment at my house.

Lately, my son and I have been reading a construction site book before bed. Every page features a different machine, excavators, loaders, dump trucks… and of course, the concrete pumper.

Now when we’re driving through Seattle, he sees them before I do.

“Dad! Concrete truck!”
“Dad! Big boom truck!”

This week, that “big boom truck” showed up at our Queen Anne Townhomes project.

10 infill townhomes.
Tight urban site.
Foundations going in.
Concrete pumping all morning.

There’s something grounding about watching concrete flow into forms. It’s early work. Unseen work. But it sets the trajectory for everything that follows.

My dad passed industry knowledge down to me the same way, not through grand speeches, but by working in the field with our own hands. Walking sites. Studying details. Learning how things actually get built. That exposure shaped how I see cities, housing, hard work, and responsibility.

Now I get to watch my son light up at the same trucks.
That part means more than any milestone photo.

At Olsen Anderson, we talk about shaping neighborhoods thoughtfully. But it starts here, with a solid plan, strong trade partners, disciplined execution, and people who care about doing it right.

And apparently, with a concrete pumper that steals the show.

Every once in a while, you get a note that reminds you why you do this.
A recent homeowner shared this with us after closing:

“I had nothing but terrible experiences with my first home purchase… It has been refreshing and honestly faith restoring to work with a company who views their product not just as wood and shingles, but as someone’s home. My family and I cannot thank you enough.”

In an industry where speed and scale often take priority, it’s easy to lose sight of what actually matters. A home is where life happens, where families grow, routines take shape, and connection to a neighborhood begins.

We think about that every day at Olsen Anderson. The details, the experience, the way a home fits into the fabric of a neighborhood, it all matters. Grateful for our team who shows up with that mindset, and for homeowners like Jeff who trust us with something this meaningful.

Welcome home.

Behind the Build: Framing is underway at Capitol Hill Townhomes.
Lumber just hit the site and Building A is going vertical. A big milestone for the team.

Behind the scenes, this project has been all about thoughtful execution. What could have been a massive export/import site, we’ve been able to balance through a phased foundation approach, reducing haul-off, cost, and disruption to the neighborhood.

Paired with well-draining soils, it’s allowed us to keep work moving steadily through the winter and wet season without interruption. A lot of planning goes into making construction look simple. Grateful for a team that continues to execute at a high level. More to come as this one takes shape.

When people think about development, they often think about buildings.

But what we’re really shaping are the places where everyday life unfolds.

Morning walks to coffee.
Neighbors stopping to talk on the sidewalk.
Sunsets over the Sound.

That’s why we’re excited to release Sundown at Sunset Hill, a collection of three homes in one of Ballard’s most loved neighborhoods.

Sunset Hill has a rhythm that’s hard to replicate anywhere else in Seattle. Quiet streets, puget sound views, and a strong sense of community, all just minutes from the energy of Ballard.

Projects like this are neighborhood in scale, but meaningful in impact.

Three thoughtfully designed homes that fit naturally into the neighborhood and create space for the next chapter of life to happen there.

If you’re curious to learn more about the homes or the neighborhood, you can explore the community in the comments below.

And if you’re a landowner thinking about what the future of your property could look like, I’m always happy to start a conversation.

Last week I had the chance to attend Forterra NW’s Spring Fundraiser and it was one of those evenings that sticks with you.

A room full of people who care deeply about land, community, and the long-term future of the places we call home. And even better, they met the board’s match and raised funds for a good cause.

What stood out most wasn’t just the fundraising success, but the shared belief that the places around us: forests, farms, rivers, and neighborhoods, don’t take care of themselves. It takes intention, stewardship, and people willing to step up.

That idea resonates deeply with how we think about housing and development. The built environment and the natural environment aren’t separate conversations, they shape each other.

Grateful to support Forterra’s work and be part of a community that’s thinking long-term about Washington’s future.

Flat sites are a gift in urban development.

Less time fighting the ground means more time building homes.

No temporary shoring.
No permanent shoring.
No excavation easements with neighbors.
No complex stepped excavation.

Just demo → foundations → vertical construction.

That’s exactly what’s happening on this 4-home infill site in Ballard, where foundations are going in now.

The last time we delivered this plan, the team completed it in 7 months from foundations to finish. We’re aiming to beat that timeline this round.

Small urban projects like this are where disciplined execution matters.

Four more homes taking shape in a neighborhood we love.

Behind the Build: Progress at our 64th St Townhomes is moving steadily forward.

Foundations are in and backfilled, and we’re now installing site utilities, setting the groundwork for everything that follows. This phase isn’t the most visible, but it’s one of the most important. Getting infrastructure right early ensures the homes perform as intended and the community functions seamlessly over time. It’s a good example of the kind of work that often goes unnoticed, but makes all the difference. More to come as this one continues to take shape.

Behind the Build: Aerial view at our Queen Anne Townhomes, foundations are now roughly 50% complete on this 10-home community.

This site comes with its challenges, including a steep slope that the team has been carefully managing from the start. But it’s also presented an opportunity. With strong infiltrating soils, we were able to execute value engineering to eliminate the originally designed stormwater pump system and instead infiltrate onsite. That means less long-term maintenance, fewer failure points, and a simpler, more resilient solution. At the end of the day, it’s always better to let water flow downhill than rely on pumping it back up. Thoughtful decisions like this don’t always show up in the final product, but they make a lasting difference in how these homes perform over time.
