ABOUT ME
My name is David Semenov, and I am the founder and owner of Peakstone LLC.
I grew up in a family of builders. My father has more than 50 years of experience in construction, and from an early age I learned from him the importance of craftsmanship, discipline, and responsibility for the final result. Together with my brothers, we spent our childhood learning the trade hands-on, developing skills over time and gaining experience that can’t be taught from books.
Today, we work as a team. My brothers and my father are involved in the growth of the company, and each of us understands that construction is not just a job — it’s trust. Our clients invite us into their homes, and we treat that responsibility with seriousness and respect.
We are a large family, which you can see in the photo. But what truly matters are the values we share: respect for personal space, attention to detail, and a thoughtful, careful approach to every project.
We understand that a home is more than just a structure. It’s where people live, grow, and create memories. That’s why we work calmly, precisely, and with full awareness that the results of our work remain with our clients for years to come.
OUR TEAM
Our team is fully licensed in Washington State and brings years of hands-on experience in residential and commercial construction.
Each member of our crew is trained, qualified, and committed to working safely, responsibly, and to code. We combine technical knowledge with practical experience to deliver consistent, high-quality results on every project.
We believe strong results come from a strong team — professionals who take pride in their work and understand the responsibility that comes with working in people’s homes.
OUR APPROACH
We focus on clear planning, honest communication, and doing the job right the first time. Every project is approached with care, precision, and respect for the space we work in.
WHAT YOU CAN EXPECT
Reliable timelines, transparent pricing, and quality craftsmanship you can trust. No shortcuts, no surprises — just solid work done responsibly.
