As founder and CEO of The Lachlan Group, Collier Erwin leads a full-service real estate and property management firm based in Battle Ground, Washington. A native Washingtonian with advanced education in Anthropology and Criminology, Collier brings a distinctive, analytical perspective to the real estate industry. After observing a lack of accountability and core values in previous workplaces, he set out to build a company grounded in a higher benchmark for service and leadership—what is now known as The Lachlan Standard.
The Lachlan Standard is rooted in the principle of “running into the storm,” a no-nonsense, team-oriented approach that prioritizes clarity, resilience, and unwavering commitment to clients. This philosophy guides every relationship, decision, and outcome across the organization.
Collier is a recognized leader in the Pacific Northwest real estate market, delivering integrated solutions across residential sales, commercial real estate investment, property management, and new construction development. He is particularly known for his strategic insight into local market trends, including the emerging build-to-rent (BTR) sector. His client-first mindset focuses on building long-term wealth through disciplined investment strategies and meticulous property oversight.
Dedicated to transparency, ethical business practices, and exceptional execution, Collier holds every project to The Lachlan Standard—defined by precision, proactive problem-solving, and consistent results. His attention to detail and commitment to excellence ensure successful project delivery, elevated property performance, and lasting client satisfaction. Driven by a deep passion for real estate, Collier continues to innovate, protect value, and maximize returns for investors and homeowners alike.
