Real estate expertise, built as a family business.
The Thayer Group is a family-owned Colorado real estate team based in Castle Rock and affiliated with Keller Williams Action Realty. Since 2008, we have represented buyers and sellers across Castle Rock, Douglas County, the Denver Metro area, and communities throughout the Front Range.
From our family to yours.
Real estate decisions are personal. Our job is to make the process clearer, more strategic, and better managed from the first conversation through closing.
Advice grounded in the market
We use local transaction experience, comparable sales, current competition, market data, and property-level analysis to help clients make decisions with context rather than guesswork.
A team with complementary strengths
Our principals bring different areas of expertise across brokerage leadership, negotiation, market statistics, transaction management, industry policy, and client representation.
Hands-on representation
We remain directly involved in strategy, communication, negotiation, and execution. Clients are not passed through a large production line or left wondering who is responsible for the next step.
Meet Steve, Susan, and Cooper Thayer, the three principals behind The Thayer Group and the expertise our clients rely on every day.

Depth that extends beyond a transaction count.
Experience is most useful when it improves judgment: how to price, when to push, when to pause, how to evaluate risk, and how to keep a complicated transaction moving.
Since 2008, The Thayer Group has completed more than 780 residential transaction sides representing more than $412 million in recorded closed sales volume across Colorado. Our public transaction record currently includes 726 transaction sides verified against MLS records. Our work spans first-time buyers, growing households, move-up clients, luxury properties, new construction, investment real estate, relocations, divorce-related sales, estates and inheritance, and sellers navigating complex timing or property conditions.
We are based in Castle Rock and affiliated with Keller Williams Action Realty. Our primary footprint includes Castle Rock, The Meadows, Douglas County, Parker, Highlands Ranch, Castle Pines, Lone Tree, Larkspur, the Denver Metro area, and Colorado Springs, with completed transactions extending across 36+ Colorado communities.
The breadth of that transaction history gives our team perspective across different market conditions, price points, property types, and negotiation environments. Clients benefit from that experience at the moments where judgment and execution matter most.
Real estate expertise for different stages of life and ownership.
Our practice is intentionally broad, with dedicated experience in several transaction types that require more specialized guidance.
First-time and experienced homebuyers
Education, property analysis, offer strategy, due diligence, and transaction management from initial planning through closing.

Clients buying and selling together
Coordinated timing, financing considerations, contingency strategy, and transaction planning when two moves need to work together.

Boots-on-the-ground support for clients managing a Colorado transaction from another state, including property access, vendors, inspections, and logistics.

Experience with new construction, investments, divorce-related real estate, estates and inheritance, and other transactions with added financial or logistical complexity.
