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 closed 649 residential transactions totaling more than $353 million in recorded sales volume across Colorado. 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.
Homeowners preparing to sell
Pricing, preparation, positioning, marketing, showing strategy, offer analysis, negotiation, and closing coordination.
Clients buying and selling together

We had a good idea of what we wanted in a home when we first met with Steve, but he helped us refine that list and found a wonderful home for us that hit everything on our checklist, was in our ideal neighborhood and was a perfect fit for our budget. He worked with us on a Sunday night to determine our offer and get it in quickly, which was a big factor in us beating a competitive bid that came in the next day. During the contract/closing process, Steve was very helpful and responsive and did a great job of navigating the few contractual hiccups that came up along the way. As a first-time homebuyer, it was comforting that I knew I could trust him to get the job done correctly and on time.
Steve also referred us to a mortgage broker and an interior decorator, both of whom did a wonderful job for us. His deep connections in the Castle Rock business community and willingness to help out make him a valuable resource far beyond buying or selling a home. Highly recommended!
