Meet your Denver Realtor 

Grant and his team are passionate about creating a stress-free home buying or selling experience by cultivating a meaningful relationship with each and every one of our clients. Yes - we are a team of Denver real estate agents - but we are also residents, parents, and neighbors, just like you.

Grant has a diverse business background, combined with expert negotiation skills. His extensive knowledge of the real estate market comes from being an experienced Denver real estate agent, a long-time Denver resident, and local enthusiast. This helps him advocate for his clients through every step of the buying and selling process.

To Grant, relationships are everything. He understands the gravity that home carries and the value that it holds for the people who live there.  As such, the Denver real estate agents at Spaces now stand as a fanatically client-focused company that holds relationships above revenue and client service over compromises.

Great People Don't Work Alone

Grant Muller


Grant is contagiously high-energy, ridiculously responsive and obsessed with his clients' success. As an expression of his desire to help anyone and everyone find comfort in "home," no matter where it is, Grant is heavily involved in organizations dedicated to Denver's homeless. He is a Board Member and Chair of the Development Committee at Urban Peak, a local non-profit that provides shelter and resources to homeless youth.  Grant also sits on the board of the Renaissance Housing Development Corporation, which builds housing for homeless individuals who would otherwise be living on the streets.  

Personally, this family man and animal lover has happy places at every turn and corner. Be it riding his horse, enjoying a sushi and ice cream date night with his fiancé Adrian, skiing the slopes with friends, or cuddling up with his favorite canine companion Winston and feline friend Nala Lupe, Grant Muller is never far from home.

Brooke Cartwright


When it comes to buying, selling, living and loving real estate, our girl Brooke airs on the side of awesome. Growing up in Arizona and graduating from U of A with a business degree was the start of this wanderlusting agent’s journey into the industry—with a stint as a custom kitchen designer in between. She’s traveled all over and lived in four cities, including Maui, where she met her now-husband, a commercial pilot from Denver. Colorado already ranked high on her like-to-live list, so one golden retriever, one move, one marriage, and one daughter later, this Mile-High mama now knows all the Denver ‘hoods, nooks and crannies by heart with lots of happy homeowners to prove it.

Find out why our clients love us.
