Lifelong Mover (Until Now) | Tucson Realtor | Historic & Unique Home Enthusiast
I’ve been a licensed Realtor® since 2018, but my real estate journey started long before that, mostly by packing and unpacking boxes! I’ve lived in ten states and eighteen cities, so I know firsthand how exciting (and stressful) moving can be. Whether you’re buying or selling, I get it, because I’ve probably been in your shoes more times than I can count.
I love helping people find a hidden gem in an established neighborhood—one they can tweak, renovate, and fall in love with. And let’s be honest, Tucson is full of “why haven’t I seen this before?” kind of homes, and I love helping people discover them! Unique and historic homes are my absolute favorite (next to Edy’s Caramel Pretzel Path ice cream, of course).
My Background (before becoming a Tucson Realtor)
Before diving into real estate, I spent six years managing MBA programs and somewhere along the way, I figured an MBA from Eller would pair nicely with my undergrad degree in English—because what’s better than mixing business strategy with a love of words? On the personal side, I have two daughters who keep life interesting. My oldest graduated from the University of Arizona with a degree in physiology, proving at least one of us understands science. My youngest turned her passion for pastry and baking arts into a job at Disney World, where she makes magical treats while I resist the urge to ask for free samples.
So, back onto Tucson real estate, if you need help buying, selling, or just want to swap moving horror stories, we’re your team! Also, if you love unique and historic homes like we do, let’s love some together.

Fifth-generation Tucsonan | Tucson Realtor | Outdoor Enthusiast
With deep roots in Tucson, I bring a fifth-generation local’s perspective to real estate in Tucson’s historic neighborhoods. I love helping clients navigate the market, whether they’re looking for a unique home with character or selling a one-of-a-kind property.
Outside of real estate, you’ll find me hiking Tucson’s scenic trails, exploring native plant life, and advocating for sustainable living. I believe in preserving both our natural spaces and our city’s historic architecture—because the beauty of Tucson isn’t just in its landscapes, but in its homes and neighborhoods too.
So, let’s connect and find your perfect piece of Tucson!

Musician | Tucson Realtor | Pop Culture Enthusiast
I’m thrilled to be part of The Agent CoOp, bringing enthusiasm and expertise to buyers and sellers in Tucson’s unique and historic neighborhoods. I have a special appreciation for the character and charm of Tucson’s older homes and love helping clients find the perfect space.
When I’m not guiding clients through Tucson real estate, I’m likely in my music studio or at a local venue. I also have two incredible teenagers, one of whom is heading to Flagstaff to pursue a nursing career.
So, let’s meet, share stories, and talk about how I can help you buy or sell a home in Tucson!

Meet the Founders
Kimberly, a Tucson native, and Matthew, who moved here in 1974, share a deep appreciation of the Sonoran Desert, which they will forever call home. With a love of the landscape, the diverse cultural heritage and architectural beauty, they put their passion to work as successful Realtors® and dedicated participants in the community, helping those in need.
What began simply as a decision to go on their own, quickly attracted other Realtors® who appreciated their professionalism, knowledge, strong work ethic and charitable outreach. Listening to their clients’ and agents’ needs soon produced the model for their real estate success…”Treat agents as family, and give them all the resources they need to serve their clients best.”
From their first days in real estate, Kim and Matt Clifton’s passion for the industry always motivated them to seek every resource available to make Tierra Antigua Realty a state-of-the-art organization for knowledge and empowerment. As a result, Tierra Antigua Realty has an unsurpassed reputation and has grown to the largest, locally-owned real estate brokerage in Southern Arizona.
