Meet the Founders

Kim and Matt Square

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.
