Meet the Founders

Matthew and Kimberly Clifton were top producing REALTORS® in Southern Arizona for many years. They saw an opportunity to reinvent the real estate brokerage model in a way that would put the needs of agents, clients, and the community first. In September of 2001, they founded Tierra Antigua Realty. “Tierra Antigua” means “ancient earth” in Spanish.

Together, Matt and Kim have orchestrated a rise to excellence that has seen their brokerage currently employ over 900 agents, capture the second largest market share in Southern Arizona, and open three Tucson offices, one Green Valley/Sahuarita location as well as one Sierra Vista office.

With Kim at the helm as designated broker, Tierra Antigua Realty has achieved acclaim as a top 60 regional employer, a consistent community service award winner, and as one of the most recognizable brands in Southern Arizona.

Kim’s passion for service to her fellow professionals is evident. She has served as chair of the Arizona Real Estate Advisory Board, multiple terms as president of the Tucson Association of REALTORS® Multiple Listing Service, multiple terms on the Tucson Association of REALTORS® Board of Directors, and on the Arizona Association of REALTORS® Board of Directors.

Matt and Kim possess magnetic personalities, razor sharp business acumen, and have a history of success across the real estate industry. Their leadership style is to personally engage those they serve with an attitude of warmth, caring, and a willingness to listen. They are personally dedicated to raising the bar in real estate every day.
