Tierra Antigua is locally grown! September of 2001 Matt & Kim Clifton founded Tierra Antigua Realty. “Tierra Antigua” means “ancient earth” in Spanish. I am proud to be at the largest, locally-owned real estate brokerage in Southern Arizona. I've been with Tierra Antigua from the first location with less than 100 agents. I've seen the growth and dedication to our community over the years. That is why I am proud to be part of such an amazing company.
