Meet the President and Principal Broker of Horizon Properties, Inc.

Originally from Bolivia, South America, Maria Miller has lived in the U.S. since age 10. After moving to Hawaii in 1976, Maria obtained her real estate license there in 1978. With almost 40 years in real estate, Maria has accumulated a vast amount of knowledge and experience. 

Maria is the President and Principal Broker of Horizon Properties, Inc. and since 2007 the Horizon team has had the pleasure of assisting, both local and off-island, investors to purchase a couple of hundred investment properties here in Guam. However, Maria’s passion is helping first time home-buyers realize they can own a home they never thought they could afford. Maria has also assisted hundreds of Veterans to buy homes not only with NO DOWN but also with little or no $$$ out of pocket for closing costs.  

With Maria’s passion to serve others and hard work over the past 40 years, it has brought her to the place where she now serves as Guam’s current President of the Guam Association of Realtors. In addition, she also contributes time and resources to the local community through various charitable organizations. 

When she is not busy working for her clients, Maria enjoys visiting with her four grandchildren in Ohio, volunteering in the music and drama department at her church, and spending quality time with friends here on Guam and abroad.
