About Me

A native Houstonian who calls San Antonio home, Mary Grilliette loves Texas and thinks San Antonio is the best city to live!


Mary graduated from the University of Texas at Austin, began a career in fashion, designed and owned a line of tennis clothes, Mary O’s Tennis Fashions, became a dedicated mother, homemaker, “professional volunteer” and now a successful realtor. She has been a PTA President, a Board Member of Ronald McDonald House, Alamo City Republican Women and Seton Home.


Mary and her husband Alan have two children, Burke and Michelle. Mary believes her job as a stay at home mother, homemaker and volunteer was a true career that prepared her for her real estate career.


Mary loves tennis. In high school, she won the Texas State Tennis Doubles Championship for Stratford High School in Houston. Her dad played professional baseball, wanted his daughter to play a sport and Mary is grateful he taught her the life-long sport of tennis. 

Staying in shape physically is important but taking care of your soul is the most important. Mary’s Catholic faith is what she relies on to give her strength and peace as she goes through the good time and bad times in life.


There have been incredible women that have infl uenced Mary. Her mother and grandmother were the epitome of wonderful mothers, homemakers & hostesses. Her great-aunt taught Mary to love and appreciate our country, the arts and the beauty of nature. Her daughter, Michelle, is a true inspiration for living a positive life! Because of the infl uences of these wonderful people, Mary loves to entertain, cook, volunteer and enjoy life! “This is not a practice life, live it to the fullest.”
