About

Real Estate has been my life for over 40 years. My husband and I moved to South Texas in 1972 when he had an opportunity to open his own business. We both had been raised in the Dallas/Ft. Worth area. After high school, I attended college and graduated with a degree in Education. I have been a high school counselor and I have taught business and social studies at the high school level. In 1980, I changed careers and began life as a Real Estate Agent/Broker. My son, Jasen, after college, joined me in the Real Estate business. In 1993, we opened the doors of Star Properties Real Estate in the Greater McAllen area. I have been awarded many Top-Performing sales awards during the years, including the 'Top Selling Agent' for the year among all agents in the McAllen area. I love helping people, whether it is a person's first home or for a family that has owned many homes. My goal is to make the home buying process a great experience. I work hard to have satisfied customers.

I love where I live. South Texas is my style. The warm climate and friendly people and the history of the area is like no where else.
My family is everything. My seven grandchildren are the light of my life. We talk weekly and grandma loves dispensing advice.
I am known as the What a Burger grandma. I keep 'What a Burger' gift certificates available to 'bribe' grandchildren to come see me regularly.

About

Diana’s work ethic was shaped early, hustling since 16 and bringing over 20 years of experience to RE/MAX. Raised in Corpus Christi, she was inspired by her father, a respected contractor, learning that real estate is about trust and relationships, not just transactions. She holds a Bachelor’s in Organizational Leadership from South Texas College but takes the most pride in being a mother to her two daughters. Outside of real estate, she volunteers at their schools and serves on multiple committees, including the Greater McAllen Association of REALTORS and the Rio Grande Valley Livestock Show Entertainment Committee since 2006. An award-winning RE/MAX agent with multiple certifications, Diana is fully bilingual in Spanish. She is dedicated to professionalism, attention to detail, and prioritizing her clients’ needs. With her, clients gain a trusted advocate to guide them through one of life’s biggest investments.

About

My priority is to get my clients to buy or sell their property with their objectives met. That communication is present in time and content. Customer service may seem simple, but it requires a real understanding of what is important. Real estate transactions are complex and it is my purpose to make them as light as possible.
