Grover & Charlotte Hillbolt started Round Top Real Estate in 1988

The original owners and fondly known founders Charlotte and Grover Hillbolt, purchased their Round Top farm in 1962 when only a handful of Houstonians had found their way to the rolling hills of South Central Texas. In 1988, they established ROUND TOP REAL ESTATE and continuously offered their professional knowledge and experience, providing the foundation for the overwhelming success of the company. In 2017, they decided to pass on the reins of ownership to a new team of three who are passionate about country living.

The Tradition Continues:

Frank Hillbolt, the Hillbolt s son, Lisa Mayer and Lilla Blackburn-Sivekare the new owners. Frank Hillbolt joined his parents at the real estate company in 2002. Lisa Mayer began her real estate career with ROUND TOP REAL ESTATE in 1996 while Lilla Blackburn-Sivek, who s career included working with Martha Turner Properties and John Daugherty Realtors in Houston, joined ROUND TOP REAL ESTATE soon after making a permanent move to Round Top in 2008. Together this experienced management team continues to work diligently in positioning ROUND TOP REAL ESTATE for its future. As Round Top and the surrounding communities grow and new generations seek the same solitude as those before them, ROUND TOP REAL ESTATE continues to offer a remarkable group of agents committed to those seeking the joy of a small-town setting and the beauty of a quiet country evening.

I grew up on a ranch in Grimes County, Texas and have a true love of the land with a great appreciation of our area and it's many advantages. In October of 1982, I married Monty Mayer, a 5th generation Fayette County resident. We have lived in the area for 28 years, and Monty's knowledge and background of the area is a wonderful resource for me. We have two wonderful children, Adam and Claire. Both are graduates of Round Top Carmine High School. Both Texas Aggies, Adam graduated with a degree in Agribusiness in 2009, and Claire is currently enrolled in Mays Business School.

While earning my BBA in Marketing from Texas A&M, I became a real estate agent and obtained my broker's license in 1986. I have been with Round Top Real Estate for the past 15 years and have consistently been a top producer. I am currently serving as President of the South Central Board of Realtors.

Outside of my family, community involvement is a high priority for me. My service to the community consists of the following:

  • President of South Central Board of Realtors
  • Secretary Carmine Lions Club
  • A director of Round Top Carmine ISD Education Foundation
  • A director of Round Top Family Library Board
  • A member of Round Top Chamber of Commerce
  • A member of the Carmine Chamber of Commerce

I love what I do, and my background enables me to answer many questions from first-hand experience and knowledge. My job is to determine my client's wishes and needs by finding the perfect home or property that fulfills their criteria.
