About HSA

Our Story

Our Story

Jack A. Hearn opened his land surveying office in Athens, Texas in 1966. After his first day on the job in 1974, Mark Ferrell told Mr. Hearn that he wanted to buy this business. Upon Jack’s retirement in 1986, Mark got the chance, opening the first office under the name of Hearn Surveying in Corsicana, Texas, followed soon thereafter with offices in Gun Barrel City, Athens and eventually Palestine. Overtime it became more efficient to base operations out of one office, and Athens, Texas remains the home and hub of Hearn Surveying Associates. Many of the employees of HSA have been associated with the company for over 30 years and have continued to provide excellence in service through each iteration of this family owned and managed business.

Our Values

Our Values

In over fifty years of keeping customers happy, we’ve learned it’s essential to have fun, improve the lives of others, and take every opportunity to effectively and efficiently serve our trusted partners. At the heart of HSA is a commitment to being joyful, doing good and working hard. Surveying offers many benefits as a trade, not the least of which is working closely with several stakeholders over several years. Beyond serving the needs of these customers through our normal course of business, our team members also strive to serve their community in ways completely unrelated to their job description. Of course, at the end of the day, this is a business. Most of the time we are part of the larger business process of closing a real estate transaction. Because of that, efficiency is key. We will hustle to help you meet your deadline within your budget in order to achieve your goals. If at anytime during your relationship with our team, you feel we are not living up to these ideas, please let us know.
