Mark Thelen

President
Landmark Landscapes
Shortly after graduating from the University of West Georgia and the Dallas Theological Seminary, Mark joined his father and brother in launching Landmark Landscapes—more than 30 years ago. He started from the ground up; quite literally, in the field! Over the years, Mark learned the science and nuances of making things grow for customers. But he was also a natural leader who learned to “grow” people as well. He has a knack for recognizing individual strengths and putting them to work. He can bring out the best in each person and helps them thrive both professionally and personally. Now, Mark is at the helm of the company, striving every day to educate, motivate, and inspire greatness in his team. He holds a high standard of excellence and doesn’t settle for mediocrity—in his people or any aspect of the business. He believes this is what sets Landmark apart. When not leading the team, Mark resides in Roswell and enjoys golf and flying planes. It’s no wonder he’s been so instrumental in helping Landmark take off to become the prospering company it is today.
