About Us

Celebrating-20-Years-wYou will have to look long and hard to find a company like TDI. Previously known as Turf Doctor, Kevin Bryant set out on an adventure in 1994 to start a company that did what no one else would. His approach was simple. Design lawn programs to manage the microorganism component of the soil in order to promote and sustain the health and well-being of the turf and ornamentals that are grown in that soil. He placed such a great importance on microbiology because without an understanding of this science, no sustainable management strategy could truly be formulated.

After hundreds of soil samples and tests, Bryant found the perfect formula for success. The answer was quite simple, Biological Lawn Care. It is a holistic approach combining the best of chemistry, physics, biology and microbiology with sound soil management practices. It addresses and solves weed, disease and insect pest problems at their root causes rather than merely masking the symptoms with poisonous chemicals.

Fast forward twenty years. Bryant along with his team of knowledgeable employees have grown to be leaders in their industry. Not only for the most modern and reliable products and techniques they use daily but also for their safe, conscientious and educated specialists.

John S. - Gurley, AL

“Since moving to Madison in 2005, we at one point tried every lawn service company with dismal results. A few years back, we switched to TDI and signed up for the yearly plan. I can’t tell you how satisfied we are with your commitment to service excellence. Coming from a business background, you are doing it right!”
Carlos F. - Madison, AL



“I contacted TDI because my yard was in such a bad state after a ‘do it myself’ experiment for 2 summers. This was after many years of using another company with fair results, but with lots of effort by them to sell me additional services. I researched our area for lawn care ‘specialists’ and was first attracted to your biological approach and logic based lawn applications. The results were absolutely amazing. Within 6 weeks, my yard was greener and thicker than it had ever been – and almost weed free. And all of this with less impact on the river, lakes and streams. So thank you for excellent service, your ethical company and your professional service people. It has been such a pleasure to work with you!”
Robert M.- Decatur, AL

“We've tried other lawn treatment services in the past with no results. We had given up and we're going to do it ourselves until someone highly recommend TDI. TDI has far exceeded our expectations from communication, pricing, services offered and overall results. An absolute fantastic company across the board.”
Eric S. - Hampton Cove, AL

“TDI is the best in lawn care treatments. All the staff is very professional. TDI backs their services 100%.”
