When we launched Smart Outdoor Services in 2006, we saw a real need for active water management and useful, realistic, impactful water education.  We set out to change the way landscape water is used and perceived in the landscape environment.  Through education, consultation, and active water management, we solve problems in the landscape.  Most common side effects are reduced water expense, beautiful landscapes, and an increased irrigation intelligence, which from our experience is quite contagious.



The growing significance of water in our economy and in the green industry has led to the evolution of Smart Outdoor Services as a leader in water education and consultation. John and Amanda Griffin have earned the reputation of being able to deliver the results that clients want in protecting their landscape investment and reducing their water use.

Through service to their industry, volunteering expertise and efforts for local North Texas non-profits such as the Dallas Arboretum, Friends of the Katy Trail, and Turtle Creek Association, speaking at events about water conservation strategies, and educating their client base about the plant/soil/water relationship, Amanda and John continue their commitment to creating a more savvy irrigation consumer.
