The Story of IC WOOD LLC: From Innovation to Impact
Behind every log shipped is a decade of engineering and a commitment to natural preservation.
The journey began in 2014, when IC WOOD LLC was founded to solve a critical gap in the market: the lack of authentic, structural, and safe natural environments for animals. To meet this need, the company leveraged a technical breakthrough years in the making—the proprietary "Inner Circle Wood Method."
The Evolution of an Innovation
A Decade of Solving Needs
Since 2014, IC WOOD LLC has successfully diverted 275 tons of wood from landfills, repurposing massive timbers into vital habitat features. The company's top-tier industry ranking is the direct result of providing a specialized solution that the world's leading institutions—including the Columbus Zoo and Shedd Aquarium—have relied on for over a decade. Today, IC WOOD LLC continues to lead the industry through dedicated Research & Development and expert consulting for zoo enrichment specialists and landscape architects nationwide.
"The goal has always been to provide a real-world alternative to a plastic-focused industry. Nature provides the best materials; I simply provided the technology to make them accessible and safe for everyone."
— Bob Kilgore, Founder & Inventor

Since 2014, IC WOOD LLC has been driven by a single question: Why use plastic and concrete imitations when the real thing is better for the environment, better for animals, and better for children? Our mission is to bridge the gap between rugged, reclaimed timber and safe, structural design."
What sets IC WOOD apart is our proprietary hollowing process. Developed by our founder, this specialized technology allows us to take massive, reclaimed trees and transform them into lightweight, structural forms. We maintain the natural bark, scent, and texture of the wood while ensuring the interior is clean, safe, and ready for use in world-class habitats and natural playgrounds."
Over the last decade, we have become the trusted partner for over 100 premier institutions across North America. From the high-traffic exhibits at Disney’s Animal Kingdom and the Smithsonian National Zoo to the sensory-rich playgrounds of Natural Playgrounds NH, our logs have set the standard for durability and authenticity. We aren't just a supplier; we are a key partner in creating environments that inspire.

As Katya aged at the Seneca Park Zoo, her caretakers used a variety of specialized enrichment to keep her physically active and mentally sharp. Because she lived to be 20 (the oldest of her kind in an AZA-accredited zoo), much of her enrichment was adapted for a "senior" tiger.
Give a Giant a Second Life.
Many zoo residents, like senior Amur tigers or active primates, benefit from the tactile, sensory-rich experience of real wood enrichment. When you sponsor a log, you aren't just buying equipment—you are providing a natural sanctuary.
