“I feel at home along the East Fork of the Trinity River in the heart of the Blackland Prairie, it reminds me of where I grew up in east Mississippi along the Tombigbee River.  Through my enduring passion of man’s stewardship of the Earth, I envision leading the Wetland Center to become a premier example of environmental education with a strong focus on habitat and water conservation, public education, partnerships, and wetland research.  I look forward to sharing the history of John Bunker Sands and teaching about the importance of the East Fork Wetland Project.” – John DeFillipo
