James Henderson


Native West Texan James Henderson — who enjoys fly-fishing, camping and working cattle on the family ranch in California’s Sierra Nevadas — grew up on a small, diversified farm/ranch and graduated from Texas Tech University. 

As a high school student, he was a Texas State FFA Officer; in college, he was a member of Texas Tech’s National Championship Meats Judging Team. He worked for five years for Cattle Fax (a prominent meat industry organization) and in sales for a worldwide food and agriculture corporation, Cargill, Inc. in Minnesota.

In 2010, James started Prime Dirt, Inc. in the San Joaquin Valley, focusing on agronomy and livestock solutions at the biological level. The diversity in cropping systems in California provided James with a unique skill set. In 2018, he partnered with Greg Schilling of Back to Nature and Carter Smith to form Asido, LLC to expand into other markets across the United States.

A Certified Crop Advisor, James and his wife, Nicky, reside in Woodlake, California, where they farm walnuts, olives, citrus and run beef cattle. Son Reagan attends Texas Tech; daughter Jessica attends Montana State University. James is very involved in his community: president of Tulare Beef Boosters, deacon at Cornerstone Church, chair of Boy Scout Troop 309, board member of Tulare County Cattlemen, a member of the local Farm Bureau, coach of the area high school meats judging team and more.

Greg Schilling


Greg Schilling has worked with biologicals for almost two decades and is currently vice president of Back to Nature, Inc. and South Plains Compost, Inc., family businesses for more than 45 years. In addition to composting, he farms convention and organic cotton and peanuts and runs a cow/calf operation.

Asido founder, the late Jim Pruitt, was the first customer of the Back to Nature line. Years later, when Jim bought CXI, the Schilling family was the first customer to use Waste Away as the inoculate in their compost. 

“For our row crop or agronomics side, we apply the N-Texx Edge product before the planting of each crop,” Greg says. “That product contains a lot of degrading bacteria, so it’s very good at breaking down fertilizer elements into an organic or usable form.”

Greg likes to tell the story of how he became a believer in Asido’s biological products by trying them out himself.

The first farm we tested was one my dad and his uncle owned together. We wanted to put it back into grass. but the water quality was so poor that the soil had sealed off into a hard crust at the top, preventing absorption. They tried all kinds of ways to plow it or grow different cover crops with no luck. Then we decided to test the microbial product. It took two years, but the change was amazing! Trying to walk on the soil now, I would sink down to about my mid-calf. I mean, it opened that ground up that much!”

Greg graduated from Texas Tech University with degrees in animal science and education. He was a member of the 1999 National Champion Texas Tech Meats Judging Team. Greg lives in Slaton, Texas, with his wife, Lacy, and their three children: Kelsea, Grant and Koleson. He has been a member of the Slaton ISD Board for 12 years and is a past member of the Peoples Bank Business Advisory Board.

Carter Smith


An avid bird and big-game hunter, fisherman, and general outdoors enthusiast, Carter Smith’s Texas roots run deep but he’s no stranger to the national scene. After decades spent conserving his home state’s natural treasures, he’s turned his attention to the world of biological solutions for American farmers at Asido.

Carter also serves as a partner and managing member of S2S Holdings, his family’s agricultural, oil and gas, and real estate investment company. He uses Asido’s products, naturally.

Carter formerly served for 15 years as the Executive Director of the Texas Parks and Wildlife Department (TPWD), an agency that manages state parks, inland and coastal fisheries, wildlife management, law enforcement, fishing/hunting/boating, and outdoor education/outreach. He was particularly active in private lands conservation, state park funding, acquisition of additional state park and wildlife management areas, Children in Nature initiatives, myriad fish and wildlife conservation issues, and coordinating the state’s conservation response and investments along the Gulf Coast following the Deepwater Horizon Incident. In addition, he worked closely with the Texas Parks and Wildlife Foundation to leverage significant private philanthropy with public resources to advance state fish, wildlife, and park related conservation priorities.

Prior to his role at TPWD, Smith was the Texas State Director for The Nature Conservancy, where he led the Texas team in protecting important habitats in areas like the Devils River, the Edwards Aquifer, the Laguna Madre and the Davis Mountains.

A native of Central Texas, with degrees from Texas Tech University and Yale University, Carter has served on numerous conservation-related boards and advisory councils, including as Chairman of the Association of Fish and Wildlife Agencies and President of the Southeastern and Western Associations of Fish and Wildlife Agencies. He is a member of the Texas Order of St. Hubertus, the Boone & Crockett Club and a lifetime member of the Texas Bighorn Society, the Dallas Safari Club and the Houston Safari Club.

Smith sits on the boards of directors of Jefferson Bank and AgriCapture, and serves in an advisory capacity to Lee and Ramona Bass on various conservation, wildlife and land-related matters. He resides in Austin with his wife, Stacy, and their son, Ryland. They attend Woodlawn Baptist Church and are active in managing and enjoying their farm and ranch holdings in the Hill Country, north Texas and in central California. 

Lee Rivenbark

Strategic Advisor

Lee Rivenbark retired in 2018 after almost 21 years with Bayer, most recently as head of seeds for North America for Bayer Crop Science LP, based out of the Seeds Innovation Center in Lubbock, Texas, where he and his family lived for 14 years. Lee currently resides in Auburn, Alabama, with his wife Camille and works as a partner of Ag World Advisors and volunteers at Auburn University in various roles within the school of agriculture, focusing on leadership skill development.  

Lee grew up on a small row crop and cattle farm in southeast Alabama, which gave him a lifelong appreciation for production agriculture. He graduated from Auburn University with an agricultural business and economics degree, then worked at a fertilizer dealership until landing a position with the University of Georgia as Calhoun County Extension Agent. Lee then joined Helena Chemical Company where he held several positions in sales, retail management and product management throughout the Southeast and Midsouth. 

In 1997, Lee accepted a position with Bayer Crop Science and led the commercial launch of the FiberMax cotton seed business. He held several positions within the company in marketing, sales management, operations and general management within NA and Globally for multiple crops. In addition, Lee served on the Global Seeds Leadership Team, U.S. Business Crop Protection Management Team and the North American Leadership Team.

Erin Clark

Regional Sales Manager
Animal Agriculture and Environmental Division

Erin Clark grew up on a Georgia farm that had “a little bit of everything,” including active management for duck and dove hunting and sustainable animal production.

Active in 4-H through school, Erin attended Berry College and the University of Arkansas, earning a bachelor’s degree in animal science in 2014. After graduation, her career has centered around poultry production at commercial operations such as Tyson Foods and Cobb Vantress. Erin says she noticed that birds’ immune systems weren’t as resilient as they used to be (both broiler and breeders) — her passion became figuring out the reason and the remedy.

“Throwing antibiotics at everything was not the solution, they mostly only helped with secondary infections from a viral infection,” Erin says, “I went down the rabbit hole doing research and realized all body systems (especially the immune system) benefit from a strong gut. That can be best accomplished by adding probiotics.”

Today, Erin has her own family farm with her husband, former Marine Josh Clark, and their two young children, Ellie and Lawson. When the kids aren’t playing ball, the family works happily together gardening and raising beef and pork, focusing on sustainable, regenerative farming. Ellie and Lawson are involved with 4-H as well, naturally.

Erin’s previous experience in poultry live production allows her to clearly understand the issues Asido clients face with breeders and broilers and can support them in their effort. She says there’s not always one answer to a problem in live production, so she prefers trouble shooting from different perspectives.

“I’m really elated to be able to work with the wonderful people at Asido and support the goals there,” Erin says. “Agriculture is my passion — I love being able to talk to people about solutions within this sector.”
