That is all due to our dedicated leadership team whose exemplary leadership and expertise are indisputable in the outdoor outfitter industry. Meet our team!


Jeff Greiner
Managing owner, Jeff Greiner and his family have grown up in the outdoor adventure industry. In 1971 Jeff’s parents started the first whitewater rafting business (Wildwater, Ltd.) in the Southeast U.S. on the Chattooga River. That small family business has grown into one of the largest and most respected professional outfitters in the United States.
The Greiner’s have been involved in setting industry standards for the outdoor adventure industry for over 50 years including river and forest protection standards for outfitters. The family also helped form the eastern and then national professional outfitters association (America Outdoors Association) created to foster awareness, education, development, and growth management for professional guiding services on public and private lands across the country. Jeff served on the national Board of Directors of AOA for over 10 years.
Growing up on the Chattooga River and learning the family business, Jeff loved sharing the beauty and adventure of the outdoors with Wildwater guests. In 2006, being the President of Nantahala Gorge Canopy Tours, Wildwater Ltd.’s four zipline locations on the Nantahala, Ocoee, Chattooga, and Pigeon Rivers, Jeff had a dream to bring outdoor adventure to Asheville city limits in 2011. Under Jeff’s direction, ACA has grown from a few ziplines to a family adventure destination with many different activities and with over 250,000 visitors.
Jeff has over 25 years’ experience as a professional ropes, zipline, and aerial adventure guide, trainer, manager, and owner/operator. Jeff has been ACCT certified CCM (Challenge Course Manager) with a special emphasis on zipline operations and management.
Living in Asheville, Jeff and his wife, Sheena, have three children that love hiking, camping, paddling, skiing/boarding, and sharing anything related to the great outdoors.

Lauren Brown
Lauren joined the Adventure Center of Asheville in 2020 in many roles, and now oversees The Summer Camp Program.
In 2022, Lauren’s dedication to the ACA Summer Camp Program led us to be accredited by the American Camp Association! Accreditation means that our camp cares enough to undergo a thorough (up to 290 standards) review of its operation — from staff qualifications and training to emergency management. While we have been dedicated to the health and safety of your campers for almost a decade, accreditation is a parent’s best evidence for a camp’s commitment.
Since joining ACA, Lauren has been able to attend the Association for Experiental Education, the Association for Challenge Course Technology, and the America Outdoors annual conference. Participating in continuing education in the field has inspired her to create a welcoming, educational, and fun-filled environment for all of the campers that she works with.
Lauren is from Virginia and grew up exploring her backyard and creeks as much as possible. Starting as a Counselor in Training for a Scouts BSA camp in 2008, she has been working at camps for over 12 years, serving as Camp Director for 4 of those years.
After earning her B.S. in Environmental Science from George Mason University and interning for the Smithsonian Conservation Biology Institute for Forest Ecology, Lauren wanted to merge her passion for the natural world with working with youth through outdoor education.
Lauren started as an Instructor at Mountain Trail Outdoor School in North Carolina, eventually serving as the Program Director. There she collaborated with school groups and teachers to develop goals and schedules for their students to ensure a positive outdoor learning experience. And when she was lucky, still got to teach about the wonderful world around us!
Moving to Western North Carolina has allowed Lauren to enjoy all her favorite things: backpacking, river floating, bluegrass music, and a great sense of community and connection.
