Our Staff & Training
Jeff Greiner, Owner
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 40 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 has 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 Wildwater Ltd.’s four locations on the Nantahala, Ocoee, Chattooga, and Pigeon Rivers, Jeff had a dream to bring outdoor adventure to Asheville city limits. Under Jeff’s direction, ACA has grown from a few ziplines to a family adventure destination with 8 different activities.
Jeff has over 25 years’ experience as a professional ropes, zipline, and aerial adventure guide, trainer, manager, and owner/operator. Jeff is an 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.
Sheena Greiner, Co-Owner
Sheena Greiner is a full time elementary school teacher with a strong background and passion for special education. Although she will tell you that she is just a teacher and doesn’t know much about the business, her guidance and commitment to giving back and supporting the community has led to ACA donating over $200,000 over five years to numerous organizations including the NC Autism Society, Camp Lakey Gap (for youth and adults on the spectrum), Asheville GreenWorks, RiverLink, Buncombe and Henderson County Schools, and many, many more. She has also served as a business and education advisor at ACA.
Chad Clark, Manager
Chad graduated from Augusta State University with a Bachelor’s Degree in Psychology. After graduating from college he began his career in outdoor recreation and experiential education, working as a challenge course ("ropes course") leader and facilitator on St. Simons Island, GA. In 2001 he began working for a challenge course builder, Challenge Design Innovations, as a trainer, builder, and inspector. He spent several years traveling around the country inspecting zip lines and obstacle courses while also training staff to safely operate those courses.
In 2006, Chad became manager and eventually owner of the challenge course in St. Simons. The company, Peak Pursuits Inc. is an adventure based team building program provider. In February of 2015 he moved to Asheville to be closer to his family and pursued interests in outdoor recreation. Chad has worked at ACA since then as a zipline ranger and trainer, team building facilitator, and currently as a manager.
Chad chose ACA as his new home because of the family atmosphere and the wide variety of aerial and team building adventures offered. Asheville has proven to be the perfect place to feed his other passions such as hiking, camping, and bluegrass music.
Ben Seidman, Manager
Ben Seidman originally hails from South Florida where he grew up fishing the waters of the Everglades. In 2012 he graduated from Brevard College in Western North Carolina with a BA degree in Wilderness Leadership and Experiential Education. After graduating college and spending a few years traveling, he came to work at ACA as a ranger in the Treetops Adventure Park where he split his winter and summer months working as a guide here, and a zipline guide in Southeast Alaska.
Ben has a passion for the outdoors as well as health and fitness. In his free time Ben loves to take advantage of the area and can be found riding his bike in the forest or taking a dip in one of Pisgah's many natural swimming holes with his wonder dog, Stikeen. “Having to wear a uniform consisting of helmet and harness I don't feel the typical monotony of a desk/office job. You never know what kind of outdoor fun the day will throw at you.”
Nick Christofalos, Manager

Nick and his wife, Shelia, have one daughter Alexandra who rides for the Appalachian State University Cycling Team. As a family, they toured the National and State Park system in their 28 foot RV exploring the US from Maine to Washington state. Nick has been a strong advocate for cycling for many years as a founder a non-profit cycling club, a host/organizer for USA Cycling sanctioned events, a founder of a youth biking club, and a volunteer at countless rides and races.
