Mark Singleton

Executive Director

Mark Singleton joined American Whitewater as Executive Director in November of 2004. Under Mark's leadership, American Whitewater's conservation and access program has been refocused and transformed into River Stewardship, an integrated approach to the river restoration and protection work of American Whitewater. River Stewardship encompasses the three main mission pillars of AW's mission statement; conservation, access, and safety.

In 2011, The River Management Society awarded Singleton with the Outstanding Contribution to River Management Award. Mark is also the past Chairman of the Outdoor Alliance, a coalition of six human-powered outdoor recreation groups. The six membership groups of Outdoor Alliance have a long tradition of preserving public access to America's Outdoors. Members of the Outdoor Alliance include: Access Fund, American Canoe Association, American Hiking Society American Whitewater, International Mountain Bicycling Association, and Winter Wildlands Alliance. Collectively, the Outdoor Alliance has members in all fifty states and a network of almost 1,400 local clubs and advocacy groups across the nation. The coalition represents the millions of Americans who hike, paddle, climb, mountain bike, ski and snowshoe on our nation’s public lands and waters.

Singleton has over two decades of involvement in the marketing of outdoor activities and nature based tourism. From 1990 to 2003 Singleton led the marketing efforts of Nantahala Outdoor Center as Marketing Vice President. He is also a past board member of the Outdoor Industry Association and for seven years Mark represented the interests of outdoor recreation on the North Carolina Division of Travel and Tourism Board.

Mark and his wife Debby, a faculty member at Western Carolina University, and their two daughters live in Cullowhee, NC.


Kevin Colburn

National Stewardship Director

Kevin has been an avid whitewater boater for over 15 years, and has paddled rivers and creeks in almost every state with gradient. Raised in Pennsylvania, Kevin moved south to attend the University of North Carolina at Asheville where he earned a undergraduate degree in environmental studies, with an emphasis on field ecology. While at UNCA, Kevin co-founded the UNCA Paddling Club and avidly explored the regional steep creeks both on foot and in a kayak. Shortly after graduation Kevin headed west to the University of Montana to get a masters degree in environmental studies that was focused on stream restoration and ecology. Montana proved an excellent base to paddle wild multi-day rivers, and to playboat on the Clark Fork and Lochsa. In 2001, Kevin was hired as AW's Eastern Conservation and Access Associate to tackle several tough dam relicensings and other projects across the east. Based in Asheville again, Kevin quickly developed a skill set focused on river management, negotiation skills, natural resource law, and regulated river restoration. Kevin became AW's National Stewardship Director in 2005, and now lives in Missoula, MT.


Bob Nasdor

Northeast Stewardship Director

Bob is based out of Massachusetts and has been an avid paddler of the rivers of the Northeast for the past 10 years. Bob joined the staff of AW in 2012.

Bob brings a wealth of experience to the position from his 20-year career as a public interest attorney. Bob served as the executive and legal director for several programs aimed at improving policies and services benefitting low-income and homeless families. Following these roles he served as the Assistant Attorney General for the state of Massachusetts and has since formed a private law practice. These roles honed Bob’s advocacy, legislative reform, legal, grassroots organizing, and outreach skills.


Dave Steindorf

California Stewardship Director

Dave Steindorf has been an active river advocate in California since 1997. As the primary negotiator for American Whitewater, Dave has gained a reputation as a consensus builder. He has been able to gain the respect of Agencies, NGO's, and Licensees while successfully achieving the goals of his constituents. He was a signatory to the Rock Creek Cresta Settlement agreement, along with past AW Board President Kevin Lewis, and AW Conservation Director John Gangemi. This agreement provide for the first whitewater releases in California. He has since worked diligently to organize and sustain the releases on the North Fork Feather River. Dave has a diverse range of recreational, professional and educational experiences that make him uniquely suited for his role at AW. Dave has more than 8 years of experience working on FERC Relicensing. Dave is somewhat of an anomaly, in that he has not only worked in an advocacy role but also as a consultant for several Utilities in the West. During that time he has had a role in 12 recreational flow studies as well as studies on angling and flat-water boating. Dave is also able to draw on his vast experience in a variety of recreational pursuits including having worked professionally in the areas of Paddling, Angling, Cycling, and Outdoor Retail. In addition to this breadth of experience Dave also has a degree in Economics and a Masters in Education. Dave was introduced to rivers at age 7, when his father put a fly rod into his hands. Learning to kayak later on was a natural progression from his childhood love of rivers. Dave's passion for river conservation issues inspired him to make a video, “More than Plumbing”, which won an award for best amateur video at the 2000 National Paddling film festival. Dave strongly believes that flowing rivers are an undervalued resource not only in this country, but also around the world. He feels that education is the key to river conservation. “Most of our progress on the North Fork Feather has been due to our ability to educate the other NGO's, agencies, and PG&E to the value of whitewater boating. However, the best way to improve people's notions about whitewater is to get them on the river. Couch Potatoes make lousy river advocates.”

Thomas O'Keefe

Pacific Northwest Stewardship Director

Tom first got his start paddling and playing in the water during early childhood canoe trips to the Adirondacks in upstate New York. After a brief diversion as a competitive swimmer and water polo player through high school and college, Tom came back to paddling and began his first serious whitewater while living in Japan and shortly thereafter became a full-fledged fanatic with the University of Wisconsin Hoofers. Tom has traveled across the country and around the globe in search of great rivers and most recently completed a final descent of the Yangtze River through the Three Gorges, before the gates were closed on the world's largest dam.

Tom began work with American Whitewater in a volunteer capacity in 1995 and served as a Regional Coordinator in the Pacific Northwest before joining the staff in 2005. Tom received his undergraduate degree at Cornell University before completing his graduate work in aquatic ecology at the University of Wisconsin where he received his PhD. Tom worked at the University of Washington where he coordinated research projects focused on the dynamics of nutrients returning salmon bring to river ecosystems and the structural development of riparian forests along large floodplain rivers. Through his work as a river ecologist, Tom gained experience working with resource agencies including the National Park Service and Forest Service as many of his research projects were conducted on public land. Tom has also taught courses in aquatic ecology, including watershed ecology and management, both at the university level and for youth programs. Bringing a wealth of experience to the organization, Tom contributes skills in river and fisheries ecology, teaching and outreach, grant writing, multimedia, web development, and inspiring local volunteers to help build American Whitewater's stewardship program. He is based in Seattle, WA and works closely with volunteers throughout the Pacific Northwest region on projects in Coastal WA/OR, the Columbia River watershed, Puget Sound, Fraser River watershed, coastal BC, and Alaska. In addition Tom covers project work in the Upper Midwest. And when the water's up, Tom still finds time to play on the water.

Megan Hooker

Associate Stewardship Director


Megan joined the American Whitewater team in February 2011 as the Stewardship Assistant. Her love of rivers was sparked while rafting classic western rivers like the Green, Rogue, and San Juan during her formative years. She also spent many weekends as a child at Lake Powell in Southern Utah, and eventually began to make the connection that her enjoyment of that landscape came at a great cost to the Colorado River. This realization fueled her passion for river protection and conservation, inspiring her to learn as much as she could about rivers – both in and out of school. She studied geology at the College of Wooster, environmental hydrogeology at Northern Arizona University, and later earned a master’s degree in environmental law from Vermont Law School.

Megan has experience with environmental law and policy, science, and non-profit communication and fundraising. Since earning her master’s degree in 2004, she has put her skills and passion for protecting rivers to work for a variety of non-profit environmental groups. Before joining American Whitewater, she worked for over three years as a legal and development assistant at a public interest environmental law center. She also has experience reviewing state agency files and drafting 60-Day Notice of Intent to Sue letters for industrial stormwater, municipal wastewater, toxic waste, and dredge and fill violations under the Clean Water Act.

As Stewardship Assistant, Megan supports the Stewardship Director’s river conservation and restoration projects throughout the West, with a strong focus on projects in California. She currently lives in Bend, Oregon, and when she’s not being a river wonk, you’ll likely find her on her yoga mat, hiking, or getting her hands dirty in her garden.

Carla Miner

Membership Director

Growing up in northern Montana, I learned to appreciate the beauty and majesty of the many rivers and lakes in 'big sky' country. The North Fork of the Flathead river and other rivers and lakes adjacent to Glacier National Park were the sites for many memorable days for my family. After living in Colorado and Washington for many years, I returned to my native Montana in 1998. I became associated with AW part time in 1999 in the Conservation office and assumed the additional responsibilities of Membership Manager in May 2003. Patrick and I now make our home in Utah and I enjoy gardening, biking, and needlework. Most of all, I enjoy spending time with my two children and three grandchildren. I am more than happy to assist members in any way possible and I am only an email or phone call away!
