David is a historian focusing on the Great Wall. He specializes in bringing to life this rich, colorful, and sometimes salacious material for visiting groups. His article “Raid of the Scorned Mongol Woman” was recently published in a scholarly journal, and he has collaborated with the photographer Jonathan Ball on “China’s Great Wall: The Forgotten Story,” a series of oversized photographs of Great Wall battle sites that has so far been exhibited in New York, San Francisco, and Palo Alto. David has been profiled by Peter Hessler in the New Yorker, has appeared on the Today Show, and has been featured in two Discovery Channel documentaries. He holds a BA in Asian Studies from Dartmouth, an MA in history from Beijing University, and a JD from Harvard Law School. With the exception of three years in law school, he has lived in China continuously since the 1980s. Before he began full-time research of Great Wall history, he was a consultant at McKinsey & Company.

An avid hiker, Chad has led groups to many sections of the "wild" Great Wall, and has designed and led study abroad programs in various places in China including Tibet, the grasslands of Inner Mongolia, rural Guizhou Province, and the border regions of North Korea and Russia. Chad spent his undergraduate years studying Chinese religion and philosophy at UNC-Chapel Hill and University of Sussex before spending several months studying Zen Buddhism at South Korea’s Songgwangsa Temple. He later completed graduate work in Environmental Management, Asian Studies, and Development Sociology at Cornell University, and earned certificates of Advanced Chinese and Korean from Tsinghua and Sogang universities, respectively. His research and language studies were generously supported by Fulbright-Hays, Korea Foundation, and FLAS fellowships, among others.

Mike Cooper first came to China in 2009 as part of a team of volunteer teachers operating summer camps in four different Chinese provinces. Mike returned to China in 2010 to study Chinese at Beijing Normal University, and moved to China upon graduating from Dartmouth College in 2012. After moving to China, Mike enrolled in an intensive Chinese language program at Tsinghua University. In the spring of 2015, he obtained his Chinese driver’s license and has taken several long-distance road trips in China – including a trip in which he followed the Great Wall for 1,400 miles from Beijing to the western end of the Great Wall in China’s Gansu Province. He is an avid photographer and drone pilot, and has captured aerial videos and photos of many sections of the Great Wall around Beijing, and sections in Hebei, Shanxi, Shaanxi, Ningxia, and Gansu Provinces. In addition to hiking and photographing the Great Wall, Mike enjoys studying the history of the different sections and interacting with the locals living in the nearby villages. Born and raised near the Northern Rocky Mountains of Idaho, Mike developed a penchant for outdoor activities at a young age.
