OUR team

Christian Robinson

Founder, Operations Manager

Christian was born and raised in Hawaii where he spent most of his younger years surfing, hiking, and camping on the islands of Oahu and Kauai. Growing up in Hawaii was always an adventure and these experiences cemented his love for the outdoors. In 2004, Christian moved to Southern California and immediately stumbled across a local climbing gym, just a few blocks from his home. He was instantly drawn to the sport and started climbing regularly at the gym during the week and outside at various crags throughout Southern California on the weekends. It wasn't long before he was traveling across the country to climb at many of the best climbing areas that the United States has to offer. In 2007, he met Yoli, the love of his life, and together they traveled the world, climbing at some of the best climbing destinations on the planet. Christian is happy to call Knoxville home, where he lives with his wife, son, and daughter. He loves the awesome climbing and great people who frequent the Obed, less than an hour away from Knoxville. He enjoys sharing his love for climbing with his family and is excited to be teaching his children about the sport that has given back so much. When he's not climbing, Christian enjoys paddle boarding, surfing, hiking, camping, and traveling.

Yolanda "Yoli" Chen


Yoli first discovered climbing while attending college in Kansas City, MO. After learning the ropes at a local climbing gym, life and school took over and she put climbing aside for six years. After moving to California in 2005, she reignited her passion for rock climbing and explored the multitude of crags in the Southern California region. It was there that she found yet another love, her husband Christian, and together they started traveling all over the world to climb. Now, after a decade, two moves across the country, and the addition of two mini-crushers to their family, they have started their next adventure here in Knoxville, TN. Aside from climbing and being a part of this amazing project, Yoli works at East Tennessee Children's Hospital, loves photography, culinary arts (mostly the eating part), snowboarding, exploring the outdoors, and traveling.

Woodrow "Woody" Miller

Co-Owner, Construction Coordinator

Woody was raised in Charlestown, West Virginia, and grew up skiing and hiking in the Appalachian Mountains. Woody developed a taste for adventure early in life and found an outlet for it in the outdoors. During college, he took a semester off and kayaked 3,500 miles across the U.S., raising money for children's charities. He was also an environmental educator and worked with wolves in Minnesota. After living on a tall ship and operating along the Eastern seaboard, he moved to Montana, took up white water kayaking, and worked as a raft guide. Finally, Woody moved to St. Louis and became a construction foreman and continues in the field of construction with the start of his own company. Woody has always loved construction because it has been in his family for generations. Since St. Louis doesn't have an ocean, white water rivers, or mountains close by, Woody decided to take up rock climbing by going to a local gym. It was perfect and exactly what he was looking for: a fun and challenging sport with an amazing community that can be enjoyed for a lifetime. He couldn't be more excited to be a part of this project to help build that community in Knoxville.

Mackenzie Wilder


Mackenzie grew up in the small town of Weatherford, Texas. From elementary all the way to college, Mackenzie played competitive tennis. These days, she has hung up her racket and taken to the love of climbing and biking. While going to college in St. Louis, MO, Mackenzie began rock climbing at the local gym. During those 5 years, she enjoyed climbing and adventuring on the slabs of Jackson Falls. After graduating with a Bachelors in Photography and a Masters in Nonprofit Management, Mackenzie decided to keep up her work in the climbing world. Taking a job as a Gym Manager, Mackenzie left St. Louis for the West. There she spent two years crafting her sandstone Chaco sends out in Red Rock, Las Vegas, NV.  In addition, to her Chaco sends, Mackenzie loves biking both on the road and dirt (or on rocks out west). Mackenzie recently moved back to Knoxville to be closer to the Red River Gorge, family and friends, and to escape desert summers. She's super excited to be a part of the southeast climbing and biking communities and can't wait to connect the two and get involved.

Jonathan Carter

Assistant youth coach

According to Jonathan’s mother, he climbed out of his crib at six months of age and never really stopped. Jonathan grew up hiking and camping in the southern Appalachians with his family on a regular basis. This helped instill within him a deep sense of connection with the beauty and wonder of the southeastern climbing areas. However, it wasn’t until the fall of 2000 when Jonathan finally discovered rock climbing and immediately fell in love with the sport. Since then, he has shifted his focus multiple times between traditional climbing, sport climbing, and bouldering. The outstanding nature of the climbing community and the unique physical and mental challenges found in rock climbing all add to the allure of this activity that Jonathan hopes to enjoy for the rest of his life. Jonathan moves to Knoxville from Athens, GA with his wife and three young children to join the Onsight Team. He is indescribably excited to be a part of the Knoxville climbing community and to support local climbing through his role at Onsight.

Once she got started climbing she couldn’t stop and has now been climbing for almost two years. She self identifies as more of a boulderer but is always down for a good lead climb. She hasn’t been outdoor climbing yet (it kind of scares her) but she hopes to try soon.

Daniel Reiger front desk staff, Instructor

I grew up in Knoxville, I started climbing in 2006. Climbing quickly came to the forefront of my life. It is a beautiful melding of adventure, outdoor experience, exercise and camaraderie. I find climbing fosters a mental state of mindfulness, and a distinct feeling of living in the moment, I seek to learn from that feeling and incorporate those lessons into other avenues of life. The rock (or plastic) always has something to teach about oneself if one is willing to listen. In 2008 it led me to move to Fayetteville, WV, where I began working as a whitewater rafting guide on the New and Gauley rivers and found whitewater to be a unique yin to the yang that is climbing. I found in whitewater, a unique way to support myself and allow me to live in world class climbing destination, where the New river gorge, Meadow river gorge and Summersville lake were only minutes away. After 11 seasons I moved back to Knoxville in 2019 to resume school.

Mary duggan front desk staff, Youth coach

Mary grew up just outside of Knoxville in Alcoa, TN. She became interested in the outdoors when she started hiking regularly in high school, but it wasn't until her junior year of college that she found a love for climbing. While taking a semester long outdoor leadership course, she got to try out mountain biking, climbing and whitewater kayaking, and climbing stuck. She graduated from UT in 2018 with a degree in public relations and sustainability, and climbing has gradually become her favorite way to spend her time outside of work. Besides climbing, she likes to spend her time at concerts, coffee shops and the farmers market. She loves teaching others the outdoor skills she has learned and sharing the love of climbing!

Paige Flanagan front desk staff, instructor

From an early age Paige felt a draw towards climbing. As a climbing gym wasn’t really a “thing” where she was from her younger self resorted to climbing fences and ropes in the backyard. Everything changed when she discovered a new climbing gym had opened up near her home in Murfreesboro, TN. She got a desk job there and the rest was history. Since then she has learned the ins-and-outs of climbing and has gotten to the point where she can share her passion with others. Things were shaken up a bit when Paige decided to relocate to Knoxville for school and had to leave her local climbing gym but fortunately she was able to find Onsight where she was welcomed with open arms. Nowadays Paige enjoys pushing her limits in the gym and coaching her minis climbers to the top of the wall!
