Jeff Llewellyn

Jeff Llewellyn | Co-Owner

Jeff began climbing at a gym in his home state of Indiana. Soon after cutting his teeth climbing outside at the Red River Gorge in Kentucky he packed up and moved to Boulder, Colorado. Since then, he has taken up traditional climbing, earned a degree in Outdoor Recreation Leadership from Colorado Mountain College, and gone on to become a guide for Sylvan Rocks starting in 2014.

After the 2016 season with Sylvan Rocks, Jeff went back to the Front Range of Colorado and became the Director of Guiding and Development for Evo Mountain Guides in Louisville. Now, he finds himself back in the Black Hills again, guiding and managing Sylvan Rocks.

When he’s not playing on rocks, Jeff enjoys travelling and hiking with his fiance Mykel and their puppy, Sanchito. Otherwise he spends his time biking, snowboarding, and kicking around a futbol.

Hands down our best climbing day with a guide ever. Everyone had an opportunity to climb at their level and also challenge themselves. Our guide listened and asked questions to make sure he was delivering on how we wanted to spend our time and was thoughtful and engaging. We had fun climbing but also just being together as a family having an experience. I'd recommend Doug and Sylvan to any one.

Brandon was amazing, very conscious of everyone's safety, and great working with our group of 3 ages 8-67! A memorable day and so glad we did the 6 hour day in Custer State Park! The highlight of our trip and highly recommend!!

We had a great time climbing with Jeff at Sylvan Rocks Climbing School. The company is really well run and you can tell that they are fully invested in making sure you have a great time. The owners are guides themselves so they do everything they can to make sure you feel safe, challenged, and satisfied with your experience. We even went out during an unseasonably snowy day in September and had a blast. Highly recommended!
