Meet the people behind Peak!

We’re a small company of passionate climbers and skiers. When you send an email or call, chances are you’ll talk to someone who has actually been on the objective you’re interested in. Each guide in the company has either completed the AMGA guide certification program or are working within the AMGA Scope of Practice.

Lance Sullins, Owner / Guide

Dear friend,
I believe this is the best job I have ever had. Owning and operating a small business is a huge commitment and I’m incredibly fortunate to have an amazing staff who make Peak greater than I could ever by myself. I’m very proud of our wide ranging experience and the variety of amazing places throughout the world we can climb or ski with you. I have no doubt you’ll enjoy your day in the mountains with any one of the professionals here.

My first climbing experience was with a large, guided college group in 2001. A half day of rock climbing at an obscure crag in Oklahoma was the beginning of my adult life as I know it. My career as a guide and ownership of Peak Mountain Guides is a vehicle to pay it forward. Sharing my love of climbing and my experience of travel around the world and almost all 50 states for climbing is why I’m here!
Sincerely, Lance

Steven Van Sickle, Instructor & Guide

AMGA Single Pitch Instructor Logo

Steven is a dedicated climber and motivated mountain guide who is conscientious and skilled at balancing the needs of clients in a safe and professional manner.

Originally born in New Mexico, Steven grew up travelling the world in an Air Force family.  After a thru-hike of the Appalachian Trail, Steven went back to New Mexico to attend school and found himself learning to climb on the steep granite cliffs of the Sandia mountains in northern New Mexico.  After years of big wall climbing and hard rock climbing in America’s great climbing areas, the natural progression to alpine climbing brought him to Ouray, CO.

In 2012, Steven began the Alpine Mentor program.  This unique opportunity allowed him to climb challenging routes in Colorado, Alaska, Canada, France, Italy, and India with world class mentors from around the world.  Today, Steven’s focus is on completing high altitude technical alpine routes on peaks throughout China and Asia, exploring every corner of the San Juan mountains he lives in, and completing the IFMGA certification process.
