Lizzy and Doom, owners of Four Corners Guides

Meet the Owners

With 50+ years collective experience in backcountry adventures and almost as much in the outdoor industry, Steve “Doom” Fassbinder and Lizzy Scully know what it takes to live and play in the world’s wildest areas. Out of a desire to share their passion with others, they created Four Corners Guides. Doom and Lizzy met through outdoor industry connections. They climbed “The Cruise” in the Black Canyon on their first date, the “Naked Edge” in Eldorado Canyon shortly thereafter, and after soloing to the summit of the First Flatiron on election day 2016 decided they were a match made on granite. The summer after Lizzy moved to Mancos, the duo bought an idyllic, remote cabin and 35 acres at the tip of Weber

Mountain. Obsessed with adventuring, it only made sense for them to pursue a dream they both shared of running a base camp, now called Scullbinder Ranch, and adventure guide service together, with Steve the head “Bikeraft Guide” and Lizzy running the business. The couple thrives on sharing the wild, remote places they know and love and the challenging experiences they regularly have with friends, family, and now, with you, Four Corners Guides’ guests. Join us for an extraordinary adventure.

Steve Fassbinder

Founder, Head Guide

Steve Fassbinder, known as “Doom” among his friends and within the tight-knit mountain bike industry, started adventuring at age 14. He raced single-speed mountain bikes until his 30s, but eventually started focusing on exploring huge backcountry landscapes. Passionate about creative, human powered, low-impact travel, he’s likely explored more of the Southwest United States by both bike and packraft than any other person. Read about him in Outside mag, and follow him @republicofdoom on Instagram. Get to know Doom!

Thad Ferrell

Head Guide

Thad spent his childhood traveling out West to fish with his parents. They planted a seed, and whether the branches led to climbing, biking, hiking, fly fishing, or floating the rivers of the West, he knew this was where he wanted to put down roots. Always thinking about fly fishing, and after a very narrow brush with death in 2017, Thad decided to move forward with his dream of starting a guide service. Join Thad on the San Juan River!
