About Us

Our History

Inner Mountain Outfitters (IMO) was born out of a passion for adventure gear.

IMO’s original founder, Alex Sproul, traveled the world and brought back regional wear and gear previously unavailable to the US. Established in 1984 in Virginia, IMO brought the idea of dedicated caving gear to the US caving and high-angle rescue markets.

In 2006, IMO moved to Georgia and ownership passed to Nina and Jeff Martin. The Martin’s are no strangers to the sport of caving, having been active members of the NSS and Dogwood City Grotto (DCG) for more than 14 years when they bought IMO.

Since 2006, IMO has continued to push the sport of caving and, more recently, encouraging adoption of Rope Access within the US. Their participation in SPRAT and first-hand knowledge of the needs of SPRAT trained technicians has catapulted IMO to one of the largest distributors of rope access gear and equipment.

Our Beliefs
Safety first, safety last.

We realize that our customers think of their adventures as “not just your average adventure,” but an adventure that will push them to their limits. That’s why we select the equipment that we bring to you. We choose our suppliers because we know that having equipment that you count on provides you with one less thing to worry about.

IMO Leadership

Nina Martin has wholly embraced her passion for gear of all kinds. Nina is a passionate business owner who is ready to take on the next adventure. Her no-nonsense approach to safety and fun-loving personality draws the best and the brightest to IMO.

In addition to Nina’s ownership of Inner Mountain Outfitters, she works with Over the Edge, a company that provides nonprofits with fundraising opportunities through allowing donors to go “over the edge” of a high-rise building within a metropolitan area. She knows her gear and loves teaching others.
