Grimpi Is...

The Esperanto word for "climb". This language was designed to unite people in 1887. The word "Esperanto" itself means "hoping one". These concepts speak to the heart of what we are.  

We are a family-based company that grew out of our life experiences. Avid climbers for many years, we have had the honor of introducing the sport to people from all over the world. This began with friends and family in the early years, along the climbing routes of coastal California. We then took it with us to New England, where the climbing experience was vastly different.

After settling Idaho, we opened a school focusing on arts and music. We felt that bringing students from around the world to create and work together was imperative to our mission. We soon discovered that when we introduced climbing as an activity to them, we were creating instant bonds. The language of climbing, camaraderie, trust and teamwork involved in climbing brought us closer to these students and sparked an interest in curiosity in them that they took back to their home countries and introduced their own friends and family to in return.

Through the years of climbing all over the country, we realized that positive impact of climbing on humans was being met with an equally negative impact on the environment as well. Visitors to these spectacular parks were being inundated with the "graffiti" of white chalk marring these beautifully colored vistas. We realized that since climbers were responsible for this blight, it should be up to climbers to create the solution. We began working on a solution that made environmental, aesthetic and functional sense. Grimpi was born, solutions for climbers, by climbers. 

As our chalks begin to grow in usage and reputation, we are hoping to demonstrate our commitment to minimal impact that may allow for greater climbing access as guardians of these areas recognize this commitment. As an extension of our commitment, we will be donating a portion of our profits to the Access Fund. A non-profit group that is dedicated to protecting and conserving public lands, climbers access and route safety. 

Donald has been "grimpi" since birth-but was not bitten with the climbing bug itself until, at 23, he and his brother-in-law thought they could have some fun with a harness and truck rope. He quickly learned that this was not the proper "technique", and has been learning and passing it down for almost 25 years.

Like all things in our lives, our Grimpi team is made up of our extended family of climbers

operations & development

Nick has been an avid climber his whole life. He was first strapped into a harness at the age of 18 months old. Trees, roofs, rocks, fireplaces- if it stood still long enough, he would try to climb it. 

He pushed back against the constraints of ropes, and eventually transitioned into bouldering as a teen. We haven't been able to keep up with him since.

International Liaison

Jean-Baptiste "Pierre"came to us as an exchange student when he was 16yrs old. He took to climbing  like he took to the family: instantly! 

He brought his passion for climbing back home with him where he shared it with his father and sisters.  Climbing has become more than a sport for him, it is now a part of his identity.

He was there when the colored chalk idea was born, and has been invested in it ever since.

As soon as he was old enough

to join his dad and big brother, Noah was up for the adventure. He was especially fond of climbing the old stone bridges in New England. He showed very little fear of heights from an early age. 

As the extrovert of the group, he made friends whenever possible and really exemplified the idea of climbing as community for his family.

Marketing & Sales

Martin is the consummate lover of adventure and adrenaline. He has lived all over the country and has come to appreciate the unique nature each holds.  He became a member of the Grimpi family, when, at 20, Noah introduced him to rock-climbing.  He's been one of the boys ever since. 

He is always on the lookout for his next adventure, hike or ascent; making friends everywhere he goes.

Our Philosophy

Climbing requires a special type of camaraderie. A group of like-minded people, working together for a common goal. A sport reliant on cooperation over competition, where everyone plays an integral role.  This is what appealed to us most when we first began almost 25 years ago. Since then, we have introduced students from around the world to the sport, initiated new friends into the fold and developed a great circle of people all thanks to what climbing teaches.  

Our company grew out of our natural love for climbing and the community that developed through the sport. Providing conscientious products, made with climbers in mind, and with an eye to the beautiful landscape we are responsible for protecting.

That is what led us to our motto "Grimpi Co; Where Co stands for more than just Company".
