Howdy, Great to Meet You


We are a crew of product designers, wordsmiths, adventure advocates and outdoor enthusiasts based in sunny Austin, Texas, who believe greatly in the value of experiencing the world through our core values: adventure, community and love. Everything we do, every product we create, is working towards our mission to equip and inspire others for life changing adventure.

Haley RobisonChief Executive Officer

Haley was drawn to Kammok's vision to "equip and inspire" and believes in the power of well-designed product to enable and encourage life changing experiences. With the increasing concentration of people in urban centers, she aspires to increase outdoor engagement by building a brand that encourages a city-to-trail lifestyle and makes the outdoor experience accessible for everyone.

Whether traversing the Wyoming range or leading a design workshop, Haley gets fired up creating experiences that foster community and build self-knowledge. She recently completed a joint Masters degree in Business and Education from Stanford University. In her past life, Haley worked as a consultant, field instructor, organizational designer, sous chef, and bootcamp instructor. She has a special fondness for ice breakers, red rocks in Utah, and everything green, even broccoli.

John DowProductsmith

John, a true southern gentleman, grew up in the rolling plains of Auburn, Alabama, or what his grandfather used to call “The Promised Land.”  His passion for the outdoors has been an integral part of his upbringing.  Whether it be his road to Eagle Scout, a weekend trip or day hike, John just loves being outside.  John’s experience and gifting in textile based design and product development has equipped him to allow others to experience life-changing adventure through some of Kammok’s newest products.  John and his beautiful wife Rachel, an Austin-native, were married in 2013. They enjoy running together, listening to live music, and “doing life together” with friends and family.

He has always dreamed of having a nonstop “Amazing Race” style adventure traveling the world.  Adventures would include hiking in Patagonia, backcountry skiing in Alaska, sailing in the Mediterranean, and zip lining through the Amazon rainforest.

Travis PerkinsMOB Communications

Travis was born and raised deep in the piney woods of East Texas. Although he is now based in Austin, TX, his passions for traveling the world, photographing the wild earth, & serving those in need have taken him from the Lone Star State to the jungles of Mexico, the mountains of Central & South America, and to the vast beauty of sub-saharan Africa.

Travis' life is a complex yet simple balance of hard work, intentional rest, and abundant joy. His focus on the strength of community within this balance has brought him to the role of customer experience associate. When he isn't cultivating community at Kammok HQ, he can be found climbing the limestone crags of Central Texas, planning his next adventure over a hot cup of coffee, or hitting the trail with camera gear in tow.

Jason MillerSales Lead

Jason was raised near Kammok HQ in the great city of Austin, Texas. His passion for the outdoors has taken him from the jungles of Northern Thailand to the high alpine environments of the Peruvian Andes to experience and share adventure. He can now be found exploring the rivers and forests of Central Texas with his wife Brooke, his four kids (Deianna, Mahliea, Tigo and Irie), and his Australian Shepherd Kona. Throughout all his adventures, Jason's commitment to education, service, and inspiring others keeps him moving.

Before joining Kammok, Jason worked as an independent rep for large brands in the Outdoor Industry and as a adventure travel guide based out of Chiang Mai, Thailand. He loves to bring together his real life product knowledge with his passion for business, and believes that selling outdoor gear is a way to inspire people to get outside and enjoy the nature that exists around them. He joined the Kammok team because of these shared values and is excited to equip and inspire people through the products we create!

Grace MuellerMarketing

Grace is a wild believer in adventure, community, and love as the fixings for true life-change. She feels most small (and therefore has the most wonder) when surrounded by the great outdoors with no-screens, Snapchat filters, or cell-service. She’s a lover of words, an avid day-dreamer, an ENFP, and a Type Three enneagram (anyone else out there?!). Her heart beats to spend time in the mountains, under pine trees, or biking the hills of Austin.

Born in Chicago, Illinois but a Texas native for 15 years, Grace graduated from the University of Texas at Austin with a degree in Corporate Communication and a minor in Social Entrepreneurship + Non Profit. She is passionate about using business as an avenue to enrich the lives of others and leave a positive impact on the world. When Grace isn’t shaking things up in marketing at Kammok, she can be found eating tacos at Granny’s, reading in a favorite Austin coffee shop, adventuring with her YoungLife girls, or cooking up something new in her kitchen.

Liz HarrounCustomer Experience + Operations

As a Dallas native, Liz quickly converted to the city-to-trail lifestyle when she moved to Austin to study International Business and Spanish at the University of Texas. Her travels during college included a summer doing volunteer work in South America as well as a semester studying abroad in Spain. Through her adventures, she realized the importance of community and environmental sustainability.

These days, she can be found riding her bike around town with her boyfriend Zach, planting veggies in her garden, or seeking out swimming holes and crags on the trail. Liz truly believes in the power of natural environment and movement to help foster self-awareness and gratitude. She strives to practice these virtues with humility both in her personal pursuits and in her service to others, including the Kammok MOBsters.


Gathering from all over the map the interns have brought many smiles, laughter, creativity and much resourcefulness to the Kammok headquarters in Austin, TX. With a large range of skill sets and strengths they are helping to bring adventure and love to more and more people each day. From finance to design they are making a difference in the everyday impact of Kammok.
