pam-postmaPam Postma, Vice President

Starting in 1979, Pam formerly worked in administration and accounting for Midwest Great Dane Trailers. Pam married her high school sweet-heart, Nate, in 1981 and was introduced to climbing later that year at a time when you didn’t really see women on the rock. Pam traveled from the east coast to the west coast climbing everything and trying to keep up with Nate. She participated in numerous local and national competitions meeting great people in the climbing industry. Climbing became the way of life. In 1995, Pam left her career of sixteen years with Midwest Great Dane Trailers to help with the birth of Vertical Endeavors, her husband’s dream.

During the growth stages of Vertical Endeavors, and in the early days when the company operated from the couple’s residential garage, Pam worked in almost all of the various jobs at VE. Pam takes care of the financial and HR aspects of the business today. In her free time, Pam enjoys wind surfing with Nate, which results in vacations to the Hood River, Columbia River Gorge, and Caribbean Islands. She enjoys the beautiful country and of course scoping out the rock formations.

Noal Ronken, Training + Business Development Manager

Noal is currently the Training and Business Development Manager for Vertical Endeavors but was formerly the facility manager at the St. Paul location. His climbing career began on a beautiful line on the north side of a local crag dubbed the “REI Pinnacle” in Bloomington, MN. Despite these very plastic beginnings his climbing has now taken him as far east as the Red River Gorge in Kentucky and as far west as Smith Rock in Oregon. His tendency to jump on difficult boulder problems off the couch has led to just as many rumors of hollow bones as tweaked tendons. But his love for the sport and talking (extensively, as a many of never-enough words) about the sport is undeniable. Outside of climbing he enjoys running, paddleboarding, hiking, golfing, watching sports, attending concerts, playing guitar, writing music and exploring new corners of the Twin Cities.

Corrin Murray, Assistant Facility Manager

You could say Corrin’s relationship with climbing started in her early teens when she placed “climb Mount Kilimanjaro” on her bucket list; but, it may be more accurate to say it started at Vertical Endeavors. In 2013, Corrin was searching for a new sport: something challenging, exciting, and fulfilling. Rock climbing fit the bill and Corrin was hooked. Within the next couple months she became a member, applied for a Groups & Sales position, and climbed her way up the VE ladder. She continues to be challenged, excited, and fulfilled by the sport of climbing and the facility which introduced it to her. When she’s not climbing, you can find Corrin with her three dogs: camping, hiking, canoeing, biking, and habitually exploring the great outdoors!



Kevin Scott, Assistant Facility Manager

Bio Coming Soon

kristin_willey_bio_webKristin Willey, Group Sales, Programs Coordinator

Kristin started her relationship with Vertical Endeavors first as a member, then as an instructor, and now as the Group Sales and Programs Coordinator, enjoying every step of the way. She was first introduced to climbing in high school, but spending the majority of her time with responsibilities as captain of her dance team, climbing did not become a regular hobby until her college years. Kristin attended the Association Free Lutheran Bible School, Northwestern College, and Metropolitan State University with a certificate in Biblical Studies and nearing the completion of a bachelor’s degree in Human Resource Management. When away from the gym, she can be found camping, seeing live music, attending every festival within a 25 mile radius, or being pulled down the sidewalk by her abnormally strong black lab. Throw on a song with a good beat and it is impossible for her muscles not to begin twitching into some form of dance.

katie_heimerKatie Heimer, VEGA Coordinator + Head Team Coach

At some point in the past Katie was born and thrust into the ghetto of Minneapolis; immediately thereafter, and ever since, her bony knees have struggled under the weight of a wildly sarcastic and adventurous spirit; so much so that she is irreversibly pigeon toed. She was introduced to the outdoors at a very early age and the two have engaged in a passionate affair ever since. Climbing fosters a beautiful relationship that requires hunger and drive and a steady acceptance to move with rather than against and that is what Katie loves about it. As an extension of this, Katie is Head Coach of the Climbing Team at VE; enjoying the elation and challenges of sharing her love of rock climbing with youth. Her goal is to help develop exemplary members of the climbing community, and train young climbers into the sending beasts we know they can be! The best part about climbing, in Katie’s opinion, is getting outside, and as the Program Coordinator for Vertical Endeavors Guided Adventures (VEGA), she can’t wait to get you geared up to crush on real rock. When not managing, teaching, or coaching, she can be found gallivanting around the world’s wild places, petting all of the animals – all of the time, or drooling over artisan cheeses. Make her laugh and she will be your pal instantly.

Eric Berseth, Graphic Design + Marketing Specialist

Eric is a graduate of the University of Minnesota, Duluth, with a BFA in Graphic Design. He brings with him a passion for climbing and design. Eric’s first experience climbing was at a birthday party as a child. It wasn’t until recently that he rekindled his interest in the sport. He started back up with his brother in March of 2013, climbing weekly at VE Minneapolis, and has progressed to sport lead climbing outdoors in Red Wing, Minnesota.

You might see him in the gym as he frequents the VE Twin Cities locations. In his free time, Eric enjoys cooking, new music, camping, biking and skiing.
