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.
