Natalie Raborn

Coach & Project Manager

When you work with Spark4 you may see Natalie or you may not. If you do see her, you will know it, she is 6ft tall and although she's lived in the USA for a long time, she still has that Aussie twang (and sense of humor). If you don't see her, don't fear - she's always hard at work behind the scenes with an eye on the details, thinking 2, 3, and 4 steps ahead to deliver the best possible experience and impact for your group.

When not on project for Spark4 she runs her own health & fitness coaching business (HighRoadCoaching.com) and is also that person you'll see out on a mountain bike, winning world championships or pedaling crazy singletrack.

Natalie holds a B.S. in Business from the University of Denver an MBA from Illinois State University, and if things get real, we got you covered, she's a certified mediator.

Jess Neiding

Project Assistant

Jess is Spark4's figurative right hand, moving projects forward and high-fiving everyone along the way. Growing up on a farm in Wisconsin and surviving her formative years in Florida, her career path is just as varied. She started out in the arts and communications world but then shifted to finance and business management. Upon moving to Colorado, she followed her heartfelt creative side and merged that curiosity with her knack for analytical thinking and fondness for teamwork and good ole’ fashioned elbow grease. Even while she is leading her on-line publishing company, she still finds time to mastermind key projects for Spark4.

In the 90s he moved to Colorado where he founded an outdoor adventure and leadership training company. Since then he's been simultaneously honing his skills as an event producer, artistic director, and videographer.
