Our People

Cat Alletto: CEO | Facilitator | Producer


Cat began her career in the outdoor experiential industry in 1998 as a trip leader and trainer for Backroads Active Travel Company leading people on adventurous vacations in unique destinations. In 2006 she shifted gears and brought her passion to the corporate space as a lead facilitator at CBST Adventures. Now, at Spark4, she connects with executives and leaders that want to build an energized culture of success across their organization. Over the years she has led and facilitated hundreds of group, leadership and team building activities. She works tirelessly behind the scenes to design and execute custom programs and leadership development experiences that seamlessly integrate active learning methods and destination-inspired activations.

Drew DeMarie: Managing Director | Facilitator | Trainer


Drew is Spark4’s swiss-army knife, equally talented at leading groups, inspiring teams and running the behind the scenes logistics. Drew began his facilitating and training career in the nonprofit space in 2005. He has created dozens of online and in-person training curricula for staff, volunteers, youth and families. Additionally, he has delivered Open Space Workshops for over 600 participants, has experience leading wilderness backpacking trips, and is a certified ropes course director. Prior to nonprofit work, Drew was a lacrosse coach in England and continues to support the game today as an Assistant Coach at MSU-Denver. With Spark4, he designs and facilitates experiences for businesses, organizations to support them with change management, teamwork, leadership development and beyond.

Ari Hunniford: Co-producer | Facilitator


Ari makes the magic happen. Whether she is on the mic as the emcee rallying the troops, or behind the scenes handling the logistical details, you can count on her giving it 100%. With a background in non-profit fundraising, spiritual coaching, community building and theater, her diverse skillset compliments the team perfectly.

Natalie Raborn: 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.

Byron Swezy: Technical Director


Byron has logged 25+ years in corporate events and video production. He was a sound engineer and technical designer dating (way) back to his high school days. 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. Working with Spark4 means he gets to be at the top of his game in all of these areas of expertise! He is also the Co-founder and Owner of digiZuk and DragonFruit Video.

Jess Neiding: Project Manager


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.
