We bring brands to life through experiences, events, activations and other badass ways.



What We Do

strategy | activation | sponsorship | event production

Highline has worked with the most sought-after brands for more than 20 years, creating and producing remarkable experiences, each anchored in strategy and driven by thoughtful insights.

Our company was born on the slopes of Vail Mountain, an inspiring location known for bringing international audiences together to share in a common appreciation for an environmental phenomenon.

As an industry pioneer, Highline has been creating similar phenomena, offering partners a door to an audience since before Experiential Marketing had been defined. Through integrity, creativity, and exceptional production, the company has grown into a world-class agency for conceptualizing, strategizing, and achieving cutting-edge activations for our partners.

Our team lives by its founders’ mantra to create an experience that leaves an impression on each individual that is more impactful than the view atop Vail Mountain, to capture, engage and retain relationships for our partners, and to love every second of it.


Every one of our relationships is built on trust


We have disciplined vernacular for process and are fanatics when it comes to strategy


The firepower of a big agency, and the flexibility of a boutique organization, we fight well above our weight


A vast network of brands and partners, operational excellence, and big-agency process and planning

What They are Saying

“Highline consistently produces high-quality events and activations. They understand our brands, our strategies and objectives and delivers above and beyond our expectations.”
Steve Jaccaud
Sr. Manager Sports Marketing at Anheuser-Busch

Adam Sutner
Chief Marketing Officer at Jackson Hole Mountain Resort
“You guys killed it. I’m super impressed with your level of organization, professionalism and quality of activation at each stop. Exactly what we were looking for. We couldn’t be happier.”
Gregg DiLeo

“The event presented many production challenges and Highline took these head-on. Their planning, attention to detail and overall quality of execution are unmatched.”
Jason Hines
Event Marketing Manager at Red Bull
“It is magical when you have a team that can take a concept and turn it into a reality.”

With a background in special events, she knows how to woo just about anyone with her wit, determination and savvy style. Katie has worked with our most demanding partners for many years. Her professionalism allows her to successfully manage and fulfill upon their requests, and to produce seamlessly executed experiences no matter what unexpected storms come her way.

Myriah Blair

Finance Manager
Myriah is our accounting nerd. She leads our team through the financial maze that is experiential, keeping a close pulse on our efficiency and budget management. With four kids at home, a team of ‘crazy kids’ at work, and various athletic endeavors on the side, she never backs down from a challenge. Myriah learned accounting when she was 14 years old and has past experience with a large property management company, several years in the tax industry and has owned a business. Though logical and calculated in the workplace, Myriah has an adventurous, daring and spirited personality. She brings light-heartedness to our team dynamic.

After working in a boutique PR and marketing agency she has a unique perspective that elevates our team’s workflow. Lucy doesn’t take life too seriously, which is likely a result of her half Canadian heritage, eh?

After working on some of the world’s largest events including the PGA Tour, Peggy is thoughtful and thorough, leaving nothing untouched or unseen.
