Meet the team

Terrier Tenacity is an independent design & marketing agency in downtown Loveland, Colorado. Founded in 2003 by Jackson Whelan to provide web design and development services. Our core team of creative thinkers is mutually obsessed with the intersection of design, marketing, and technology.

Jackson Whelan


Jackson is a designer and developer who built his first website in 1999. During a slow summer at a ski resort job, he taught himself HTML and CSS using a text editor on a PC with no internet connection. Since 2003 he has been providing expert WordPress development services, creating hundreds of custom websites for clients large and small. He lives in downtown Loveland, Colorado with his wife and tenacious terrier. When he’s not working to achieve success for his clients, you’ll find him on the local bike trail or headed to the mountains for a hike.

Julie Adams


After a successful career in the equine reproduction industry, Julie found her creative side through photography, digital marketing and communications for equine businesses across the country. She brings her artistic vision and style to design and development projects at Terrier Tenacity. Julie is a lover of food, travel, things with fur, chasing the light and long hikes near her home in Loveland, Colorado.

Jackie Clarkson

Project Coordinator

As a self-proclaimed lover of deadlines with a dedication to the details, Jackie has spent the last eight years of her professional career honing her digital marketing and communications skills with ad agencies and in-house teams. She guides Terrier Tenacity's clients through their projects from start to finish, helping them understand each step of the process. Jackie lives in Loveland, Colorado, with her three dogs, gecko, and very patient husband. When she isn't working, you'll find her with a camera in hand, hiking, camping, or enjoying one of Colorado's many breweries.

Kate Edberg


As a creative professional with a demonstrated history of simultaneously succeeding in photography and marketing, Kate is passionate about helping small business owners grow their brand through altruistic imagery and wordsmithing. She lives in Fort Collins, Colorado with her husband and two boys.


Brianna Eason

Content Manager

Brianna joins the team at Terrier Tenacity as a virtual assistant and content manager. Her background in web design, content management, and social media marketing brings varied skills to help with projects across the board. She left the Iowa winters for the mountains of Colorado Springs and spends time exploring nearby trails, playing the cello, and learning Spanish.


Madelyn Erb


Madelyn is a detail oriented person who makes sure things run smoothly. When she's not helping us balance our books and stay on top of billing requests, she's a landscape architect. To relax she likes to retreat to her studio and make lampwork glass beads or take a stroll with her two tenacious terriers.
