Some of us found our way out West and some of us sprung up straight from the foothills of the Wasatch Front, but all of us call Utah home. Founded in Salt Lake City in 2005 by Troy Mumm and Jocelyn Kearl, Third Sun has helped hundreds of clients with web design, branding, and evolving in the digital world.
We are a small but mighty group of people who strive to stay curious and seek out new ideas and better processes. We genuinely care about our clients, our work, our team, and our community. We count ourselves lucky to work with dedicated people who offer their best efforts and skills for the common good.

OUR CULTURE
What Drives Us
Work hard. Be honest. Do good.
These values drive our work every day. We take the time to get to know our clients—your voice, needs, and audience. We want to understand your passion, suss out your messaging, and then help you elevate it. We support and empower our clients to be confident in managing their brands and websites—because we genuinely care about your success.
Great design is simple, beautiful, and accessible.
We believe good design is a purpose-driving conscious effort to solve problems and connect real people to something that moves them. Creative work is a process of research, brainstorms, iteration, and refinement; often it’s never really done but it’s the intentional effort and timely evolution that meet the needs of that moment.
We take structure, usability, and accessibility seriously. We have a personal approach—no templates, no chatbots, or other outsourced junk that separates us from building relationships directly with our clients.
Better websites build a better community.
There are endless sizes and types of organizations, and we are in our sweet spot when we’re working with nonprofits and local entrepreneurs in Utah and beyond. We help refine communication and messaging so clients can connect with their audiences in a meaningful way.
We get excited about doing good things in our community, and we’re fans of so many others in our community who feel that way, too. We work hard to provide quality services and support so that clients can focus on what they are good at and make our world just a little bit better
Designing for Good (and Fun)
Living and working in an ever-evolving Salt Lake City allows us to be surrounded a community that truly thrives when its everyone pitches in to make it better. Inspired by many others who’ve come before us, we have several projects that we have created to contribute to what we think makes SLC a great place to live:
- Make Your Own Luck
The key to our work and our personal happiness is our community. We know networking events can be the thing that we all hate, but the truth is, sometimes being in person makes magic happen, so Third Sun is hosting this bi-monthly event for clients, friends, and new friends! - Utah Ale Trail
A never-ending quest to find a great place to hang out with great people, showcasing Utah’s eclectic breweries and burgeoning beer scene. We host seasonal events like the Fall Crawl with passports and prizes, because we love an excuse to raise a glass with friends!
