Why? To help more people spend more time outside.

More often. More ways.

More reasons. More places.

More.

Because we know we need it, and we know it’s hard.

SUM makes outside easy - for you, for everyone.

What SUM Does

SUM curates and leads a wide variety of group experiences - staff retreats, wellness outings, field trips, team culture sessions, rejuvenation days and more - all outside and close to Chicago. 

Work team? Social organization? Leadership cohort? Youth group? Whoever you are, SUM works with you to understand your needs and aspirations. We then customize an experience - or set of experiences - around your unique aspirations.

SUM brings the benefits of time spent outside - focus, calm, insight, and connection - to people and groups who need it.

Why Outside?

SUM knows everyone can benefit physically, emotionally, mentally, and spiritually from time spent outside - as long as it’s easy, safe, and welcoming. That takes work.

There are many reasons people don’t spend more time outside. Modern life tells us there is too much work, not enough time, outside is for the weekend, and so on. Some are constructs of societal shifts toward isolation. And some are the result of barriers, exclusion and discrimination.

SUM is working to change this. SUM is working to ensure that our core premise - everyone + outside - means just that.

SUM’s our name and our philosophy. It means everyone + outside. It means more people + place + moment. SUM means the total positive impact of all that - the sum. 

SUM is a registered 501(c)3, founded in 2022. Our founders came together around the simple notion that it should be easier for more people to reap the benefits of time spent outside. Then we founded SUM to do the hard work of making that easy notion a reality.

As of June 2026, SUM has been honored to lead restorative experiences outside for 3,200 people and counting… and we’re just getting started!
