Our Values

One Team. One Dream.

We all share one dream, united and driven. We're one team, because we respect, trust and care for each other. We're on a mission to change the world for good, and we'll only achieve a goal as big as this together. That's why when we ask for help, we know we'll get it.

We fail together. We learn together. we succeed together.

One Team. One Dream.

We Deliver

Our word is our reputation. We live or die by it. If we say we'll be there, we'll be there. On time and committed. We go above and beyond to deliver to our clients, our members and to each other. We take employers' most precious resources - their people - and deliver them back, better than ever, ready to perform at their best. Its a huge privilege and an even bigger responsibility.

When it comes to what we do, how we do it and how we treat each other - others make promises, we deliver.

We Deliver

Insatiable Curiosity

We don't wait to be told - we're hungry to find a better way to get the job done. We share our ideas, however big or small, because we know that even small changes can achieve big results. We ask the hard questions to find the right answers. By finding the 'why', then we discover the 'how', even if that means turning everything on its head, upside down and inside out.

If there's a better, faster, simpler way to make things happen, we'll find it.

Insatiable Curiosity

Live it and Breathe It

To be authentic and genuine in who we are and what we do, we need to live and breathe it. We need to show our clients and members what a culture of health and engagement really looks like. And it starts with you. Organize that walking meeting. Head to the gym at lunch. Sleep well, eat well. It's what gives you the energy and clarity of mind to get the best out of every day.

Because when we 'do', they follow. Our clients, our friends, and our families. Lead the revolution.

Live it and Breathe It

Seriously Fun

If changing the world is our destination, then getting there is half the fun. We love the serious work of improving the health and cultures of our clients, but if we can't have fun along the way, we're missing our own point. We put in the hard work, and we celebrate the wins - big and small.

Laughter is the music that fills the office and keeps the dance floor buzzing. And that's why our clients and members want to join the party.

Seriously Fun

Saddle Up

We thrive when we're challenged and we're not afraid to take risks. Because courage is being scared to death but saddling up anyway. Sometimes its the tough conversations with our colleagues and our clients that get the best results. We're straight talkers - considered and considerate.

We're bold giving feedback, and brave accepting it, up and down the line.

Saddle Up

This work involves the application of network science and mathematical models to understand the dynamics of health in longitudinally evolving networks. This body of work has also engaged the spread of emotional states such as happiness, depression, and loneliness within social networks. Other recent work has used experiments to examine the spread of altruism (here and here) in social networks and the genetic (here and here) and evolutionary determinants of social network structure.

This book has been translated into nearly 20 foreign languages, and it has been widely reviewed. Dr. Christakis’ past work was focused on topics related to end-of-life care, such as hospice care, widowhood and caregiver burden, ICU decision-making, and the role of prognostication in medicine (about which he has written three books, including clinical textbooks).
