Sladjana MCcord, Operations Manager

Sladjana McCord

As the Operations Manager, Sladjana is responsible for all aspects of making sure the office runs smoothly and effectively. Sladjana combines a unique passion for content creation, marketing expertise and event planning to meet the marketing goals at our office. She works with local businesses, large and small, setting up Well 10 talks (10 minutes health talks), spinal screenings by appointment and many other wellness education events.  She thrives on igniting team spirit while encouraging team goals and personal development to steer the team towards success!

In addition, Sladjana and her husband Tony have an adorable one year old girl and two rather spoiled pups. In their free time, they enjoy traveling to whatever destination awaits, which usually ends up being somewhere in the South Dakota countryside or along any number of rivers and lakes. They are also live music fans (especially country music), love traveling to where our feet can touch the ocean and spend a lot of time surrounded by family and friends (good food and cold drinks are always a bonus). Otherwise camping, planning parties/events and cheering on the VIKINGS occupies most of Sladjana’s time.
