Our Team

  • SladjanaMcCord
    Sladjana McCord
    Operations Manager

    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 two adorable children.  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.

    Katie Pulliam
    Chiropractic Assistant

    Katie is enthusiastic about patient care and one on one interactions with all our patients. Katie helps assists with scheduling, billing, and any patient needs. When Katie isn't working, she loves to ride motorcycles, camp and fish, and spend quality time with family and friends. When Katie was asked what her sole purpose was, we knew she was a fit for OFC, as her answer was 'to improve the lives of others'. Katie is from Peoria IL and graduated in 2008. She is engaged to be married with two beautiful daughters. 

    I was introduced to Chiropractic in 2022. Before starting care, I was on medication for anxiety, depression, high blood pressure, and ADHD. I am currently on no medication and my health is better than it has ever been. Through chiropractic I was also introduced to the benefits of mediation and have seen a positive outcome in not just myself but my children as well. With continued education and my personal improvement, my view on health has completely changed. I have watched Dr. Ben enhance the lives of hundreds of individuals. Being part of that change has given me an immense amount of purpose and my only regret is that I didn’t find chiropractic sooner.

    Personal Quote: 

    If you don’t like something change it, if you can’t change it change your attitude.

    Tomorrow isn’t promised; do what you love today.
