Dr. Katie Harley, D.C.


Hi there! My name is Dr. Katie Harley. I was born, raised, and still reside in Windsor, IL. It is a rural town of 1,200 people and suits this small-town girl’s heart quite nicely. I attended Windsor schools, as did my high school sweetheart, Chris. We’ve been together for 23 years, married since 2006, and have 8-year-old twins, Georgia and Gibson. We love teaching them all about the great outdoors, how to camp, fish, boat, ride side-by-sides and sometimes help the neighbors deliver a baby calf or two.

Higher education led me to bigger cities and experiences. After graduating valedictorian from my high school class, I attended Eastern Illinois University, majoring in Pre-Chiropractic. I was always fascinated with the human body and how it functions. After being rear-ended when I was 16, I experienced my first chiropractic adjustment. I was amazed at how much it helped with my whiplash injury. I transferred to Logan College of Chiropractic (now called Logan University) near St. Louis, MO, and received my BS in Human Biology in 2003 and my Doctor of Chiropractic degree in 2005.

After practicing as an associate for 8 years, it was time to open my own office. Sullivan, IL has been the perfect fit for Harley Chiropractic, LLC since we opened our doors in 2014. We get to help all of the wonderful people in this town and the surrounding communities.

This is not a job for me, it is a passion and my true calling. I am so grateful to get to come to the office and play a small part in the daily miracles I see in my patients as their bodies heal. Thank you to my patients who have allowed me to be part of their healing and wellness journeys.

Chiropractic Assistant

Hi, I am Bobbie! I grew up in a military family, so I moved around a lot as a kid, but Sullivan was always home. I always knew I wanted to raise my children surrounded by family, so after graduating high school in California, I moved back to Sullivan. I am married to an amazing man and a mother to two beautiful daughters of my own and the bonus mom to another beautiful daughter. I love to hang out with my family and friends, spend as much time on the water as possible, and travel any chance I get.

I have worked in healthcare in one capacity or another for over 17 years. I genuinely believe it has always been my calling to help others. With Chiropractic I am now able to do that in a whole new way. I love to be a part of my patient’s success stories, even if it is only to put a smile on their face while they are dealing with pain.

I will be completely honest; I had always thought chiropractic care was only for the spine. Boy was I wrong. Dr. Harley has not only helped me with back pain, but she has also helped with my feet, wrist, neck, shoulder, and even my stomach issues. I am blown away daily as to what all chiropractic can help with. I have witnessed things that can only be described as miracles. I have learned so much from her and look forward to learning so much more. The body is an amazing thing!

I would love to meet all of you and help you feel your absolute best every day!
