Learn Who We Are

  • Dr.
    Jack Crocker

    Hi! My name is Dr. Jack Crocker. I was born and raised in Lebanon, Missouri. After graduation I moved to Springfield, Missouri and worked for a short time, until I was drafted into the U.S. Army. After my tour of duty I knew I wanted to do something to help other people. So, I went back to college and obtained my undergraduate degree in radiology. This enabled me to work in different hospitals while I finished my pre-med degree. With all the education I received, and the experiences I had in the hospitals, I really felt that there had to be another way to help others get and stay well, without the use of medicines or surgery. That is when I decided to go to Chiropractic college. I had been helped by Chiropractic when I was very young with headaches and I felt this was a great way to help others like it helped me. I thank the Lord every day for placing me here. I have seen so many people's lives changed through Chiropractic and the work we do here. If you are reading this I hope you give us a call, so we may have the privilege to help you get on the road to better health.

Reviews By Our Satisfied Patients

  • "I was told that there was no hope, just pain pills. Going to Dr. Jack WAS my last hope. I could not take a shower without pain, could not play with my grandson, or go to stores. Before I would just sit in my chair with no movement at all, it made life not worth living at all. I just wanted to lay around and not ever get up. Treatment took 1 to 2 months before I got relief but now I can now go fishing, play with my grandson, clean up my workshop, and get things done around the house."
