Meet the Doctor

Hi. I am Dr. James Johnson D. C. I grew up in Douglas, Wyoming and attended the University of Wyoming before transferring to Palmer College of Chiropractic in Iowa, where I completed my Bachelors of Science as well as Doctor of Chiropractic Degrees. I moved to the beautiful town of Buffalo and opened up my chiropractic office in 2001. In the fall of 2016, I incorporated BrainCore Neurofeedback into the practice as another tool to help patients realize their optimal health.

I want to share chiropractic and neurofeedback so people can realize their full potential and live life to the fullest with less dependence on prescription medication and surgery.

Meet Our Staff

Our staff has been helping people live pain-free since our clinic opened in February of 2001. The staff is experienced and committed to promoting health.


Jamie Sayer

Hi, my name is Jamie Sayer. I am married with one son. My husband and I were born and raised in the Buffalo and Sheridan area. We enjoy all things outdoors and Wyoming.

I first became a patient at Johnson Chiropractic in 2013. I had not been to a chiropractor before and did not know what to expect. I quickly became a strong supporter of chiropractic and brought my husband and son in to resolve their issues and we are all now on regular maintenance.

I became part of the Johnson Chiropractic Team in 2015. In 2016, I attended training to become a BrainCore Neurofeedback Therapy Technician and have been performing  BrainCore Neurofeedback Therapy Sessions since the fall of 2016. 



Treena Wagner

Hi! My name is Treena Wagner and I was born and raised in Montana. I graduated High School in Roberts, MT and went on to graduate from Montana State University with a degree in Biology. After graduating, I got married and moved here to Buffalo, WY. I've enjoyed living in Buffalo for the last 20+ years with my husband Todd, and my kids, Miranda and Nate.

I have been a patient of Dr. Johnson's for several years and joined the Johnson Chiropractic Team in April 2017. I only wish I would have started coming earlier when my kids were young! The benefits of chiropractic care are enormous and have helped me greatly.
