Dr. Cody Davis


  • Palmer Alumni

  • Pi Kappa Chi Professional Chiropractic Fraternity

  • Integrity Verified Doctor

Dr. Cody Davis "Doc" began his schooling at Woodbury Central High School and

continued his education by graduating from Briar Cliff University in Sioux City, IA

with a Bachelors Degree in Exercise Science. Dr. Davis’ emphasis on Athletic Training

led him to work with a multitude of athletes, including an internship with CNOS Dakota Dunes.

He followed by earning his professional degree from Palmer College of Chiropractic in Davenport, IA, graduating in 2013.

As a collegiate athlete, Dr. Davis experienced the benefits of chiropractic care for decreasing injuries and optimal function. After graduation, Dr. Davis was hired as an Associate Doctor with Active Life Chiropractic in Nashville, TN where he treated patients for almost 4 years. The practice grew substantially, but more importantly, the patients benefiting from his skill continued to grow and see improvement through each treatment. He decided in 2016 he wanted to bring his experience and knowledge to the surrounding communities of Siouxland and open his own clinic in March of 2017.​

He has been part of numerous volunteer programs including the Davenport Red Cross Rehabilitation Clinic, Big Brother Big Sisters of Sioux City, also through the Mt. Juliet Help Center and Avalyn Shaye Foundation.

Dr. Davis also offers a unique aspect to working with children. Early in his career, Dr. Davis trained under Dr. Cherie Marriott, D.I.C.C.P. Board Certified Pediatric Chiropractor. “Children hold potential that only educated minds can understand for their superior health.”

Here in Sioux City, Dr. Davis has been a member of the Siouxland Chamber of Commerce since opening.

His focus is total body health and wellness without the use of surgery or medication. His goal is to reach as many spines as divinely possible to educate how to stay healthy through chiropractic care, nutrition, and injury prevention. His experience, technique, and skill will ensure that your spine will undergo proper analysis and treatment to induce healing.

If you start talking golf or ISU sports, you'll quickly become best friends with Doc!

Jamie Vess

Clinic Manager

Jamie works alongside Dr. Davis in the practice operations as the Clinic Manager.

She handles the 'behind the scenes' flow of the clinic as well as working with

patients one on one with nutrition and lifestyle guidance through her

health store, and where you will see her the most, Next to Nature.

Jamie is extremely passionate about helping people become the best

they can be in any aspect of life.

A little background, while in Nashville, Jamie spent some of her time working for

an attorney. Further learning business law and real estate management, she quickly

found an interest and appreciation for those areas of her work. She then went on to

work as an Executive Assistant to two global power-house sales consultants. Handling

everything from client management, travel and scheduling, to all things business operations, marketing and growth. Jamie realized just how much she was capable of doing if she just put her mind and efforts to what she believed in. Prior to this she was a published music photographer in the Music City for many years and explored the world of painting and woodwork for fun.


Her desire for life, creativity, and helping others has led her to her most exciting career and lifelong commitment with her best friend in Iowa.  Dr. Davis and Jamie got engaged in August of 2017 and welcomed their thriving baby boy, Arlo Nash in September 2018. They reside in Kingsley, IA with their 3 dogs, Criket, a Mini Schnauzer, Chip, a Giant Schnauzer, and Cookie Cruz, a Newfoundland, who you will see around the clinic any time Jamie is in.

Arlo Nash

Dr. Davis & Jamie's Greatest Accomplishment

Arlo will graciously bless patients with his sweet smile and love for chit chat on occasion. He helps Dr. Davis at the adjusting table, occasionally wiping down, occasionally pressing the drop lever, and occasionally gets really excited about just anything and runs around the clinic. He loves to be outside, play in the dirt with his pups, play golf with Daddy, and paint with Momma. He is mostly with his buddy, Shan, during the day at home or another floor within our office.
