Dr. Cody Davis


  • Palmer Alumni

  • Pi Kappa Chi Professional Chiropractic Fraternity

  • Integrity Verified Doctor

Dr. Cody Davis 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.


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 brings his experience and knowledge to the surrounding communities of Siouxland.

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.” His experience, technique, and skill will ensure that your spine will undergo proper analysis and treatment to induce healing.


Here in Sioux City, Dr. Davis has been a member of the Siouxland Chamber of Commerce since opening in 2017. 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. 

Jamie Vess

Office Manager

Jamie works alongside Dr. Davis in the practice operations as the Office 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 in her

health store, 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 photographer in the Music City for many years and explored the world of painting and woodwork, which is now her 'downtime / creative space' work.


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.

Quality Control Manager

"Jack of all trades" may be a better term for this friendly face you might have seen around before! “Jen-Jen” has been with Doctor Davis and Jamie since January of 2020 when she started hanging out with Arlo Nash on the daily, and she did that for the remainder of the year. Once December rolled around, Jenna ended her fall sophomore semester and decided to go through a substitute teaching course to come closer to her goal of teaching. Now, Jenna spends her days helping Doc, Jamie, Arlo, and the clinic/store staff with any and everything. You'll see her working alongside Doc a few days a week, giving Jamie time to be in the store. Jenna is a Sioux City native and she is currently studying her bachelor’s degree at Wayne State College in South Sioux, but completed her associate’s degree at WIT and Northeast CC. When not studying or working, she spends her time loving on her pups Lucy, Lily, Laiken or her cat Luna, and hanging with her boyfriend, Matt.

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 on another floor within our office.
