A little About Us

Why we do what we do!


We believe pain is not normal. 

We believe movement is the key to staying happy, healthy, and pain free.

We believe performance can be improved by making changes on the most basic/simple level. We do this through adjusting, lengthening, strengthening, and stretching.

We provide chiropractic care that goes above and beyond your normal healthcare experience.  At Spangler Chiropractic our goal is to significantly improve the function of every patient that comes into our office.

Meet Dr. Logan


Dr. Logan Spangler grew up in a small town of Kansas with his four siblings, where he was involved in his community, athletics, and 4-H. Despite his love for the Nebraska Huskers, he stayed close to home and did his undergraduate studies at Kansas State University. While attending school year round, he also worked full time in a popular BBQ restaurant where he met his now wife, Shari. Married in August 2009, they moved the day after their wedding to Dallas where he could continue his dream of becoming a Doctor of Chiropractic. His inspiration came from his uncle who also graduated from Parker University, one of the top schools in the nation. During his time at Parker University, he found neurology intriguing and took extra courses to get his Certification in Chiropractic Clinical Neurology (CCCN).  Dr. Logan is Titleist Performance Institute TPI certified.

Dr. Logan and his wife Shari are the proud parents of two wonderful little children.  Corey an active little boy who keeps them both on their toes and Shyann a beautiful baby girl who loves to watch her big brother's shenanigans.

Dr. Logan stays active by exercising, playing slow pitch softball, and reliving the glory days on the flag football field. He loves animals and owns two dogs, which he enjoys taking to the dog park or playing fetch. He is also an active member of his church and volunteers regularly. 

Meet Dr. Cas


Dr. Cas Spangler grew up in small town Kansas in a family of seven, where there never seemed to be a dull moment.  Early on in his life he developed a burning passion for sports, spending much of his childhood competing locally and across the state/nation in wrestling, track, and football events.  He continued this passion into college where he earned a scholarship to play football for Hutchinson CC, eventually transferring to Kansas State to finish out his undergraduate requirements in Kinesiology.  

   While attending Kansas State he was introduced a beautiful woman named Taylor.  As they grew closer together, Cas quickly learned that he wanted to spent the rest of his days with her.  He was lucky enough to convince Taylor to move down with him to Dallas and they were soon-to-be married.

    While in Dallas, Cas attended one of the top schools in the country, Parker University, where he earned his Doctorate of Chiropractic. 

    Currently Dr. Cas and his wife live in The Colony.  They have two pets (which they treat more like children).  Anelle, the 90lb Rottweiler and Lola, the anti-social cat.  Dr. Cas' passion for sports has not dwindled over the years.  He regularly participates in flag football, pick-up basketball, kickball, and any other leagues he can find in order to keep himself active.

Brief initial Paperwork

Upon entering the office, we have some brief paperwork for you to fill out. This will be accomplished on an iPad and will provide us with general information about yourself and your condition.

Consultation with Dr. Spangler

Once the paperwork has been completed, you will have a consultation with Dr. Spangler to discuss your health-related problems, concerns, as well as potential treatment options.

Same Day Treatment

In order to determine what your actual problem is, Dr. Spangler will ask you various questions related to your condition. Next, a number of specialized tests will be performed to determine which tissues are affected and to what extent.  This will allow him to get to the root of the problem and work simultaneously on the discomfort and the cause of the discomfort.Once finished with the examination and all appropriate studies, patients will generally be provided with their first treatment. This may include spinal adjustments, therapeutic exercises, soft tissue therapies, and/or support taping depending on what Dr. Spangler deemed necessary from the examination.

Take Home Instructions

Prior to leaving, patients will be given instructions on certain activities or procedures to be conducted at home. This may include ice or heat application instructions, avoidance of certain activities or positions, as well as home exercises and/or stretches.

Schedule Follow Up Appointments

You will be given a convenient appointment time for your follow-up visits. Generally speaking, patients are seen within 1-2 days.

Jodi's Testimonial

We want to find the root of this issue and help you live your healthiest life!  Jodi had an anatomically short leg that we help discover and correct (with a lift and stability exercises) to allow her to live a more active life!


Dr. Logan holds his Titleist Performance Institute (TPI) certification. The TPI certification is designed to overcome and eliminate any physical restrictions that may be limiting a golfer’s maximum potential. As a TPI professional Dr. Logan is versed in the latest golf-specific health, nutrition, and fitness.  This entails the most common golf swing characteristic, physical screening techniques, prescription exercises, and finally to the most recent research and development in the field of golf swing analysis.  The TPI 16 point movement screen utilizes a scoring system that documents movement patterns that are key to normal function.  By using the TPI screen, patterns are identified that show functional limitations and asymmetries in the athletes.  These limitations can reduce the effects of:

Functional training: Functional training is needed to produce speed and power so players are able to add distance to their shots.

Physical conditioning: Conditioning plays a roll in late round fatigue and injury prevention especially to the low back.

 Body awareness: Body awareness affects the ability to have consistent ball striking capabilities, which ultimately affects accuracy and your scorecard.  

Knowing these limitations allows Dr. Logan to produce the most beneficial treatment plan with corrective exercises to restore biomechanically sound movement patterns.  The benefit of this goes beyond just golfers but athletes of all sports.

Stages of care


Relief/Stability Care

Relief care is the first stage of care for most patients. The primary goal during this initial stage is to provide the individual with symptomatic relief. Treatments focus on specific techniques and soft tissue therapies that quickly and effectively reduce pain, inflammation and stiffness. This will allow the majority of individuals to continue their daily activities with little to no interruption. Patients are encouraged to stay mobile and functional so long as there is not a risk of further injury or tissue damage.  At the end of this care we slowly start to add stability exercises and activities that will boost our patients into the next phase of care.


Function/Performance Care

The second stage of care consists of correcting the problem that contributed to the condition.  This is the functional and performance stage of care. This stage is vitally important to ensure that we correct the issues to allow every patient to function properly in their daily lives.  It is extremely important that our patients comply with and follow the instructions given by the doctor during this stage of care.  Functional and Performance care will require in office exercising, one on one with the doctor or therapist, which is specific to each individual condition.  This will also require "homework" exercises that will be prescribed by the doctor.  When we see a patient with pain it is vital to understand that pain is the last to come and is the first to go with chiropractic.  Maintaining proper biomechanical function and performance keeps the pain away long term!


Maintenance Care

Once we have decreased the pain/inflammation/stiffness, added stability, and reached a point of proper function and superior performance we want to keep you that way!  For some this might mean seeing you once per year, for others this may mean once per month or once every other week. This is the stage of care we strive for all our patients to reach as quickly as possible.  Chiropractic maintenance is like proper hygiene or brushing your teeth, it keeps what we have healthy, healthy.
