There are over 70,000 Doctors of Chiropractic in the United States that treat an estimated 35 million Americans each year. Chiropractic Physicians are portal of entry providers (no referral required from another doctor) that are trained and licensed to examine, diagnose, and treat various conditions without using drugs or surgery.

Though chiropractors are most known for working with their hands, they are trained and licensed to provide other treatments like exercise and rehabilitation, nutrition therapy, lifestyle counseling, and much more. Because of the wide variety of effective tools, chiropractic is an ideal service for those looking to recover from soft tissue (spinal disc, muscle, tendon, ligament) and joint injuries, improve athletic performance, prevent future injury and pain, and much more.

Your appointment at St. Johns Chiropractic & Performance starts with us taking the time to get to know you, hear your story, and understand what your goals are. We then perform a detailed examination to pinpoint the source of the problem. After we have discussed the diagnosis with you, we will combine your goals with our clinical recommendations to determine the best route to getting you where you want to be!

Dr. Speer can order advanced diagnostic tools such as imaging and blood analysis when clinically necessary. He also can refer you to other healthcare providers if after the examination he feels that you would be in better hands with another healthcare provider.

In a study that followed 1,885 Washington State workers, 42.7% of workers who saw a surgeon initially for their low back pain ended up having surgery. While those who first saw a Chiropractor for their low back pain only ended up having surgery 1.5% of the time. – Spine (2012)

Low back pain patients who saw a chiropractor as their initial provider had 90% decreased odds for opioid use. – BMJ Open (2019)

 According to this systematic review of the literature, chiropractic patients had a 64% lower chance of getting an opioid prescription compared to those who were not chiropractic patients. – Pain Medicine (2019)

Joint Manipulation

Joint manipulation (also called an “adjustment”) occurs when the clinician takes a joint to its’ end range of motion and delivers an impulse. This impulse often creates more motion, decreases pain in the area, and normalizes the local muscle activity. Adjustments most commonly occur in the joints of the spine, but also in various extremities such as the foot or shoulder.

Dr. Speer has spent hundreds of hours learning anatomy, biomechanics, and the art of adjusting patients along with many more hours of practicing the skill of adjusting patients. He had about a hundred hours of continuing education seminars outside of school dedicated solely to learning when, how, and why to adjust patients. He learned directly under and even interned under some of the top manipulation experts in the world. He also spent about 2 years teaching the anatomy, biomechanics, research, and technique of adjusting to the fellow students at Logan University.


While it has been known for a while that the chiropractic adjustment has made patients feel better, there is more and more proof of this coming out in the scientific literature:

Spinal manipulation was proven to be significantly more effective than medication in both the short term and long term for neck pain. – Annals of Internal Medicine (2012)

In patients with long term neck pain, spinal manipulation combined with a home exercise program was proven to be less costly and more clinically effective than a home exercise program alone or a home exercise program combined with supervised rehab exercise. – Spine (2016)

In patients with low back pain, manual thrust spinal manipulation provided significantly greater reductions in self-reported pain and disability than usual medical care when evaluated 4 weeks after the treatments were given. – Spine (2015)

In patients with short to moderate term low back pain, conservative therapies such as spinal manipulation should be considered before moving onto pharmacologic treatment. Patients with long term low back pain should initially chose conservative treatments like exercise or spinal manipulation. – American College of Physicians (2017)

This study compared one session of thoracic (mid-back) spinal manipulation to one session of sham treatment in patients with cervical radiculopathy (nerve symptoms in the neck). Patients who received manipulation had decreased pain and disability and had increased neck range of motion and neck muscle endurance compared to the sham group both immediately after treatment and at short term follow up. – Journal of Orthopaedic & Sports Physical Therapy (2019)

Manipulation of the foot and ankle combined with cross friction massage of the foot and lower leg significantly reduced pain and increased ankle range of motion in patients with plantar fasciitis. – Health SA (2019)

Exercise Rehabilitation

 Rehab or Therapeutic Exercise may be the most research supported intervention for joint and muscle pain and injuries; and has especially impressive results when combined with manipulation. Through his many hours spent learning biomechanics and several rehabilitation techniques, Dr. Speer can use exercise rehab to get you out of pain in a timely manner and then make your body more resilient to prevent future episodes of pain and injury. Combining in-office exercise with prescribed at-home exercise, is an effective way to help you achieve your health goals and make your body even stronger and more mobile than when you first got injured.

A multimodal approach including spinal manipulation, exercise, and self-management advice is an effective strategy for both short and long term back pain and back pain with leg pain. – Journal of Manipulative & Physiological Therapeutics (2018)

Low back pain patients that were categorized as having low back stiffness by a clinician had greater benefit from spinal manipulation; low back pain patients that were categorized as having low back hypermobility had greater benefit from a stabilization exercise program. – Archives of Physical Medicine and Rehabilitation (2005)

This review of the literature showed that exercise, including resistance training, stabilization exercises, and motor control exercises, resulted in decreased pain levels, increased physical function, and increased muscle endurance in patients with low back pain. – British Journal of Sports Medicine (2019)

In a study of 54 patients with neck pain, those that completed a neck muscle exercise program had decreased pain and physical limitations and increased neck muscle strength, and improved posture compared to the control group. – Journal of Pain Research (2019)

In a study with 84 plantar fasciitis patients, both stretching and strengthening exercises were shown to significantly reduce pain and improve walking motion. – Annals of Rehabilitation Medicine (2019)

Manual Therapy

Aside from their expertise in manipulation, Chiropractors are well versed in other manual therapy techniques such as soft tissue work on muscles and tendons, hands-on stretching, relaxation techniques, kinesio-taping, and cupping. Manual therapy is very effective when recovering from sports injuries, delayed-onset muscle soreness, and general aches and pains. Along with many of the common back, neck, shoulder, and hip complaints that Chiropractors often deal with, manual therapy also works especially well in conditions such as plantar fasciitis, temporo-mandibular joint dysfunction (TMJD), and tension headaches.

In a study of 33 patients with shoulder impingement syndrome, the group that received supervised exercise along with manual therapy had significantly better outcomes than the control group that simply received advice from a physician. The group had greater decreases in pain and higher improvement in function than the control group. – Journal of Manual & Manipulative Therapy (2008)

18 patients were divided into one group that received manual therapy on their hips and another group that received a placebo treatment. Patients who had manual therapy performed on their hips, had an 8% increase in hip muscle strength afterwards. The placebo group had a 4% decrease in strength after their sham treatment. – Journal of Manual & Manipulative Therapy (2021)

In a literature review determining the best treatments for plantar fasciitismanual therapy was clearly associated with reduced pain and improved function in patients. It is recommended to use manipulationexercisestretching, and other manual therapy techniques to treat plantar fasciitis. – Journal of Manual & Manipulative Therapy (2018)

In this literature review, it was found that manual therapy decreased pain by activating pain-relieving chemicals in our body. It was also found that muscle tone, endurance, and strength were all normalized after manual therapy. – Spine (2016)

Nutritional Therapy

What we put into our bodies has a far greater impact on our health than most realize. Our nutrition impacts our pain levels, the structure of our joints and muscles, our energy levels throughout our day and our workouts, and much more. The problem is, there are many confusing and conflicting messages about what foods, drinks, and supplements are healthy to consume and what products we should stay away from. Dr. Speer realizes how important nutrition is to your current and long-term health, but also is aware of the confusion and difficulty when attempting to initiate diet changes.

At St. Johns Chiropractic & Performance, we do not believe in fad diets, but we do believe in long-term sustainable solutions to help you meet your nutrition and health goals. We seek to help those trying to lose weight, athletes who seek to use nutrition to improve performance, and people who simply just want to feel better. We will meet you where you are and together, we will form a plan that works for your timeline and will help you achieve your specific goals. We will equip and empower you with the education and tools that you need so you will no longer be confused by the conflicting and “trendy” information about nutrition.

A typical Western (American) diet is associated with chronic inflammation, chronic pain, and higher pain intensities. Healthy dietary changes away from the Western diet have shown to have pain-relieving effects. – Journal of Clinical Medicine (2020)

While nutrient deficiencies increase chances of pain, switching to an anti-inflammatory diet that ensures adequate vitamin intake increases chances for reducing pain and joint stiffness. Diet evaluation should always be part of a medical examination for chronic pain. – Pain (2012)

People with an elevated Body Mass Index, have a higher risk for developing muscle and joint pain, headaches, chronic low back pain, osteoarthritis, tendonitis, and abdominal pain. – Chiropractic & Manual Therapies (2013)

Athletes were found to have 6% faster race times when consuming an anti-inflammatory diet on the days leading up to competition versus when they eat a Western (American) diet. – Journal of American College of Nutrition (2019)

“I have never seen anyone be the best version of themselves by eating a crappy diet.” – Mark Hyman, MD, Director of Functional Medicine at the Cleveland Clinic

Lifestyle Management

 At St. Johns Chiropractic & Performance, we strive to be healthy in all aspects of our lives, from nutrition to exercise to our relationships and social habits, and much more. One of the most impactful interventions in the health field is lifestyle management and we would not be doing our due diligence if we did not at least offer this service to our patients. It also it happens to be something we are very passionate about.

Every day, the thoughts that you think, the food that you eat, your level of activity, and many other social and environmental factors all combine to give you your current status of health. These factors not only impact your well-being and performance in the short term, but they also determine how you express your genetic potential for health and/or disease in long term. Research over the last several years even shows that you pass this potential along to your future generations!

Lifestyle practices including poor nutrition and diet, unhealthy body weight, inactivity, poor sleep, smoking, and poorly managed mental stress, can all independently or in combination create muscle and joints aches and pains and limit physical capacity. – BMC Musculoskeletal Disorders (2015)

Lifestyle behaviors such as poor sleep habits, abdominal obesity, lack of physical activity and a sedentary lifestyle, smoking, negative stress, poor self-efficacy, and many more factors put you at a greater risk for expressing pain physically. Adopting healthy lifestyle behaviors is a main intervention to decreasing this risk. – Physical Therapy (2018)

Chronic diseases such as diabetes, heart disease, and chronic pain have been associated with insufficient physical activity, poor diet, and abdominal obesity. This review of the literature showed that lifestyle behavior interventions significantly increased physical activity while significantly reducing body mass and waist circumference. – Journal of Behavioral Nutrition and Physical Activity (2021)

The diet we consume one of key modifiable factors that can positively or negatively alter the genes we express. With this knowledge, we may be able to alter our risk for metabolic disturbances, like diabetes, hypertension, and heart disease. What we eat not only effects our own genes, but the genes of our offspring. – International Journal of Molecular Sciences (2020)

A collegiate basketball team underwent a study related to their sleep and performance during their season. Over a 5-week period the players increased their nightly sleep total. Compared to the pre-testing done before the sleep increase, the post-tests showed the players had improved mental and physical well-being, faster reaction times, decreased fatigue, improved sprint times, and 9% better shooting accuracy. – SLEEP (2011)

Sleep loss disrupts your metabolism, increases your risk for obesity, and alters the expression of your genes and hormones. Long-term sleep deprivation side-effects can include heart disease, high blood pressure, and impaired learning and memory. – Frontiers in Neural Circuits (2018)
