Dr. Darby Thomas

chiropractor Lakewood, CODr. Darby Thomas is a chiropractor in Lakewood CO who serves patients in both Lakewood, Belmar and the surrounding areas.

Since childhood, Dr. Darby has known that she wanted to be a doctor and care for others. While attending Clemson University as a biological sciences major, she was awakened to the problems in today’s sick care model, and decided to rethink what kind of doctor she wanted to be. She was fortunate to live close to Sherman College of Straight Chiropractic and grow up in a family under chiropractic care. After working in a local chiropractic office, she knew that joining the greatest profession in the world was the right step and has never looked back. Dr. Darby is thrilled to have the opportunity to live in Colorado and provide safe, effective Lakewood chiropractic care to the community.

Dr. Darby seeks to improve her chiropractic patients’ health and wellness in all areas of their lives. Dr. Darby likes to treat the “whole person” in her work as a chiropractor, which means looking for the underlying causes of disease, discomfort, and pain, which usually arise from imbalances in the spinal column. Under Dr. Darby’s supervision and care, patients report less pain and higher functioning in all areas of their lives.

Dr. Darby’s mission as a chiropractor here is to live at 100% in both health and life. She will constantly enlighten and challenge you to pursue your health goals so that you will achieve abundant health for you and your family.

How We Help Our Patients

At 100% Chiropractic in Lakewood, we believe it means giving your body the opportunity to function optimally, as pain-free as possible. With all systems go, you’re able to work, ski, hike, play with your kids, enjoy a baseball game, and do anything else you love to do. Optimal functioning starts with a healthy spine.

100% Chiropractic in Belmar-Lakewood, CO is committed to you and your family. A healthy spine starts with routine wellness visits to help prevent pain and symptoms before they begin. However, various life events and conditions can have you feeling less than 100%. We help our patients find relief from these conditions and more:

  • Migraines and other headaches
  • Back and neck pain
  • Joint pain
  • Allergies
  • Asthma
  • Prenatal discomfort
  • Gastrointestinal issues
  • Insomnia

At our Lakewood/Belmar chiropractic office, we offer a wide range of expertise to provide you and your family with optimal care and help with any pain you are experiencing. To best serve you, we offer a variety of specific services to meet your needs:

  • Corrective Care: Subluxations as a result of accidents, patterns of moving, or too much sitting can leave the spine in a less-than-ideal alignment and can cause a lot of pain. Our mission is to gently restore the spine’s natural curves using X-Rays to help us monitor your progress so we can offer specific, efficient care.
  • Prenatal Care: Pregnancy introduces new demands on the spine, often resulting in discomfort throughout the body. Chiropractic care can help keep the spine healthy throughout your pregnancy while decreasing discomfort and helping you prepare for labor.
  • Pediatric Care: During birth, extreme forces may be applied to the baby’s spine, and it is during this process that babies often experience their first spinal subluxations. Babies typically respond quickly to chiropractic treatment, since they haven’t had years of habits ingraining specific patterns into their bodies.
  • Massage Therapy: Chiropractic and massage are completely different therapies, but they go hand-in-hand. A good massage can help relax the muscles that hold the body in specific patterns; massages also promote good circulation and the healing of damaged tissue.

Why 100% Chiropractic?

Health is more than merely the absence of disease and pain. Health is about feeling your best–100%–every day. We are happy to work with our chiropractic patients to ease pain and symptoms, as that is the first step to finding your own personal high level of well-being, but beyond that our mission is helping you live at 100% by becoming your partner in long-term health.

As we build an ongoing relationship devoted to your health, the treatment plan evolves as you do. You and your entire family are always welcome in our Lakewood office. We are glad to answer your questions and help you learn more about what a healthy spine means for your quality of life.

I have been getting taken care of mentally, emotionally, and physically as a staff member here but also as a friend and I know we offer the same with everyone who walks into our office. Our patients become our family and I cannot wait to meet you!

It was through him that I first learned about chiropractic care and continued wellness. Ever since I have always been amazed by the positive effects of spinal adjustment both on the mind and the body. Working at 100%, I will be experiencing my very own first set of life-changing adjustments, which I am very excited about. The inviting atmosphere and friendly staff feel more like a family than a business. I am looking forward to being a part of such an awesome company!

“Dr. Darby at 100% Chiropractic in Lakewood has made a world of difference in my quality of life. Before seeing her, 95% of my sick time from work was taken up by migraine pain. I’m thrilled to say that I haven’t used a single day of sick time this year! I went from having 6-10 migraines a month to maybe 1. I’m so happy with my decision to come here.” – Jamie

“15 years ago I was hit in the face with a softball. I was initially treated with braces, muscle relaxers, topical ointments and mouth guards. Nothing worked! I was told surgically breaking and wiring my jaw shut was my only option. 15 years later I moved to Colorado and the stress caused me to have so much TMJ pain I was unable to eat and ended up on a protein water diet. Since I started working with Dr. Darby as my chiropractor at 100% in Lakewood, I can eat meats, breads and my pain has gone down to almost none at all. I sleep through the night and have more energy when I wake up.” – Melissa
