About Chiropractic St. Charles, IL

About Us

As your St. Charles chiropractic team, we are committed to delivering the highest level of chiropractic care to each and every patient. Our chiropractic wellness center offers St. Charles community members the opportunity to prevent and treat injuries, relieve pain and improve overall wellness through chiropractic adjustments and therapies.

The initial exam process is a critical part of your treatment at our St. Charles chiropractic office. All new patients undergo a non-invasive exam which includes a thorough health history, two X-rays (if medically necessary), a full chiropractic exam (including range of motion tests) and a doctor’s consultation. The results from your exam are reviewed by our St. Charles chiropractor to determine the best course of treatment for your needs.

Many patients come to us in pain whether it’s back pain, neck pain, sciatica, shoulder or arm pain, joint issues, arthritis, fibromyalgia, headaches, migraines and more, we see it all. If you’re in pain, our highest priority is to relieve this pain as quickly as possible through a therapeutic care plan. Our St. Charles chiropractor will work directly with you to design a care plan consisting of adjustments and therapies to relieve your pain. We have many Chiro One patients whose pain decreases significantly after starting care, and this is our goal for every patient that walks through our doors.

After pain has been relieved, many patients then move onto corrective care. The goal of this stage of care is to correct any structural abnormalities in the spine and improper posture. Patients who complete the corrective stage of care often find that their pain or health condition is permanently improved.

The final stage of care is wellness! Once patients have graduated from both the therapeutic and corrective care stages, they are able to maintain their spinal health and overall well-being through preventative, wellness-based chiropractic care. Our St. Charles chiropractic office is here to serve you. We are looking forward to seeing you in our office soon. Call us or schedule an appointment online today!

St. Charles

Education: Northwestern Health Sciences

Hometown: Larrabee, Iowa

Originally from rural Iowa, Dr. Lacie Drennan is now proud to serve patients and community members as chiropractic director of Chiro One Wellness Center ...of St. Charles.

Dr. Lacie's relationship with chiropractic began at age 15 after a severe car accident that left her with chronic, debilitating migraines. She found herself missing classes and sporting events, plagued by constant nausea and pain. Like many, she embarked on the all-too-common journey of multiple medications. She even had an MD tell her to avoid dairy, chocolate and gluten and maybe her migraines "might go away" in a few years.

Unwilling to suffer any longer, Dr. Lacie went to a chiropractor. Her life was changed forever, relieving pressure and helping her out of pain. She says, "Chiropractic gave me my life back, and I knew after that first adjustment that I wanted to become a chiropractor to help others, so they never had to suffer like I did."

After achieving her bachelors at Buena Vista University, Dr. Lacie earned her doctorate of chiropractic at Northwestern Health Sciences University. While in school, not only was she a Dean's List student, but she was an active member of the Health and Wellness Fitness Club and the Student American Chiropractic Association Sports Council.

After spending a few years post-grad practicing chiropractic in San Diego, Dr. Lacie joined the Chiro One family. In practice, she adores working with athletes, educating patients on improved mobility and function. She's also a member of the American Chiropractic Association.

Dr. Lacie's favorite part of being a chiropractor is helping her patients live their best lives. "We only get one life to live," she says. "I know every patient will benefit from chiropractic, and they don't have to rely on drugs and surgery." The joy she experiences when patients tell her chiropractic has changed her life makes it all worth it. In her spare time, Dr. Lacie loves playing volleyball""”you can catch her on the court in the winter and in the sand during summer. It's her number one passion outside of chiropractic, and she also plays in a lot of tournaments.
