About Us

Welcome to Diamond State Chiropractic in Newark, DE

Spinal health is a critical aspect of your overall wellness. The spine plays a major role in helping you sleep, stand, and move properly. However, issues such as carpal tunnel syndrome, a slip, and fall accident, or a car accident can lead to spinal misalignment. At Diamond State Chiropractic in Newark, we have years of experience correcting spinal misalignments with natural and effective chiropractic care. Over time, chiropractic adjustments will relieve your pain, improve your range of motion, and enhance your body’s natural healing process.

After evaluating your musculoskeletal system, our chiropractor will tailor a chiropractic care plan to your personal needs. In administering the treatment, we employ various strategies, including exercise instruction, lifestyle guidance, nutritional counseling, and chiropractic adjustment. Through the combination of such approaches, we will address your discomfort at its source.

For more than 25 years, our chiropractors have helped people in Newark be more active, more productive, and lead healthier lives. You should not allow migraines, back pain, illness, injuries, and other ailments to hinder you from living the healthy lifestyle that you deserve.
