Serving Eugene/Springfield since 1991 Colfer Chiropractic Wellness Center has been serving the Eugene/Springfield community since 1991. Because you are a unique person, Dr. Nancy Colfer believes strongly in listening to you as an individual and tailoring your chiropractic care to fit your needs. It is her comprehensive approach to your healing and wellness that makes the work successful. Chiropractic adjustments, gentle manipulations of the spine, are powerful tools for healing and usually the cornerstone of Dr. Colfer's treatment approach. This is because chiropractic adjustments are so effective in correcting the cause of your pain: misaligned vertebrae, stiff spinal joints and tense muscles. After chiropractic adjustments, your joints move more smoothly and your muscles can relax, freeing the body's innate energy so you can function at your greatest potential
