Welcome to Colorado Chiari Institute
Welcome to the Colorado Chiari Institute at The Medical Center of Aurora, is recognized as a Best Hospital by U.S. News & World Report, a leader in hospital safety by The Leapfrog Group, and a Magnet hospital for nursing excellence. The mission of the Colorado Chiari Institute is to provide high quality, compassionate care for those suffering from the Chiari I malformation and related disorders.
CCI is an outgrowth of The Chiari Clinic established by John Oró, MD, FAANS and Diane Mueller, ND, RN, FNP-BC at the University of Missouri Health Sciences Center in 1998 and the Chiari Care Center at The Medical Center of Aurora in 2005. Dr. Oró and his team have evaluated several thousand patients with CM I and he has surgically treated over 800.
Wellness is an integral part of care at CCI and we believe in treating the whole patient. By examining nutrition and wellness, we seek to identify issues that may be aggravating Chiari symptoms. Kimberly Sexton, MSN, RN, FNP-BC and supportive specialists assist patients in reaching overall health goals.
The Colorado Chiari Institute also specializes in the evaluation and management of persons referred following previous unsuccessful surgeries. While some may require revision surgery, others may have associated conditions that can be addressed. In addition, we evaluate persons with non-Chiari syringomyelia, and with tethered spinal cord.
Enhancing compassionate quality-care is our mission, and we do this through our commitments to research, education, and innovation. In addition to continuing our clinical studies and educational activities, we are currently developing an app to strengthen the link between our patients and the care team.
Just twenty minutes south of Denver International Airport, CCI is conveniently located near I-225.
