Meet Your Care Team

The multi-disciplinary team of clinicians are best in class in their individual professions. Each clinician follows the latest research, and treatment protocols are updated as new, scientifically documented tests and therapies become available.

Founders, Drs Vikki and Rick Petersen, DC, CCN, CFMP

Despite very different upbringings, Dr Vikki was born in New York City, while Dr Rick was born on a farm in Iowa, their meeting in Chiropractic University was the beginning of a great love.

Drs Petersen are both Certified in Functional Medicine and Clinical Nutrition and hold doctorates in Physical Medicine, through their degree in Chiropractic. Their broad base of training and expertise is what spawned Root Cause Medicine, a team of clinicians who collaborate to restore optimal health, without the use of drugs.

A love for each other and their children, a love for natural healthcare, a spiritual bond, and a life-long purpose to bring the best that drug-free healthcare has to offer to humanity, sums up their life together.

During over 30 years of marriage, they have spent little time apart from one another. Like all great relationships they are different in many ways, complementing each other with different strengths.

Getting to the Root Cause of why a body is malfunctioning is a passion they both share, and they are known for their innovation and unrelenting tenacity to help patients, which likely accounts for the high success rate that patients enjoy.

Drs Petersen are extremely proud of the teams they have created at the multiple Root Cause Medical Clinics and plan to continue expanding clinics around the country and internationally, while concurrently staying on the cutting edge of all that natural healthcare has to offer.
