Aimee Karnath

Born and raised in the mountains of Colorado, Aimee has always felt a closeness to nature and wildlife. Her passion for integrative and alternative medicine came from a long journey to wellness. At the young age of 9, Aimee was hit with a plethora of life-threatening conditions. Her life as an outdoor enthusiast changed drastically when the reality of hospital stays, surgeries, and clinical trials hit. It wasn't for nearly 20 years that conventional doctors were able to determine the cause. Thankfully, Aimee had turned to alternative forms of treatment 8 years prior to her official diagnosis. Within a year of starting natural treatments, improving her diet and lifestyle, Aimee was able to stop more than a dozen prescription medications, along with two infusions, with her blood markers not only holding steady - but actually improving. Aimee was determined to help others in similar situations find hope and healing. As such, she completed her bachelors with a degree in Integrative Health Care. Through the trials and tribulations, good certainly did prevail in the end. As Aimee always says, "Challenges are what make life interesting; Overcoming them is what makes life meaningful." Aimee is now healthier than ever - living for outdoor adventures, always rooting for the Buffalo Bills, and enjoying life with her husband and two wild pups.

About Us

The Practice

The name ‘Cardea’ (CAR-DAY-UH) is attributed to a goddess of classical Roman mythology whose name is derived from the Latin root word ‘cardo’ (i.e.: cardiac, cardinal) meaning hinge or axis.  She was therefore considered to be the goddess of health, of thresholds (both physical and spiritual), as well as a goddess of the center.  Her power is to open that which is closed, and close to that which is open – and to promote a centeredness which will lead to improved health and well-being.  It is her aspects of acceptance, grace, patience, and compassion which form the core of our principles and approach to healthcare at Cardea Health Integrative (CHI).

Cardea Health Integrative

was formerly known as Preventive Medicine and Wellness Clinic.  It was founded by Dr. Robert Barnes, DO and was located in Fredonia, NY in 1994. After 26 years practicing general surgery and family medicine, he turned his attention full-time to promoting and practicing alternative medicine.  Dr. Barnes has truly pioneered the integrative/preventive model of medicine in our area and we pay homage to him as we move forward and continue to aid in shifting the healthcare paradigm here in the WNY region.  Many of his long time patients remain with the practice to this day.  Dr. Barnes transferred ownership of the practice in 2015 to Dr. Jennifer L. Jennings, and it was subsequently rebranded as Cardea Health Integrative, or CHI.  Dr. Jen had been working with the practice for years and was the logical choice to take the solid foundation given by Dr. Barnes and bring it through to its next evolution.

Our one of a kind property is located on the “Twin Elms” Estate in Aurora, NY.

It has quite the history.
