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.
