Alison Greenberg

Alison Greenberg, MS, APRN, FNP-BC is a board certified family nurse practitioner. Having had two chronic childhood illnesses and a pediatrician father, the healthcare system has been familiar to her for as long as she can remember. In 2007, a serious bike accident fueled her motivation to heal herself and sparked a keen interest in health and wellness as well as a desire to provide humane, therapeutic healthcare.

She has always been passionate about healing modalities and nutrition, so deepening her knowledge in these areas for the past 16 years was a natural path for her. She is currently working towards functional medicine certification through The Institute for Functional Medicine (IFM). She is excited to join Cardea and looks forward to partnering with and supporting her clients on their path to optimal wellness.

After receiving her Master’s degree from Georgetown University in 2017, Alison worked as a primary care provider on Buffalo’s lower west side, which reinforced her commitment for empowering individuals through education, preventive medicine, and psychosocial support. Her clinical background includes critical care oncology and lead research assistant on a medical expedition in the Nepal Himalayas utilizing yogic breathing techniques to modify risk of high altitude sickness. She received her BSN from New York University in 2010.

Her approach to healthcare is largely informed by her background as an fine artist. She holds a BA in Art Practice from the University of California at Berkeley, and has been a lifelong painter and cellist. She is also an avid gardener and nature lover.

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.
