About Greenway Health Center.
To change health care in the Triangle. The future is looking bright.
Greenway Health Center was founded in 2011 by Dr. Greg Barnes, Doctor of Chiropractic and Certified Functional Medicine Practitioner (CFMP), and his wife Jani, right here in Raleigh, North Carolina. Since opening, Greenway has grown into one of the largest natural health care clinics in the Triangle, helping tens of thousands of patients across Raleigh, Wake Forest, and the surrounding communities experience true, lasting health.
Our approach has always been the same: identify and correct the root cause of your health problems — not just mask symptoms. Through advanced corrective chiropractic care, functional medicine, spinal decompression, and SoftWave Tissue Regeneration Therapy, we offer Raleigh families a comprehensive, drug-free path to healing that goes far beyond a standard chiropractic adjustment.
We believe your body's natural, default state is health. When chronic pain, fatigue, hormonal imbalances, digestive issues, or injury show up — that's a signal something is interfering with your body's ability to heal. Our job is to find that interference, remove it, and restore your body to its full potential.
For us, this is bigger than popping joints or straightening spines. We are a holistic health center dedicated to helping individuals and families in Raleigh live their healthiest, most vibrant lives — free from dependence on medications and free from constantly thinking about sickness. After all, your health is your most valuable asset.

Dr. Barnes
OWNER AND DIRECTOR
Dr. Greg Barnes is the owner and director of Greenway Health Center and Triangle Health Center, where his mission is simple: help people get healthy and stay that way — using a root-cause, functional medicine approach that looks beyond symptoms to what's actually driving them.
Over the past fifteen years he has pursued everything he could learn about optimal health, longevity, anti-aging, and human function — a pursuit that has earned him multiple degrees in natural health, including Doctor of Chiropractic, Doctor of Natural Medicine, certification in Functional Medicine, and numerous additional credentials.
He especially loves working with families and motivated individuals from every walk of life — people who don't just want to feel better, but who want to build the kind of health that lasts.
Outside the office, Dr. Greg's world revolves around his wife Jani; their three children, Nora, Leo, and Gabie; and their three dogs, Coco, Juno, and Winnie. He's a die-hard Carolina Hurricanes fan — and has the privilege of caring for some of the players themselves. When he's not at the rink or with family, you'll find him reading, studying business and finance, or investing in like-minded companies and projects.

LIZ
CHIROPRACTIC ASSISTANT
Arcelia "Liz" Lizeth Vargas was born in Michoacán, Mexico, and raised in Raleigh, North Carolina, with a few years spent in Warsaw, NC — an experience that gave her a deep appreciation for connecting with people from all kinds of communities. As a bilingual Chiropractic Assistant, she's passionate about making every patient feel comfortable, supported, and truly cared for.
Before stepping into the chiropractic world, Liz worked as a case manager at a car accident law firm, where she sharpened her communication skills, attention to detail, and people-first mindset. She brings all of that into the clinic today — building trust with patients and making sure their experience is a positive one from the very first visit
Warm and easy to talk to, Liz takes pride in connecting with patients on a personal level and bridging the language gap for both English- and Spanish-speaking families.
Outside of work, she's a proud mom to her 6-year-old son and 3-year-old daughter, who keep life busy, joyful, and full of love. In her free time she enjoys diamond art, and she's currently focused on her own health journey — bringing that same positivity and determination into her work every day.

Together they have two children and a Yorkie-Bichon.

She is also a prominent member of a Raleigh motorcycle club dedicated to giving back to the community through scholarships for underprivileged children and other volunteer efforts.
What is Chiropractic?
Founded in 1895, chiropractic care has grown into the largest natural health care field in the world — and for good reason. From its very beginning, chiropractic has been built on one core principle: find and correct the underlying cause of pain and dysfunction, not just treat the symptom.
At the center of chiropractic care is your spine and nervous system. Your nervous system is the master control system of your entire body — governing sensory function, muscle movement, organ health, immune response, mood, hormone regulation, and every other process that keeps you alive and thriving. Simply put, you experience your entire life through your nervous system. If you want to eliminate chronic pain, boost your immune system, improve your energy, and age well, a healthy spine and nervous system are the foundation.
Just as your body has normal ranges for blood pressure, heart rate, and body temperature, your spine has a normal, healthy alignment. When that alignment is maintained, your body communicates efficiently and functions at its peak. When it's disrupted — even subtly — the interference that follows can affect far more than just your back.
Modern life puts unprecedented stress on our spines. Desk jobs, prolonged screen time, poor posture, and hours of sitting create repetitive micro-traumas that accumulate silently over time. Left undetected or uncorrected, these micro-traumas progress into chronic pain, disc problems, nerve compression, degenerative joint disease, and systemic health issues that most people never connect back to their spine.
At Greenway Health Center, our Raleigh chiropractors use advanced corrective chiropractic techniques — including BioStructural analysis, computerized posture analysis, range of motion tracking, digital X-ray, and nervous system assessments — to identify exactly where interference exists in your spine and nervous system, and build a personalized care plan to correct it at the root. For patients who need it, we also offer cutting-edge therapies like SoftWave Tissue Regeneration Technology and spinal decompression to accelerate healing and deliver lasting results.
