Meet Our Doctors

Dr Cathy Subber

Dr. Cathy Subber has been a fan of chiropractic care since her springboard diving accident in 1990. Chiropractic care helped her overcome her injury and started her down the path of helping others. A native of Clinton, New Jersey, Dr. Cathy attended the Palmer College of Chiropractic in Davenport, Iowa. In 1999, not long after graduation, she moved to Naperville, Illinois. There she opened Advanced Health of Naperville — providing care for all ages, including chiropractic adjustments, cranial adjustments, physical therapy and massage therapy.

Dr. Cathy provides both pediatric and adult chiropractic care and is one of the only doctors in the area trained for upper palate and cranial adjustments. These adjustments are beneficial from issues ranging from nursing/feeding challenges, colic, torticollis, ear/sinus issues and reflux in babies to TMJ, dizziness, headaches, sinus congestion and ear issues in adults.

Dr. Cathy is also the founder of The Branch, a community where moms connect to empower and engage with each other. Learn more at

Dr Pat, Naperville Chiropractor

Dr. Patrick McAndrews grew up listening to the stories of his father and grandfather, both chiropractors, about how they changed the lives of their patients. Dr. Pat always knew he wanted to be a chiropractor and never considered another career.

A graduate of Palmer College of Chiropractic, Dr. Pat loves being able to live out the same kind of stories he heard growing up – the ability to help patients find relief and be their best physical selves. He still finds it amazing that something that seems so simple to him can provide such dramatic impact to patients. And his patients are the best part of his job.

Dr. Pat and his wife have eight children, three boys and five girls. With the boys out on their own and all the girls in college, Dr. Pat finds himself with a little more free time, so he and his wife, Vicki, are learning West Coast Swing dancing.

Dr Christine of Advanced Health of Naperville

After a traumatic jet ski accident at the age of 15, Dr. Christine Wilkerson had tried just about everything to ease the pain. Then she tried chiropractic. Just one adjustment gave her more relief than she had ever known – and inspired her to become a chiropractor.

Dr. Christine has been in practice since 2012 and specializes in pregnancy, pediatrics and adult care, employing the most appropriate and effective treatment from her wide-ranging skill set. Webster Technique certified, Dr. Christine helps expectant mothers have a more comfortable, safer, and easier birthing experience. She cares deeply about educating patients on how to regain their health naturally, teaching them about rehabilitative exercises and nutrition and lifestyle modifications that can empower them to take control of their health.

AHN is special, she says, because the practice brings so many different tools together to personalize each patient’s treatment. Few offices offer such a diverse range of therapies and treatments under one roof.

A graduate of Palmer College of Chiropractic, Dr. Christine is married with three young daughters and enjoys traveling and making memories with her family.

What drives a high-energy guy, fitness fanatic and exercise guru to become a chiropractor? As someone who spent years as a personal trainer, George Tune has seen first-hand just how chiropractic can affect all the systems in the body to boost its own innate healing. In fact, this is what led George to go to chiropractic school.

A previous group fitness instructor at AHN, George says AHN’s friendly, welcoming and patient-centered approach has earned it the reputation as “The Happy Place to Heal.” And according to George, there’s no better feeling than when you adjust someone and see the joy on their face because the pain is gone.
