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 Claire Tambellini

Dr. Claire Tambellini is the newest chiropractor at AHN. A recent graduate of Palmer College of Chiropractic, Dr. Claire is no stranger to AHN. She completed her internship at the clinic in early 2019. She enjoyed her internship experience with the staff and patients so much, she knew she wanted to be a permanent part of AHN.

Dr. Claire appreciates relieving pain by treating patients through natural processes. She has trained under Dr. Cathy in cranial adjustments and loves seeing pediatric patients.

Dr. Claire believes there is nothing greater than hearing patients say they are pain free. She also loves working at AHN because every patient is greeted with a smile and treated like family. This caring atmosphere is what makes AHN special.
