Transforming Lives Across the Globe with QN Care - Dr. Joyce Yeung in Hong Kong

We recently received a powerful testimonial from one of our QN Certified Practitioners currently practicing in Hong Kong. Her story is a shining example of how Quantum Neurology continues to transform lives across the globe — even in cases where traditional solutions fall short.

This practitioner, Dr. Joyce Yeung, who completed her chiropractic training in the U.S., had the privilege of being mentored by QN Master Practitioner Dr. Jen Hartley, DC during her preceptorship in Denver, CO. That mentorship — combined with the wisdom of Quantum Neurology — helped prepare her success in Hong Kong and assist in life-changing cases.

Meet Dr. Joyce Yeung, DC – QN Certified Practitioner:

Dr. Joyce Yeung, DC, earned her Quantum Neurology® Certification in May 2024 after completing her chiropractic education and preceptorship in the United States.

Dedicated to excellence, she returned to California to fulfill the hands-on requirements for QN Certification — a journey she describes as invaluable to her future in clinical practice.

Now serving patients in Hong Kong, China, Dr. Yeung brings a unique global perspective and a passion for neurological rehabilitation to her work. She is honored to be part of the QN community and continues to make a profound impact through her care across the globe.

“A patient came to me after undergoing pituitary surgery. As the surgical team removed the cotton balls from his nose the next day, he felt a twitch in his right eye. He quickly realized he could no longer move his right eye laterally. The doctors told him to rest and hope for recovery — but after a month with no progress, he was left with double vision, dizziness, and a dramatically altered quality of life. His future plans, including moving abroad, were put on hold. He felt hopeless...

After just one QN session, the swelling in his eye began to subside. And over the course of two months of care, his eye regained 90% of its range of motion, and his double vision continues to improve week by week. Now, he’s hopeful he’ll be able to drive again — something he thought might never be possible.

It’s fascinating how the motor nerve function recovered more quickly than the image-processing component involving the brain. This case has been such a joy to work with — a true example of how QN allows us to layer and stack healing protocols in a meaningful, individualized way.” - Dr. Joyce Yeung, DC, QNCP 

This is more than a success story — it's a reminder that hope is not lost when you understand how to activate the body’s healing intelligence.

We’re so proud of this doctor and grateful to Dr. Jen Hartley for passing on the wisdom and skill of QN with such care. These are the moments that show us what’s possible when we work with the nervous system rather than against it.

Side Note: both Dr. Joyce Yeung, DC, QNCP and her mentor Dr. Jen Hartley, DC, QNMPwill be attending the 2025 QN Homecoming Event! This is a rare opportunity to meet and mingle with some of the most talented and dedicated healers in the field — traveling from across the globe to celebrate, learn, and connect. We're honored that this event will offer an inspiring environment to engage with the global Quantum Neurology® community.
