About Us

Glenn P. Sorrentino, DC

Certified in Functional Medicine

An expert in the biomechanics of the body, Dr. Sorrentino has pioneered many successful protocols used at NJ Spine & Joint, including integrated treatments employing cold laser therapy, physiotherapy, and chiropractic techniques. Certified in Sports Medicine, Dr. Sorrentino has helped thousands of patients suffering from neuromusculoskeletal conditions, including shoulder, knee, hip, back, neck, elbow, ankle, and foot injuries. His wealth of experience includes more than 20 years in New York City, where he treated patients from all walks of life, including professional athletes and celebrities. Dr. Sorrentino enjoys helping the people of Cedar Grove and the surrounding communities, as well as many patients who travel quite a distance for his expertise. 

Dr. Sorrentino’s extensive knowledge, friendly demeanor, and unique treatment approach have made him a patient favorite. His passion and commitment are evident in the success stories of his patients, many of whom thought their cases were hopeless.

A body biomechanics expert, Dr. Sorrentino, explains that pain in one area is often “the result of imbalance or weakness” in another area. “For example, knee pain is often caused by the hips being out of alignment, and shoulder pain almost always has a neck component.”

Specialized Treatment Protocols

Dr. Sorrentino uses an integrated treatment approach to get the best results. The protocols, which are customized for each individual, utilize the safest and most advanced non-surgical technologies and treatments available. 

“We have many patients who have been in pain for years and have tried other therapies, and they are amazed that their pain actually goes away with our treatments,” says Dr. Sorrentino. “It’s important for patients to understand what’s causing their pain and how our customized treatment protocols can help them.”

Dr. Sorrentino treats patients of all ages, including many high school and college athletes who are benefiting from cold laser, which is the same technology widely used by professional sports teams.
