Over the 14 years that Dr.
Grentz treated patients as a family practice physician
and as an occupational medicine physician, he saw many
individuals who suffered from chronic neck and back
pain. Many patients continued to experience pain despite
the standard treatments. Although initially skeptical
of the Physician Neck & Back Clinics (PNBC) approach
of reconditioning the spinal structures and supporting
tissue through isolated strengthening exercises, Dr.
Grentz was astonished by the long-term results achieved
using this method. He has been treating patients as
a PNBC staff physician since 2000 and continues to
be pleased with the results many patients experience.
Dr. Grentz is also interested in sports medicine, health
promotion, and injury prevention.
