Mark Chang M.D.

About Dr. Chang

Dr. Chang has been one of the leading spinal surgeons in the area stretching from Joliet, IL to Valparaiso, IN for over 30 years.  During this time, he has treated more than 100,000 patients and performed over 7000 surgeries.  Most likely one of your friends, family members, or neighbors has seen Dr. Chang.  He combines exceptional surgical skills with gentle, compassionate care.  He has committed himself to advanced minimally invasive techniques and introduced arthroscopic microdiscectomy to our
region in 1997.  

The field of orthopedics encompasses the non-operative and operative treatments of musculoskeletal disorders, including those of the spine.  Because
of the complexities, however, most general orthopedists do not perform spinal surgeries.  Instead, usually only those who pursue additional training, called a fellowship, in spinal disorders carry out these operations. 

Fortunately, Dr. Chang received a solid foundation in spine care at New York University Medical Center, and then completed his training at State University ofNew York-Syracuse Medical Center, one of the nation’s top spine fellowship programs.


 Under the direction of Dr. Hansen Yuan, an internationally renowned spine surgeon and past president of the North American Spine Society, Dr. Chang had gained valuable insight in understanding spinal anatomy, function, and form as they relate to the whole person.  Even though mastering precise surgical skills, Dr. Chang had learned to value non-operative care.   Correspondingly, less than ten percent of Dr. Chang’s patients have undergone surgery since he has been in private practice.  

Yet while emphasizing a non-operative approach, Dr. Chang continues to perform among the most spinal surgeries in the Chicago area.  This extensive volume of cases has translated not only into technical proficiency but also innovative ideas to make surgeries safer and more effective.  His vast experience has not gone unnoticed.  Dr. Chang is a much sought-after speaker for regional and national conferences.  In addition, numerous spinal companies have requested his input and advice on new implant and instrumentation designs.  Throughout his career,
Dr. Chang has earned a strong reputation for the highest professional and ethical standards.
