Innovative Pain Specialists in Arlington Heights and Libertyville, Illinois, was founded in 2011 by pain management specialists Paul Marsiglia, DO, and Demetrios Louis, MD. At the time, there was a strong need for more research-proven, innovative treatments for those suffering from pain. We felt strongly that we could bring that type of care to the community where we grew up and currently reside. We believe that we have accomplished this goal, and we continue to stay on the forefront of technology as we continue to keep up with the latest treatments for those suffering from pain. We primarily focus on minimally-invasive orthopedic and spine treatments to alleviate pain, and we utilize the most advanced image-guidance and technology available today to ensure safety and optimize effectiveness.


Dr. Paul Marsiglia and Dr. Demetrios Louis first immersed themselves in the field of Interventional Pain Management while at Rush University Medical Center as co-residents. Upon completion of their residency programs, they fine-tuned their skills and expanded their knowledge base at the most prestigious multi-disciplinary program in the world at Harvard Medical School in Boston, Massachusetts. In fact, the program at Harvard University is the only program in the world to have been recognized three times as a Center of Excellence by the American Pain Society.  Dr. Paul Marsiglia and Dr. Demetrios Louis are both proud and grateful to be able to bring their vast knowledge and clinical abilities to the communities where they grew up so as to help patients conquer their pain and regain their quality of life.


As of 2022, Dr. Marsiglia and Dr. Louis have cared for over 12,000 patients.  Although their practice is largely outpatient in nature, they continue to maintain staff privileges at Northwest Community Hospital (Arlington Heights, IL) and Advocate Condell Medical Center (Libertyville, IL).  In addition, they regularly perform procedures and minimally-invasive surgeries at Hawthorn Surgery Center (Vernon Hills, IL) for those suffering from various orthopedic, neurological, and spinal conditions.  Our doctors are leaders in the community, well-respected by their peers, and have even collaborated with Northwest Community Hospital to establish the NCH Back and Spine Clinic.  As founding members, we work closely with therapists, sports physicians, and neurosurgeons to ensure timely, coordinated, and appropriate care for our patients.
