• JNA's Philosophy - A Holistic Approach

    Chiropractic is a complementary and alternative medicine health care profession and an approach to healing concerned with the diagnosis, treatment and prevention of disorders of the neuromuscular system and the effects of these disorders on general health.


    Chiropractors emphasize manual therapy including joint adjustments and manipulation with particular focus on joint dysfunction. Although a wide diversity of ideas currently exists among chiropractors, we share the belief that the spine and health are related in a fundamental way, and that this relationship is mediated through the nervous system. Chirporactors examine the biomechanics, structure and function of the spine, along with its effects on the musculoskeletal and nervous systems and what they believe to be its role in health and disease.


    Growing up on an organic farm, Dr. Domm was exposed to chiropractic medicine. The family doctor was a chiropractor ( Dr Paul Neidert) believing in natural medicines for healthcare. As a child, she went to the chiropractor for treatment and was given natural herbs to take to rebuild her immune system when she was sick. When injured, she went to the chiropractor for treatment and rehabilitation.


    Dr. Domm's early experiences with natural medicine allowed her to choose a natural way of life instead of filling her body with prescription drugs and quick fix medicines.

    As a sports chiropractor, she been exposed to all types of athletes and has an impressive resume of clients, including:

  • Some of Dr. Domm's Clients include:

    NY Giants NFL Football

    US Women's Soccer

    US Women's Pro Volleyball
