John J. Riva DC MSc (epi):

Dr. Riva is an Assistant Clinical Professor in the Department of Family Medicine at McMaster University. He completed his MSc in clinical epidemiology at the Department of Health Research Methods, Evidence and Impact, at McMaster University. He has 20 years experience in chiropractic practice, with focus on musculoskeletal conditions in primary care.

He is an associate member of Cochrane Canada. He has contributed to various patient care clinical practice guideline groups in Canada and internationally: World Health Organization (WHO), World Allergy Organization (WAO), Kingdom of Saudi Arabia Ministry of Health, American Society of Hematology (ASH), American College of Physicians (ACP), Allergic Rhinitis and its Impact on Asthma (ARIA), Canadian National Pain Centre, and Canadian Chiropractic Guideline Initiative (CCGI).

Our Office:

For over two decades we have offered non-pharmacological one-on-one care to manage common conditions such as sports injuries, low back pain, neck pain and headaches. We accept WSIB (worker's compensation) and motor vehicle accident claims. We offer care for conditions related to the extremities (i.e. arms and legs) and do not limit our practice to spinal conditions. We also provide orthosis in the form of custom-fitted orthotics for shoes or braces when prescribed by your family physician or medical specialist.

We take an evidence-based approach to the care we provide. We do not promote lifelong care; but rather encourage you to stay as active as possible and come see us when you feel you need to receive care. All of our patients are provided with a few daily exercises to help them manage their condition in a self-directed fashion.

Our office works with your other various providers and supports ongoing communication with them to offer you, the patient, the best possible care. With your permission we will provide ongoing communication to your family doctor, specialist, or complementary medicine provider.

Please note that we are a formal teaching location for upcoming health care providers. As a result, we will occasionally have students from medicine or pharmacy doing observations at the clinic.

Services to Expect:

You can expect to have an intial interview and evaluation regarding your problem. We use techniques that are only taught in accredited educational institutions. We realize that manipulation of the spine, especially of the neck, can be a concern for patients. Our office offers many other physical therapy, muscle, exercise and movement techniques that do not involve spinal manipulation. As a patient, it is always your choice what procedures you have performed on you during a visit.

Chiropractic care and custom-fitted orthotics are often covered by third-party insurances through you or your spouse's benefit plans. For approved WSIB (worker's compensation) and motor vehicle accident claims, services are fully covered.
