Dr. V also serves as adjunct faculty at McMaster University in the Anesthesiology and Pain Management Department. Dr. Visnjevac enjoys teaching and inspiring medical students, residents, and pre-med students. He regularly gives lectures, teaches clinical workshops, and provides clinical bedside education, the last of which he feels is the most rewarding of the three.

Dr. Visnjevac is passionate about improving the quality of his patients’ lives and, as such, is an avid medical researcher. Although his two primary foci of research are (a) Radiofrequency Ablation (aka RFA or Rhizotomy) and (b) Ketamine Infusions, he is interested in a broad spectrum of research that can improve patient care in the field of Interventional Pain Management as a whole, including alternative uses of pain management medications like Low Dose Naltrexone (LDN) to cure and treat cancer. As such, Dr. Visnjevac leads the BPS Research Division.
