Dr. Ogi Visnjevac is a pain management specialist at Cleveland Clinic Canada. Dr. Visnjevac has an extensive background in regenerative medicine techniques, ultrasound-based techniques, visceral pain management and cancer pain interventions along with management of common musculoskeletal and neuropathic pain states.

Born in Sarajevo and raised in Toronto, Dr. Visnjevac relocated to St. George’s University in Grenada to obtain his Doctor of Medicine. He went on to complete his residency in anesthesiology in New York before finishing his fellowship in pain management at Cleveland Clinic in Ohio. During his time at Cleveland Clinic, he was awarded the Caregiver Award for his compassionate clinical care.

Dr. Visnjevac treats all kinds of pain and is passionate about improving the quality of his patients’ lives. He is particularly interested in interventional headache procedures (nerve blocks in the head and neck to treat craniofacial pain and headaches) and epidurals for acute sciatica. Patients often see a profound reduction in sciatica symptoms if they receive treatment in the first few weeks or months.

A dedicated researcher, Dr. Visnjevac has been published in numerous medical books and journals and presented his findings at conferences across North America. He enjoys working in the community in a primary care setting and truly enjoys building a rapport with his patients. Dr. Visnjevac founded The Central America Relief Project, where he acted as president for ten years. He oversaw donations of medical supplies to Guatemala and El Salvador and managed Canadian volunteers.

Dr. Visnjevac enjoys teaching and inspiring medical students, residents, and other interested students. He regularly gives lectures and teaches clinical workshops and clinical bedside education, which he feels is the most rewarding of the three. Dr. Visnjevac currently holds the role of Adjunct Clinical Assistant Professor at McMaster University’s Department of Anesthesiology and Pain Management.

When he’s not seeing patients, Dr. Visnjevac loves spending time with his wife and kids. One of their favourite destinations is the Toronto Zoo.
