Graduating with Honours from the BScN Collaborative Nursing program at Ryerson University in 2015, Yuriy initially pursued Mental Health & Addictions as a field of interest where people's needs were largely underserved. In working at Unity Health Toronto (previously St. Michael's Hospital) downtown Toronto, Yuriy realized the gravity of how fragmented  the healthcare system really is and how little could be done at the bedside to change systemic outcomes after-the-fact. Yuriy made the decision to pivot from providing acute care to target health prevention and health promotion instead and enrolled in the MN-PHC-NP program, graduating with Honours at Western University in 2019.

Since graduation, Yuriy has focused on education, primary care, and clinical research and entered the academic world reinforcing positive patient care outcomes with his students in the IEN, PSW, RPN, and BScN programs at George Brown College. Yuriy has extensive experience in travel medicine from working at the Travel Vaccine Clinic and has solid experience in clinical research, previously with Cliantha Research, and currently at Apex Trials as a Nurse Practitioner/ Sub- Investigator.

Yuriy continues to provide acute care services on a casual basis at Unity Health Toronto as the need for compassionate care is more dire than ever before and continues to walk the path to love all, trust a few, and do wrong to none (ref. W. Shakespeare).
