Professor O’Donnell attended Medical School at the Queen’s University of Belfast in Northern Ireland between 1994 and 1999 where he graduated with distinction combined with the award of the Northern Ireland Medico-Legal Prize for Forensic Medicine. He completed his surgical training as a Specialist Registrar on the Northern Ireland Surgical Training Rotation between 2006 and 2015. He passed the FRCS Exit Examination at first attempt in 2012 and was recently awarded first place in the European Board of Vascular Surgery Examination in 2015. He has also completed the United States Medical Licensing Board Examinations.

During his surgical training Professor O’Donnell established a prolific publishing interest with over 100 publications in PubMed Indexed Peer-Reviewed journals, over 100 published abstracts and more than 250 international and national presentations. He has previously been awarded the Society of Vascular Surgery International Scholar Award, Society of Academic Surgery Prize and Belfast City Hospital Young Investigator of the Year. Written submission of theses culminated in the award of a Medical Doctorate in 2008 evaluating ischaemia-reperfusion in patients with peripheral arterial disease and a Master of Medical Science in Education for the Healthcare Professions in 2009 evaluating career choice in Foundation Doctors. He continues to lecture at the University of Ulster and is a regular reviewer for over 20 medical journals.

Completion of a Vascular Surgery Fellowship at the World-Renowned Mayo Clinic in the United States between 2012 and 2014 not only complemented his vascular surgery skills but facilitated endovascular proficiency for a range of minimally invasive treatments for complex arterial and venous disease. He was appointed as an Assistant Professor of Surgery at the Mayo Clinic and developed an interest in medical simulation and military trauma education. He has also passed the Physicians Vascular Interpretation Examination of the American Registry for Diagnostic Medical Sonography.

Recent appointment as a visiting professor to the Ulster University has confirmed his established interest in academic research and innovation for optimisation of vascular patient clinical care and overall safety. He is the current lead investigator for the UK Omniflow Bioprosthetic Graft Registry and is a faculty tutor for the Royal College of Surgeons Basic Surgical Skills and START courses. Professor O’Donnell was previously appointed as a Consultant Vascular and Endovascular Surgery at the East Lancashire Health Trust in 2015 providing patient care for the full remit of vascular diseases. He was vascular lead for internet web presence and media, clinical effectiveness and was a member of the Research and Development faculty at the East Lancashire Hospitals NHS Trust. He remains proud of the Diabetic Limbs at Serious Risk (LASER) service which was commenced in September 2015 and his supervisory role for Higher Degree Theses. 

His recent move back to the Northern Ireland Vascular Centre based at the Belfast Health and Social Care Trust in April 2017 recognises his continued commitment to high quality, patient focussed clinical care in one of the largest vascular units in Great Britain and Ireland. In Northern Ireland, he has NHS clinical privileges at the Royal Victoria, Belfast City and Altnagelvin Hospitals.

With regard to his Private Practice, Professor O’Donnell performs office consultations for all aspects of primary and complex arterial, venous and lymphatic disease at the Kingsbridge Private Hospital. In these centres, he provides the full remit of varicose vein treatment including endovenous radiofrequency ablation, foam sclerotherapy and microsclerotherapy as well as open surgery for complex or recurrent veins.
