Worth knowing
- A retail listing describes his book as an Irish Times number 1 bestseller. This is a publisher or retailer marketing claim that was not independently verified in this research. amazon.com
- His entry on the Irish Medical Council register, including registration number and specialist-division status, was not checked during this research. Patients can look this up directly. medicalcouncil.ie
- No US board certification (ABMS) was verified for him, and no US National Provider Identifier was found, so no Open Payments industry-payment record could be looked up. doximity.com
- A Doximity listing places him in La Jolla, California. This most likely reflects his earlier training period at Scripps rather than a current practice location, but that link was not confirmed by him. doximity.com
