NOTICE TO MY PATIENTS and MEDICAL ASSISTANCE PROVIDERS
In light of the increasing reports of fake and falsified medical certificates being used to request medical assistance or medical leaves, I am implementing additional security and verification measures for all medical certificates issued under my name effective today, July 4, 2026.
These measures specifically the QR codes and validity portals are intended to protect my patients from misuse of their personal and medical information; prevent the unauthorized reproduction, alteration, or falsification of medical certificates; and to allow concerned institutions to verify the authenticity of certificates when necessary.
Please be advised that medical certificates issued prior to the implementation date of these additional security measures, bearing my signature in blue ink, remain valid and authentic.
Thank you for helping us uphold honesty, accountability, and trust in the use of medical documents.
