Dear patients and friends,

I would like to inform you that I will be temporarily away starting May 1, 2026, as I undertake subspecialty training in Gastroenterology (Liver and Digestive Diseases) to further enhance my knowledge and clinical skills. During this period, a trusted colleague will be available to attend to patients in both the Koronadal City and Banga, South Cotabato clinics for new consultations and follow-up care.

Please note that there may be adjustments to clinic schedules in the coming weeks. For inquiries or clarifications, you may coordinate with the clinic secretaries. Rest assured that we will ensure a smooth transition and remain committed to providing you with the highest standard of care.

I also wish to express my sincere gratitude to all my patients for your continued trust and confidence. Thank you very much for your understanding!
