About
The story
Ayhan Yener grew up in Eskişehir, finished Eskişehir Anatolian High School and studied medicine at Eskişehir Medical School. In 1991, as a medical student, he co-founded the rock band Haramiler with classmates. Medicine and music ran in parallel for years.
After graduating he worked as a physician for about a decade. In the mid-2000s he was practising at Dünya Göz Hospital in Ataköy, Istanbul.
He then moved into medical affairs, first as a medical manager at two pharmaceutical companies in Istanbul, then at GEN in Ankara. Over twelve years there he ran a business unit for four years and served as Medical Director for five. He led eight medical managers, twenty-five science-service specialists and the company's ethics and compliance function, working on therapies for rare diseases in Türkiye and neighbouring regions.
“I would rather talk you out of a treatment than give you one you do not need. Good work of this kind is mostly restraint, anatomy and honest follow-up.”
That work meant reading clinical trials closely, questioning claims and keeping patient safety above sales targets. It is the same discipline he applies with patients today: an accurate diagnosis, approved products, conservative doses and a result that looks like you on a good day.
