Dr Hisham, a Longevity Medicine Doctor in Singapore, is a leader in integrative and preventive medicine, dedicated to optimising people’s healthspan to achieve lifelong wellness. Sparked by his training in accident and emergency, he realised that to achieve true and lasting health requires a proactive approach – not a preventative one.

With over 25 years of medical expertise, Dr Hisham creates custom healthcare plans that enhance overall well-being and vitality and enrich the quality and purpose of people’s lives rather than simply extending them.

As the Founder of Bartley Clinic in Singapore, he integrates personalised medicine, preventive care, and modern digital health solutions. He has been a consultant for leading health institutions, including Penn State University (U.S.), Duke-NUS Medical School, Chi Longevity (Singapore), Deloitte Consulting and the Singapore Ministry of Health.

A sought-after physician and educator, Dr Hisham advocates for transforming healthspans and lifespans through evidence-based innovation. He continues to shape the conversation around integrative medicine, science, compassion, and empowerment for a new paradigm in well-being globally.
