Bilal Khalid co-founded PHC with his brother Dr Omer Khalid after recognising a fundamental gap in modern healthcare — the absence of personalised, preventative, and truly patient-centred care.

His path here was shaped by three things: a lifelong passion for fitness - he is a qualified personal trainer - growing up alongside two brothers in medicine, giving him an early, honest view of both what healthcare can achieve and where it falls short, and an instinct for business inherited from both sides of the family with deep entrepreneurial roots. Together, they made founding PHC feel less like a decision and more like an inevitability.

Together, Bilal and Omer have carefully curated a team of leading practitioners and consultants across clinical, strategic, and operational disciplines - each chosen not only for their expertise but for their shared belief in a better model of care.

His background in law, finance, and business management gives him a strong foundation in strategy, operations, and compliance - skills he applies to building PHC into a model that is as well-constructed as it is well-intentioned. His long-term ambition is to help shift healthcare from reactive treatment to proactive, personalised wellbeing.
