Helping your family's health — with a doctor who listens.
Personalised, unhurried care from a GP serving Craighall Park, Johannesburg, Randburg and Sandton — consultations built around you, not a clock.
Care that puts patients first
I understand that many patients feel unheard, rushed, or overwhelmed when it comes to their health. My goal is to provide a different kind of medical care — one where patients feel comfortable, listened to, and genuinely supported.
I enjoy working closely with patients to help them better understand their health and create manageable treatment plans that fit into real life. Whether you're dealing with ongoing symptoms, chronic health concerns, preventative care, or simply wanting to feel your best, I aim to provide thoughtful and thorough care every step of the way.

More time with your doctor, without insurer limitations
My practice operates independently of medical aid and insurance networks — which means consultations stay focused on personalised, high-quality care, without the time limits or restrictions often imposed by third-party providers.
Payment is required at the time of consultation. An invoice can be provided for patients wishing to submit claims directly to their medical aid or insurer for possible reimbursement, depending on individual plan benefits.
