The Bonham Clinic is a doctor's clinic at 100 Peck Seah St, #11-16, in Tanjong Pagar, with a 4.4 Google rating.
A good general practitioner does more than hand over a prescription: they take a proper history, examine where it matters, and explain what they think is going on before ordering tests. A first visit goes more smoothly if you bring a list of current medications and any recent results, and it is always fair to ask what a treatment is for. Regulars tend to stay with one doctor rather than clinic-hop, since someone who knows your history makes better calls. City clinics are often busiest at lunchtime and after office hours, so an early slot usually means a shorter wait.
For anyone living or working around Tanjong Pagar, The Bonham Clinic puts a well-rated GP a short walk from the MRT and the office towers.
