Consultations can be arranged either via Sonja's practice manager or, more quickly, by calling the hospital outpatients department directly via the numbers below:

King Edward VII's Hospital – 020 7467 4550
Parkside Hospital – 020 8971 8026
Spire St Anthony's Hospital – 020 8335 4679
Ashtead Hospital – 01372 221 400
St George's NHS Trust – 020 8725 4773

The date and time of surgery can be arranged with you at the time of consultation. This allows us to accomodate time convenient for you against my operating schedule and availability straight away. Confirmations can be made later with my practice manager too. Once the date is agreed, the practice manager will process the booking and arrange preoperative assessment and admission to the hospital.
