Patient Journey
Everyone’s experience is unique, but it may help to understand how we typically work together throughout your time with us. If you have any questions at any stage, we’re always here to help.
We often recommend that couples attend consultations together. This allows both partners to hear the discussion first-hand and ensures that any plans or next steps are fully understood and shared from the outset.
While every consultation includes a personalised follow-up report, there is no substitute for a thoughtful, in-person discussion. We take time to listen, explain, and support — whether it's a one-to-one appointment, or more often, a one-to-two conversation.
