Created by someone who understands
I'm Dr Krishnan Pasupathi — a GP with 29 years in medicine. But I'm also a patient.
I live with multiple long-term conditions and I'm in the clinically vulnerable category. I know what it's like to sit in a waiting room, anxious about results. To hear words you don't quite understand. To leave an appointment and realise you forgot to ask the one question that was really on your mind.
That's why I built these tools — to help you feel more confident and prepared.
