Jefferiss Wing

I was delighted to find that I could now book an appointment for a sexual health check-up and wasn't disappointed. I was in and out in 25 minutes and my lovely nurse couldn't have been more friendly, helpful and thorough.

The staff at the Jefferiss wing were discreet, friendly and knowledgeable. I'd highly recommend.
