I've had 3 rounds with Create. My first was in Wimbledon (before the St Paul's clinic was opened) and then the 2nd and 3rd with them in St Pauls.
I've also had rounds at Lister and Chelsea & Westminster, and so far, Create Wimbledon has been my 'favourite'. Or maybe 'least worst', because they are never nice!
The building is a bit odd and feels more like a job centre or dentist than somewhere doing advanced medical procedures, but they got the job done. The appointments ran more or less on time, and it is easy to get to by train or car.
The big advantage for me of Create over the other clinics is that you are only seen by doctors, who make the treatment decisions there and then. With the other 2 clinics I've been to, you see a sonographer, who does the measurements, then sends you back to the waiting room again, then you see a nurse, then you get a call sometime later in the day from a doctor. With C&W, I went 2 rounds without seeing a doctor once, apart from in the theatre before egg collection and transfer.
With Create, you get scanned by the doctor who tells you there and then what meds you need, or when you next need to be scanned and what blood tests you need. If the blood tests reveal any changes need to be made to your meds, they'll phone you and let you know.
And they got me pregnant twice, which is the main thing!
