Here’s what our patients have to say…

Each member of the team that we dealt with, whether medical or support staff, were excellent.

The support has been excellent throughout.

We had a clear plan from early in the process and managed to follow through with only a couple of amendments (which we made).

We have been impressed and very grateful for the speed at which our queries have been responded to.

Parents of Isaac, age 9, Isle of Wight

Excellent. All of the team were very efficient and we found the chart with the dates and dosage for the updosing appointments particularly helpful.

The team were easy to reach, including direct contact with the consultants, even at the weekend and over holiday periods.

The overall experience was excellent.
