Dr Aywin established a rapport quickly, was able to explain potential diagnoses clearly and set out an effective path to resolving my concerns. His communication of results was excellent, delivering the headline first and then giving more detail afterwards. His patient letters were clear and prompt. Nobody wants to be in a position where they need to see a specialist, but I must say that I enjoyed talking to Dr Aylwin, and would choose him again if similar issues arose.

Dr Aylwin has been very helpful in discussing my thyroxine dosage during pregnancy. It’s been easy to get appointments, he doesn’t rush the appointments and I feel I always have enough time to ask questions. He writes to me quickly after the appointment and the information in the letters is always accurate and as discussed (which is often not the case with other consultants). Thank you.

I’ve met Dr Simon Aylwin few times this year for a viral thyroiditis, that he successfully cured. In every occasion he was always very polite, professional and clear. He is a very competent and humane doctor, he welcomes you with a smile and makes you feel comfortable. He listened to me very carefully and was open for any questions, you can clearly see that he cares about his patients. After each visit he would send me and my GP a very clear and detailed report. My entire experience with doctor Simon was extremely positive. Nowadays it is very rare to find an exceptional and humane doctor like him.
