I attended an appointment with my dad and Doctor Milena was very attentive and helpful. She went through all the procedures that he may have with a kind calm snd professional manner.
Quite a long wait to see Dr Leo but very satisfied with the meeting with her.
I was very impressed with Doctor Leo’s friendly professional manner. She put me at ease and explained everything clearly and concisely. I left the appointment feeling satisfied that I knew what ongoing treatment I would have and a timescale in which it would be completed.
It was the first time in a very long time that any medical professional at that level has made me feel completely heard and in no way rushed. Everything was explained simply and slowly and when necessary repeatedly. Thank you.
