Dr Leo, is a pleasure to see, friendly, empathetic and professional.
Very professiinal curteous and listned to my questions and concerns i wouldnt hestiate to recommend
I had a range of questions for the Doctor and she answered them clearly and patiently. Nothing was rushed
Dr Leo explained everything clearly to me and was very helpful. I felt very Anxious before I spoke with her, now I feel I am in good hands.
Went to see Dr Milena and she was kind, informative and really lovely and explained everything.
This was my first time seeing Dr. Leo and my experience was great. Dr. Leo made the appointment feel relaxed, I did not feel like she was trying to ‘rush me out of the door’. I also felt like she took her time to understand my experiences, she reassured me and confirmed next steps clearly.
Dr Leo was very professional and took time to explain everything clearly. She showed patience and understanding and put me at ease with her gentle and caring manner. I did not feel rushed, was given time to ask questions and Dr Leo ensured I had understood everything before I left the appointment. I have every confidence in her and am happy to have her involved in managing my condition.
Milena was incredibly helpful and knowledgeable. She explained everything brilliantly and her sheer professionalism and personality put me at ease from the very first minute of the consultation.
Dr Leo is a lovely person and a true professional. She spent a lot of time with me recently and explained everything in full detail that I could understand. Dr Leo has carried out a cardiac ablation on me 15 months ago which has been successful and has made my life so much better and along with the correct medication, my day to day life has been so much better. For this I am eternally grateful.
Given loads of easily understood information. I did not feel rushed, she gave me lots of her time
