Dr Behar was very calm and personable. He listened and asked questions about my health, history and symptoms. He did an ECG during the consultation and then advised on 3 further tests. He put everything in a letter to myself and my GP within 24 hours.

There was a slight delay at the start. It would have been useful to have a text chat function at that point to understand the reason for the delay.

Your trust is our top concern, so providers can't pay to alter or remove reviews.
