The doctor who saw me was very easy to talk to and put me at ease. She took time to explain my condition, options and treatment in a clear and friendly manner. I would definitely go here again and would definitely recommend it to others.

I was so grateful to find this clinic. As a tourist who was traveling through London from the states, and unfamiliar with where to go- Im so lucky that I found this clinic! The doctor that I met with, Dr. Vassiliou, was one of the kindest and most compassionate doctors that I have ever met with. She really helped to calm me down and created a comprehensive treatment plan for my flu and to help me rest so that I could endure the travel back home to the states. I will forever be grateful to her and her care!

Took my toddler for a chickenpox immunisation and the doctor was so nice and my daughter didn't even notice the immunisation or cry. She was happy to receive her sticker after too. Have been for other immunisations here too
