- Excellent and reassuring service
- Mr Nnadi was very kind and helpful. Would recommend.Doctor's response -Thank you for your kind words. Much appreciated
- Perhaps a pop-up coffee shop would complete the picture here, lacks nothing else
- I am over the moon with the outcome of my daughters surgery. Her recovery was so quick and she is doing incredibly well with no more pain. Her scar is lovely and straight. Mr Nnadi was brilliant throughout the whole process.Doctor's response -Thank you for your comments. I hope your daughter has continued with her recovery and is doing well
- I had 3 consultations, each lasting for ~5 minutes. They could have been done over the phone since there were no physical examinations or an explanation of the scans. Waste of time and money. Why would someone even charge for consultations like these? Terrible experience.
- Friendly and honest
- Everything was fine and very professional. I didn't have to wait, and I was thoroughly examined.
- Mr Nnadi has provided excellent care for my son. He takes the time to explain everything fully and clearly. I'm very glad to have Mr Nnadi as consultant for my son.
- Dr Nnadi was extremely professional on each occasion that we meet him. He spoke directly to my daughter and fully involved her in her treatment plan. He also took the time to answer an extensive list of questions we had about her treatment.
- Thanks so much Dr
