I've had a good experience at Portman Smile Clinic. All the staff have been really friendly and helpful. Appointments have always been on time and everything has been explained clearly to me. I'm really pleased with the results, my teeth are now lovely and straight.
The lady on reception was super friendly and professional with my son who has special needs. He was due to have his braces taken off. The dental technicians were equally friendly, professional and patient with him. He was very nervous but they were very reassuring. Thank you.
