Bridget Shirlow


Dr Doreen and her team have been fabulous. Throughout my treatment she has been accommodating and always quick to respond to any questions and queries. I’ve been extremely happy with the results of my treatment and cannot recommend this practice enough!

Maureen Lolo


Friendly, prompt and professional service from all of the staff. Doreen was referred to us by our pediatric dentist who said she is one of the best and I have to agree. She listens to what you want to improve and finds the best options for you to choose from and she is fabulous with children too.

Hafsa Ashfaq


My daughter got her braces one and a half year ago from Dr Doreen. She needed an expander as well and the results are amazing. Always organised, on time and communicates clearly. Recommended her to other friends and they got awesome results as well



Amazing service, did an excellent job on my teeth. Dr Doreen is highly qualified and competent and extremely accommodating and easy to work with. The whole staff is fantastic. Would 100% recommend too anyone seeking orthodontic treatment of any sort.
