All the staff at Smile Tailor are wonderful! I moved my orthodontic treatment there and cannot recommend this place more! Dr Korosh Majidi did my braces and I am so happy with the results! I felt like he was genuinely invested in the results, and I actually really enjoyed my visits. If you are thinking about getting braces soon I highly recommend considering Smile Tailor!

Navid and Korosh have been amazing throughout my Spark aligners treatment at Smile Tailor...when other orthodontists had told me my teeth could not be straightened they have transformed my teeth and I've actually looked forward to my appointments! I had never thought my teeth could be as straight as they now. I can't recommend Smile Tailor is an investment but totally worth it!

Smile Tailor absolutely has my highest recommendation for an orthodontic practice. I've been here for about eight months for Spark Aligners and every appointment and encounter I've had has been positive so far. After having consultations at six (!) different private practices in London, I felt the most comfortable trusting my treatment with Korosh and Navid. It was the only practice that has two doctors looking at my teeth, ensuring quality control. They also entertained all of my calls and questions, providing me with all of the information I needed to make an educated decision. You can tell these aren't doctors who are looking to make a quick buck - they are professional, incredibly knowledgeable, and genuinely want the best outcome for your orthodontic health. Clear Aligner are an investment of time and money and I genuinely trust this practice. The place is impeccably clean and you receive great customer service - you know you're getting the value for your money. With about two months left in my treatment, I'm very grateful I chose this establishment and would recommend it to anyone seeking orthodontic care in London.

Fantastic service and lovely team. I had been in constant pain on my jaw muscles and jaw joint for 2 months. I saw Dr Korosh Majidi as I had heard stunning feedbacks about his treatments. After a thorough examination, he picked up the problem instantly and following the treatment, I woke up the next morning, completely free of pain. That was amazing! He definitely is an expert in his field, Thank you Korosh. Highly recommended.
