    Dear Cocoona & Dr. Sanjay, Thank you so much for my Breast Augmentation procedure. Its 1 month on and I could not be happier with the result . All the way through from the initial consultation to the post op checkups, all your staff has been wonderful. The Dubai London Clinic for the surgery was fantastic. I would definitely recommend to others to Cocoona. Now if you could fix my handwriting skills please?
    Thanks again.

    Dear Lovely Staff of Cocoona, I love the environment of the Clinic, staff is so beautiful & positive always smiling. And Dr. Sanjay is the best, friendly, positive & smart. I am very happy with the procedure that I have done & I strongly recommend anyone who is reading these to please “go for it”. Mini and the other Nurses around are dolls, cute and positive. Love the All!
    Thank you & Best Regards

    I want to thank you for the great effort and expertise that you put in the hair transplant procedure which you did on me. You have fixed a big cut from a previous, very bad hair transplant in Jordan. It kept me very nervous and uncomfortable for very long time. Now, after conducting this surgery by you, I feel very very happy because the cut is almost gone. I like your personality and professionalism. I am really glad that I made a decision to come to Dubai and conduct the surgery at Cocoona Clinic Thank you very much.
