He performed breast surgery on me last month, addressing multiple issues including reshaping and reconstruction. I am immensely grateful to him as he has changed my life. I was under a lot of stress due to my illness. He is one of the best plastic and cosmetic surgeons in the twin cities of Rawalpindi and Islamabad. May Allah grant him a long life and further success. After the surgery, Alhamdulillah, I am 100 percent satisfied. I thank Allah immensely for blessing me with such a great doctor. Thankyou so much Dr Ishtiaq ur Rehman

Doctor Ishtiaq ur Rehman is so good and so competent, very elegant, kind and understandable person. He will give you enough time as per your problems i am a big fan of his behaviour as well his treatment. The reason for this is that i was burnt when i was 3 years old. The rest got better with time but mark (scar) remained on my forehead. This mark was fairly prominent and felt so bad i was very upset because of this then i searched a lot of cosmetic surgeons in pakistan out of all this, i found the best Dr Ishtiaq ur Rehman orkazai. Then i contacted Dr Ishtiaq ur Rehman orkazai he looked at the mark on my forehead carefully. After seeing Dr advised Dermabrasion ( surgery) . Even i consulted the best indian doctor he suggested the best cosmetic surgeon in pakistan is Dr Ishtiaq ur Rehman orkazai . Now Dermabrasion ( surgery ) process is complete i am totally relax and so happy. For versatile plastic surgery, cosmetic surgery, burn surgery services he is the best doctor. I am very thankful to him May Allah give you the progress ameen.
