Maggie reviewed I can’t thank booking surgery enough!

I can’t thank booking surgery enough!, first of all everything went easy and smoothly with my co ordinator David Turker, very helpful and because he’s been through it all before you felt you had all the information you needed! Secondly how amazingly my surgery went from pre op tests to post op care!, everything went perfectly and I’m 18 weeks post op and 76lbs down!, dr katar is a lovely friendly and talented man!, I would 100% recommend , thank you for giving me my life back!

Monika Jur reviewed Dr Yalcin is one av the best.

So happy with the treatment.

Dominique Roberts reviewed Completing part of my journey

This is my second time using BookingSurgery.Com, first was 12 months ago having a Gastric sleeve with Dr Tardu and this time having a 360 TT, Lipo, Muscle repair and arm lift with Dr Omer. Each and every staff member deserve a medal, they are so kind and caring and nothing is ever too much for them, they make you feel safe and well cared for. My coordinator David Turker has been fabulous answering all my questions and communicating with me throughout the process, again nothing has been too much trouble for him. A massive thank you to Dr Omer who really is such a lovely caring person, checking in on me regularly throughout my visit. Although only a week post op I’m completely overwhelmed by my results, they have far exceeded my expectations.. he truly is a genius! I genuinely cannot praise this company enough and have recommended them to a number of friends.

Mrs D Reilly reviewed Just back from my second procedure…

Just back from my second procedure through Booking Surgery with Penny River as my coordinator. First trip was gastric sleeve with Dr Ali Tardu at Optimed hospital and second trip was arm and thigh lifts with Dr Yalcin at Medistanbul hospital. I had the best experiences on both trips and could not fault a thing. From booking initially to arriving to doctor/nurse care to cleanliness to transfers. Everything went according to plan. I would never book with anyone else. This company go above and beyond for their patients.

Emily reviewed I had my surgery in January 2025 and it…

I had my surgery in January 2025 and it was great. All staff were friendly and would do anything for me. Whenever I asked for anything like pain killers etc I would have it within minutes. Bruce was my co ordinator. Himself and his brother went above and beyond to make my experience so smooth. Bruce supported me in Turkey and my family in the UK which is more than I could ask for. Thank you all for your help.

Emma reviewed This is my second time with booking…

This is my second time with booking surgery. First was with Ali tardu a year ago for a gastric sleeve, lost 9 stone in a year. He was amazing . I am travelling back today from medistanbal after breast uplift, implants and skin removal from my bra line with dr Omer . What an amazing team I had . Dr Omer was smiling all the time and asking what I wanted and if needed anything or had any questions . He visited most days after surgery . The nursing team and everyone else on the 4th floor were so caring, kind and helpful . Always around to help with a translator but most of the time there English was great and if they wanted they used google translate . The rooms are lovely and nothing is too much trouble. The hospital could do with a microwave that would make life a little easier with food as the food is terrible lol but right next door is a mall with lots of shops and a supermarket so it wasn’t the end of the world . There is a toaster and kettle with some basic supply’s for everyone . Hair dryer in the room and towels provided if asked for . I am back again in October and I feel in very safe hands . Thank you to my 2 coordinators David Turker and rossie Williams

customer reviewed Hair Transplant, Fantastic Service, Great Coordinator (Bruce Grayson)

Great service from initial contact and throughout the entire procedure, including the hight level of after care. Bruce Grayson the coordinator was fantastic, contactable to answer any questions prior to the trip, during and after once I returned to the UK. The hospital was very clean and modern, all the staff made me feel welcome.

Vicci reviewed My experience here was amazing

My experience here was amazing. The staff, coordinator Bruce Grayson and surgeon were all very attentive, they seriously couldn't do enough. The moment we got to airport we were met and taken to hospital, we filled all paperwork out and then had all pre op. The morning of the operation was seen by surgeon and went down 9.30am went down and was back by lunch time. I have never felt so taken care of. I ended up needing a blood transfusion, but again the team were amazing, told me there was a small charge but I mean you can't put a price on health and I felt so much better afterwards. The Room was cleaned twice a day they were so friendly, left the place gleaming, even the staff that brought us food 3 times a day really cared about their jobs. Cannot recommend them enough. My Breast reduction and Lift was the best decision I have ever made Dr Hakan Fatih Merev was superb 👌🏼 I would definitely go back to him.
