From the bottom of my heart, I thank everyone
From the bottom of my heart, I thank everyone. Memorial Hospital is not a hospital, it is a home where staff members look after a patient with a warm heart. My mommy makeover included a tummy tuck, breast work, and liposuction on two areas, and it was important that Dr. Demir personally checked on me after the surgery. The only thing that could be better is if nurses spoke more English, especially for post-op care. The clinic is easy to reach. I am very grateful.
From my bottom heart I would like to thank you everyone,start from whatsapp consultant, clinic coordinators, nurse, hotel and big thank you a Dr.Demir.All of you were amazing in every way.I would choose you again and again.Memorial hospital is not only a hospital, it is a home where all staff members look after a patient with warm heart.I am very greatful for everything.❤️❤️❤️
Nurses at the hospital could speak english more especialy post- opp care.

I'm certainly glad I made this decision
If you're considering a comprehensive female check-up, I wanted to share a little about my process. From the initial coordination, everything felt very well-organized and straightforward. I felt very supported. The clinic itself has a professional and calm atmosphere, which helped me feel at ease upon arrival. The medical team and my surgeon were particularly attentive and thorough, taking the time to explain each part of the process and making sure all my questions were answered. The care I received from everyone on the staff was consistently thoughtful and considerate. I'm still processing everything but I'm certainly glad I made this decision.

The surgeon and the clinic itself were excellent
The possibility of breathing issues was my primary concern going into this. And honestly, that has been the biggest challenge in recovery so far, with one nostril constantly feeling stuffed. My surgeon performed a closed rhinoplasty. Everything is still very swollen along the bridge, but I can already see that my nose tip appears more refined, which is a great sign. The surgeon and the clinic itself were excellent. The general staff were great, though post-op instructions could have been a bit more explicit. I'm satisfied with the medical care I received so far
Dr. Erol is an amazing doctor, his work was amazing he truly listened to my request and expectations and he was really patient and reassuring. The medical assistance team as well, they really took good care of me, they were present when i needed them.
post-op instructions could’ve been explained better

Basically, I think the service was excellent
Basically, I think the service was excellent. I liked everything about the service and it was very comfortable, so I only have positive things to say. Everything was nice. While I believe that in every situation there can be improvement, I honestly cannot think of anything specific that could be done better right now. The clinic should just keep doing what they’re doing because the whole process was handled so well from the beginning.
Basically, I think the service was excellent. I liked everything about the service. It was comfortable so you know I just have everything positive to say about it.
I know, but in every situation, there can be improvement. I cannot think about anything that I can say that I can see could be improved right now, but I can say that you must keep doing what you’re doing because everything was nice.
