Prof
Hi, I'm Cella, and I’m living in Bali, Indonesia. I’d like to share an honest review based on my experience of finding a medical coordinator, a doctor, and a hospital for my case. I was recently diagnosed with an ovarian cyst and stage 4 endometriosis, which required surgery as soon as possible. I was initially hospitalized in Bali, but the doctor there suggested I look for a better-equipped hospital as they didn’t have the necessary facilities to perform my surgery. It wasn’t easy to find the right care on a small island like Bali. Thankfully, my best friend helped me connect with a medical manager from Bookimed. That’s how we found Alisher, the medical manager and Prof. Dr. A Cem Iyibozkurt from Florence Nightingale Hospital in Istanbul. We arranged an online consultation with the doctor, which was free of charge, I already have all my medical records and MRI results before an online consultation, I’ve prepared everything to speed up the process. and within a week, they scheduled my laparoscopic robotic surgery. Alisher did an excellent job coordinating everything, and I couldn’t be happier with him. Prof. Dr. Cem Iyibozkurt is an amazing doctor, highly experienced, and well-known for his expertise in the field. The hospital itself was fantastic—the nurses and staff took great care of me. I’m really grateful for the smooth process, and I highly recommend them to anyone who may be in a similar situation and looking for this kind of care and has similar situation as mine.

We felt fully confident knowing we were in the hands of one of the best in his field
World-Class Neurosurgical Care and Compassion We are profoundly grateful for the exceptional care provided by Professor Ilhan Elmaci. His expertise, professionalism, and compassionate approach were evident from our very first meeting. Professor Elmaci performed the surgery to remove a medulloblastoma with extraordinary precision and care, and we felt fully confident knowing we were in the hands of one of the best in his field. Beyond his remarkable surgical skill, Professor Elmaci took the time to explain each step of the process with clarity and patience. He was always available to answer questions and offer reassurance, treating both the patient and our family with deep empathy and respect. A heartfelt thank you to Coordinator Alisher, who supported us at every step. He was always responsive, attentive, and truly dedicated to the patient’s well-being. From organizing the transfer and handling all special requirements to keeping the family updated and arranging medical needs, he made a difficult time much more manageable. The hospital staff was professional, kind, and caring throughout. We deeply appreciate the high level of expertise and personal attention that made all the difference in this journey.

Her level of empathy was touching
My request was for a specific treatment for my condition, which I believe was triggered by COVID or vaccine-related complications. The treatment itself is relatively new and not widely available; however, the doctor Faturanız Hazırdır was open to considering my request, which was a decisive factor in choosing this hospital. Her level of empathy was touching. When I arrived, I received outstanding support from Aliser Durdiyev, who coordinated the entire process — from reception and medication procurement to scheduling the treatment. None of this would have been possible without Hanna Karvatska, who connected all of us who has deep personal and professional connection with people here, and I’m deeply grateful to her, Alisar, and the doctor for their support and professionalism. And special thanks for the empathy from all three people, the teamwork they created to get me what we all believe could be the best treatment.
About Bookimed service
Hanna is a remarkable individual with a big heart, dedicated to connecting patients with top-tier doctors and medical professionals across various countries. Her extensive network ensures that every partner and connection goes the extra mile to meet patient needs without hesitation. Aliser is a young but already experienced medical advisor. I was positevley surprised with approach. One of the most critical aspects of arranging medical treatment abroad is navigating logistics in an unfamiliar country. This is where Aliser's proactive approach truly stands out. His exceptional energy, personal connections, and unwavering curiosity to find the best solutions were decisive factors in my positive experience. Together, Hanna and Alisar helped to oerganise care and coordination, making the complex process of international medical treatment seamless and patient-focused.

I recommend from the bottom of my heart
We were diagnosed with internal and external hydrocephalus in a newborn. While searching for clinics, I accidentally came across the Bookimed platform. They immediately responded to my request and assigned a personal medical coordinator of the platform Olga Romaniuk. Very responsible, always in touch, she competently selected us a clinic florence ningtingale hospital and signed us up for an online consultation with Professor Ilhan Elmachi. After that we were assigned a manager of this clinic for online consultation Alisher, (by the way, he speaks several languages, including Turkmen, which was a big plus for us). Alisher is also very responsible, always in touch, selects convenient for us time for consultation, helped us to hold an online meeting without delays and interruptions. I am very satisfied with the work of Elmachi docor. All questions were answered. Special thanks to Elmachi's translator 🫶🏻. I recommend from the bottom of my heart
