I have been struggling all my life with my weight. After a ton of research, I have found the most wonderful doctor: Professor Dr. Hasan Altun. Him and his team are very welcoming, very accommodating and top of the line professional. From the first day I decide to have bariatric sleeve surgery to check-up to surgery itself and hospital stay. Everything went very smoothly and pain free. I am eternally grateful to him and his wonderful team which includes his sidekick doctor (Phd), amazing assistant, top of the line dietitian, ton of nurses and probably even more people behind the scene. His team is always in contact with me even though I live thousands miles away from them. They reply every question immediately. 100% recommended and I am eternally grateful.
