About me

I graduated from Izmir Dokuz Eylul University with the orthopedics branch. After I graduated, I carried out some

studies focusing on especially on

joint and cartilage surgery and stem cells. In this, I worked with many professional and amateur sport clubs. Also,

I worked on joint replacement surgery

for further aged people. Approximately, I achieved 10 thousand people who took knee and hip replacement

surgery from me. I attended to many international conferences about joint and cartilage surgery. Now I start

Ortocare Clinic for orthopedics and health center. In here, I treat my patients using the most advanced

technologies in the world, such as foot health centers, electromagnetic therapy, cryocabin therapy, backup

therapy and stem cell therapy. In our clinic, I continue to my work on non-surgical treatments, especially antiaging

treatment, and to eliminate pain problems in patients. On top of that, I also carry out some post-operative

rehabilitation and medical plates exercises.
