My Personal Profile Would you please correct sentences?? I was born and raised in kouhdasht, When I started high school I moved to Khorramabad for study at a boarding school called "Imam jafar" that was in a special area of the city called "Koroush" . At first year of high school I had a very nice and interesting Physics teacher that encouraged me to become a Physician!! and now I am a mechanical engineer just because of physic!! I am working for big company named "L.O.R.C" for 8 years and It's located in Lavan Island at the south of Iran in Persian Golf. These days I am the head of Machinery Maintenance Office.
