Dr. Mehran Ebrahimi 
Born in 1972 in Tehran.
Graduated in medical practitioner at Respiratory, Skin and Food allergy
in PHD degree at Tehran University of Medical Sciences.
Also I have (8) years experiences in Asthma treatmen, bronchitis inflammation ،
respiratory infections and assessment and control at Infections in immunocompromised patients.
In addition to medical activities, I recently started doing Aikido as a student of two great masters
Mr. Hassan esfahani and Mr. Reza Kafouri.
It is worth mentioning that not only did I learn martial arts from these dear masters,
but they are also symbols for me morally and characteristically.
