Christos graduated with the degree of diagnostic imaging operator in 1999. After few years of practice at the department of diagnostic imaging of public hospitals in Athens he followed interesting seminars about the decrease of radiation dose and increase imaging quality with computed tomography. His love for animals were the goal for leaving human diagnostic imaging and improve the knowledge and quality of advanced diagnostic imaging examinations in veterinary medicine.
