Dr. Constantinos was born in Lefkosia. As a young child, he showed a great love for animals. For this reason from a very early age, he made the decision to study to be a veterinarian.

He followed his dreams by entering the Veterinary School of the Aristotle University in Thessaloniki. After his basic studies, he continued in Thessaloniki his post-graduate veterinary studies on surgery, anesthesiology, and obstetrics of companion animals. Subsequently, he continued his postgraduate studies at the University of Utrecht in the Netherlands, and the Veterinary School of Edinburgh in the UK, on the fields of dog and cat surgery and pet internal medicine.

After completing his post-graduate studies he returned to Cyprus and became a partner at a veterinary clinic in Ayios Dometios, Nicosia. Twelve years later, in 2013, he established his own clinic, Staris Veterinary Clinic. 

Throughout his entire career, Dr. Staris has followed an array of specialized seminars, mainly abroad, but also in Cyprus. The seminars were on tissue surgery and orthopedics, dermatology, dentistry, anesthesiology, etc.

The need for constant education led him to participate in a three years post-graduate training course on small animal surgery. The training course is practical and highly specialized, organized in the UK by the British Small Animal Veterinary Association (BSAVA).

Dr. Staris and his wife, Yiola, live in Nicosia in a full house with their two children, and their three rescued pets, Orestis, their dog and Mikroulis and Felix, their cats.
