I was totally caught by surprise when Dean Theodore Lyras informed me that I would receive a symbolic scholarship from Deree for my postgraduate studies at the LSE.

Q.: What do you miss most from your days at Deree?

The high energy levels and lively atmosphere in the “oasis” of the ACG campus.

The gym!

Dean Theodore Lyras – He was more than a professor; he was my mentor, inspiring me to do my best and helping me build my self-confidence and unleash my potential.

Q.: After graduation, have you maintained a relationship with your school and classmates?

We remain close friends with most of the “parea” which used to “occupy” the right corner of the cafeteria. During the last alumni reunion, it was great to see many classmates; it felt as if “a day hasn’t passed” despite the fact that we had graduated more than a quarter of a century ago!

Deree inspired and enabled me to unleash my potential and build my self-confidence.

Grasp the opportunities offered at Deree to enrich your knowledge, develop your skills, expand your networks and build solid foundations for your professional career. Above all, though, develop your personality and make sure you enjoy the Deree experience!

Q.: Where do you get your inspiration from?

There are role models who inspire me for their values, achievements and impact towards great causes, but nothing compares to my daughters, who are a precious source of inspiration, boosting my energy levels whenever I run dry.

Q.: What is your motto in life?

“You can never cross the ocean unless you have the courage to lose sight of the shore.”
