The management team

Kallirroe Fragkou / CEO - Pharmacologist
Her comprehensive coursework in the School of Pharmacy and Biomedical Science provided her with invaluable laboratory research skills, leading to her employment as a Research Assistant in the Immunology Department at the University of Sussex, Brighton, in 2004. Her professional journey also includes a role as a medical sales representative, specializing in Remynil and Topamac, for JANSSEN-CILAG, a multinational pharmaceutical company with a subsidiary in Greece.
However, her career in pharmacology had to be put on hold due to a heart-wrenching experience involving her daughter’s health. Her daughter, Marieva, was diagnosed with malignancy at just one year old and embarked on a courageous battle for her life. Over the course of five years, Kalliroe Fragkou confronted her own struggles with depression and anxiety disorders. Discovering the inner strength to overcome these challenging phases became a transformative experience, equipping her with newfound resilience.
Kallirroe Fragkou, characterized by her unwavering determination, inherent compassion, and a bright spirit, was inspired to channel her life experiences into helping others grappling with addictive behaviors and mental health issues. This inspiration led to the creation of Marieva’s Healthcare Center. Today, Mrs. Fragkou possesses over five years of profound expertise in providing one-on-one treatments to those in need.
