Holzer, managed and treated a large number of cases for many years, involving both benign and malignant diseases of the thyroid, adrenal glands and diseases of the parathyroid glands.
In parallel with his specialization in Endocrine Surgery, he attended the Postgraduate Program of the Aristotle University of Thessaloniki, with the subject of Health Statistics and Data Analytics, which he completed with honors, obtaining the title Master of Science (MSc). His rich writing work and his uninterrupted involvement in the education of students at the University Clinic Marburg paved the way for his appointment as Associate Professor (PD Dr. med.) at the University “Philipps-University Marburg”. He continues his academic work with responsibility and undiminished enthusiasm at the University Clinic of Marburg, participating in the teaching and supervision of doctoral theses of the University students.
