Οι μεταπτυχιακές του σπουδές στο Εθνικό και Καποδιστριακό Πανεπιστήμιο Αθηνών αφορούν την πρόληψη και την προαγωγή της ψυχικής υγείας. Όσον αφορά την ψυχοθεραπεία, έχει εξειδίκευση στη Γνωσιακή – Συμπεριφορική ψυχοθεραπεία (Ινστιτούτο Έρευνας και Θεραπείας της Συμπεριφοράς, πρόεδρος Καλαντζή-Αζίζι Αναστασία, Ομότιμη Καθηγήτρια Κλινικής Ψυχολογίας, Πανεπιστήμιο Αθηνών) και στη Συστημική – Υπαρξιακή ψυχοθεραπεία (Εκπαιδευτικό Κέντρο Συστημικής και Υπαρξιακής Ψυχοθεραπείας, πρόεδρος Καραγιάννης Δημήτρης, ψυχίατρος – ψυχοθεραπευτής). Η Γνωσιακή – Συμπεριφορική θεραπεία βοηθάει τον άνθρωπο να κατανοήσει και να επιλύσει τα διάφορα συμπτώματα (συμπτώματα κατάθλιψης : άσχημη διάθεση, απώλεια ενεργητικότητας, ανηδονία, αρνητικές σκέψεις κ.ά. και συμπτώματα άγχους : κρίσεις πανικού, ψυχαναγκασμοί, ψυχοσωματικά κ.ά.). Η Συστημική – Υπαρξιακή Θεραπεία συμβάλλει στο να κατανοήσει το άτομο τα προβλήματα σχέσης και οικογένειας που δημιουργούνται καθώς εντοπίζει τα λάθη που το ίδιο κάνει στην αλληλεπίδραση και στο πώς σχετίζεται με τους άλλους ανθρώπους, συνδέοντας παράλληλα πώς ο ίδιος έχει επηρεαστεί από την οικογένεια στην οποία μεγάλωσε. Η Υπαρξιακή Ψυχοθεραπεία κινητοποιεί τον άνθρωπο να αξιοποιήσει τις δυνατότητές του, να τις εξελίξει σε ικανότητες και να βιώσει ολοκλήρωση και ευχαρίστηση στη ζωή του.
