Η Αθανασιάδου Τραϊάνα είναι Ψυχολόγος με προσέγγιση γνωσιακής Συμπεριφορικής κατεύθυνσης. Εχει εξειδίκευση στην Σεξουαλικη Υγεία, τις ψυχοσεξουαλικες διαταραχές και την ταυτότητα Φύλου. Ακολουθεί μια συνθετική προσέγγιση καθώς πιστεύει πως ο κάθε άνθρωπος είναι ξεχωριστός και για να αναπτυχθεί ο Αληθής εαυτός του χρειάζεται να φωτιστεί η ιδιαιτερότητά του.

Το άγχος, ο φόβος, η θλίψη είναι συναισθήματα που μοιραζόμαστε όλοι, ωστόσο για τον καθένα το κάθε συναίσθημα ξυπνα ένα προσωπικό "αφήγημα" ζωής.

Πιστεύει πως στην καρδιά της θεραπείας βρίσκεται ένας χώρος ζωντανός, ευέλικτος, όπου το αληθινό συναντά το δυνατό. Εκεί, μέσα σε μια σχέση που κρατά αλλά δεν εγκλωβίζει, ο εαυτός δεν χρειάζεται πια να κρύβεται—γεννιέται ξανά, ελεύθερος. 

Πιστεύει πως συχνά κάνεις γίνεται το τραύμα του και η θεραπεία επέρχεται με το να καταφέρει να δει τον εαυτό του ως ένα όλον που έχει και τραύματα ωστόσο μπορεί να τα φροντίσει και κα τα αγκαλιάσει. 

Από τα φοιτητικά ήδη χρόνια υπήρξε ενεργό μέλος σε πολλούς φορείς Ψυχικής Υγείας. Έχει εκπαιδευτεί σε ξενώνες του Ψυχιατρικό Νοσοκομείου Αττικής (Ψ.Ν.Α) με χρονια πάσχοντες ασθενείς. Έπειτα ασχολήθηκε με την Ψυχική Υγεία Γυναικών στο ειδικό Νοσοκομείο Γυναικών της Α' Πανεπιστημιακής -Αιγινήτειο Νοσοκομείο. Εκπαιδεύτηκε στο Ειδικο Ιατρειο Ψυχοσεξουαλικων Διαταραχών στην Α' Πανεπιστημιακή Κλινική ενώ μερι και σήμερα βρίσκεται στην Μονάδα Συμβουλευτικής Φοιτητών του ΕΚΠΑ.

Την περίοδο της covid 19 συμμετείχε ενεργά και στελέχωνε την Γραμμή Ψυχοκοινωνικης Υποστήριξης για την πανδημια ενώ συμμετείχε σε πολλές δράσεις προαγωγής Ψυχικής Υγείας. Σπούδασε στο τμήμα Ψυχολογίας Παντειου και έπειτα Παρακολούθησε πρόγραμμα ΜΠΣ στην Ιατρική Σχολή Αθηνών. Είναι μέλος της Ελληνικής Εταιρίας Γνωσιακής Συμπεριφορικης Θεραπείας.

Έχει μετεκπαιδευτεί στην ψυχοπαθολογία και στην Αναλυτική προσέγγιση Ομαδικής θεραπείας.

Πιστεύει πως η ομάδα μπορεί να αποτελέσει ένα ασφαλές πεδίο γέννησης του εαυτού μέσα από αλληλεπιδράσεις ανθρώπων που εντέλει δημιουργούν ένα όλον αποτελούμενο από πολλά "ολόκληρα" που συνθέτουν έναν χώρο θεραπείας και προαγωγής των σχέσεων με τον εαυτό και τους άλλους.

Η Βασιλική Δημαρά είναι Ψυχολόγος και εκπαιδεύεται στην ψυχοθεραπεία στο Ανοιχτό Ψυχοθεραπευτικό Κέντρο (ΑΨΚ).

Έχει εργαστεί σε νοσοκομειακά και κοινοτικά πλαίσια ψυχικής υγείας, καθώς και σε δομές που αφορούν τις νευρογνωστικές διαταραχές, αποκτώντας εμπειρία στην υποστήριξη και τη συνοδεία ανθρώπων με διαφορετικά αιτήματα και μορφές δυσκολίας.

Στο θεραπευτικό της έργο δίνει ιδιαίτερη έμφαση στη διαμόρφωση ενός σταθερού και αξιόπιστου πλαισίου, όπου το άτομο μπορεί να εκφραστεί με τον δικό του ρυθμό. Η εργασία εξελίσσεται μέσα από την προσεκτική κατανόηση της εμπειρίας του κάθε ανθρώπου και τη σταδιακή διερεύνηση όσων τον απασχολούν.

Το ενδιαφέρον της για τη φιλοσοφία επηρεάζει τον τρόπο που προσεγγίζει την ψυχοθεραπεία, ως μια διαδικασία που αφορά όχι μόνο την κατανόηση των δυσκολιών, αλλά και τη σχέση του ανθρώπου με τον εαυτό του και τους άλλους.

Ασχολείται με ζητήματα άγχους, σχέσεων και αυτοεκτίμησης.
