Έδειξε ιδιαίτερο ενδιαφέρον όχι μόνο στην πρόβλημά μου αλλά και σε μικρά ίσως ασήμαντα πράγματα όπως μου τηλεφώνησε αν βρήκα το ιατρείο του επειδή είχα καθυστερήσει 5 λεπτά, με συνεχή επικοινωνία.

Ο γιατρός με άκουσε, απάντησε σε όλες μου τις ερωτήσεις και με κατηύθυνε καταλλήλως, ενθαρρύνοντας με να επικοινωνήσω περαιτέρω μαζί του. Παρόλο που θα μπορούσε ως επαγγελματίας να εκμεταλλευτεί την ανησυχία μου με ανούσιες και ακριβές εξετάσεις, δεν το έκανε και είμαι ευγνώμων γι'αυτό. Τον ευχαριστώ για όλα

Εξαιρετικός γιατρός, ήρεμος, ευγενικός και πολύ κατατοπιστικός. Μου εξήγησε τα πάντα αναλυτικά και με έκανε να νιώσω άνετα και ασφαλής. Πολύ ευγενική και εξυπηρετική και η βοηθός του. Μια πραγματικά πολύ θετική εμπειρία.
