Έκανα το ραντεβού επειδή είχα ερωτήσεις σχετικά με μια αιματολογική μου εξέταση. Ο κ. Κουτσόγιαννος απάντησε όλες μου τις ερωτήσεις και έδειξε ενδιαφέρον για την περίπτωση μου. Μάλιστα, επειδή μένω στο εξωτερικό, έγραψε ένα σημείωμα για τη γιατρό μου εξηγώντας τις παρατηρήσεις του.

My wife and I felt comfortable with Dr. Katsogiannos from the moment we arrived at his surgery. He thoroughly checked the Ultrasound scan results of our thyroids, the past history and recommended an FNA with 2 known specialists. He also gave us a short insight into his professional background and that he worked for over a decade in Sweden. We can recommend Dr. Katsogiannos to anyone looking for an Endocrinologist.

Εξαιρετικός επαγγελματίας με προσεκτική και αναλυτική προσέγγιση. Από την πρώτη στιγμή μου ενέπνευσε εμπιστοσύνη. Ευγενικός και επεξηγηματικός, αφιέρωσε χρόνο να απαντήσει σε όλες μου τις απορίες. Τον συνιστώ ανεπιφύλακτα

Είχα την τύχη να επισκεφτώ τον Κ. Kατσογιαννος και η εμπειρία μου ήταν απόλυτα θετική. Από την πρώτη στιγμή, με έκανε να αισθανθώ άνετα και έδειξε μεγάλη προσοχή και σεβασμό στις ανησυχίες μου. Η διάγνωση ήταν ακριβής και η θεραπεία που πρότεινε απολύτως αποτελεσματική. Εκτός από την επαγγελματική του γνώση, ο Κ, Κατσογιαννος ξεχωρίζει για την ανθρωπιά και τη φροντίδα που δείχνει στους ασθενείς του. Σίγουρα θα τον προτείνω σε όποιον χρειάζεται ιατρική φροντίδα. Ευχαριστώ για τη βοήθεια και τη φροντίδα σας,
