Ο κ. Χαλιάσος ήταν ιδιαίτερα επεξηγηματικός και καθησυχαστικός. Αφιέρωσε χρόνο πριν το ραντεβού προκειμένου να μελετήσει τις εξετάσεις, εξήγησε με σαφήνεια τα αποτελέσματα και μας καθοδήγησε με ηρεμία και επαγγελματισμό. Το ραντεβού αφορούσε το 2 ετων παιδι μας οπότε είχε ιδιαίτερη βαρύτητα για εμας. Τον ευχαριστούμε θερμά για τη στήριξή του.

O κ. Χαλιάσος έδειξε εξαιρετική φροντίδα και επαγγελματισμό κατά τη διάρκεια της θεραπείας μου για τον αυχενικό πόνο. Από την πρώτη στιγμή ένιωσα ότι βρισκόμουν σε καλά χέρια. Ο γιατρός μου εξήγησε με λεπτομέρεια τη διάγνωση και τα βήματα της θεραπείας.Η κατάστασή μου βελτιώθηκε αισθητά μέσα σε λίγες εβδομάδες. Ο πόνος μειώθηκε σημαντικά και επανήλθα στις καθημερινές μου δραστηριότητες
