Ο Αθανασόπουλος Νικόλαος είναι Γαστρεντερολόγος - Ηπατολόγος - Επεμβατικός Ενδοσκόπος και διατηρεί ιδιωτικό ιατρείο στον Πειραιά. Σπούδασε στην Ιατρική Σχολή του Εθνικού και Καποδιστριακού Πανεπιστημίου Αθηνών. Πραγματοποίησε την ειδικότητα της Γαστρεντερολογίας στο Γενικό Κρατικό Νοσοκομείο Νίκαιας. Έχει πλήρη εξειδίκευση και μετεκπαίδευση σε όλες σχεδόν τις πτυχές της ειδικότητας. Έχει μετεκπαιδευτεί στον τομέα της επεμβατικής ενδοσκόπησης στο Ευρωπαϊκό Ενδοσκοπικό Εκπαιδευτικό Κέντρο του Πανεπιστημιακού Νοσοκομείου της Ρώμης "Universita Cattolica del Sacro Cuore" και στο περίφημο Ενδοσκοπικό Κέντρο Εκπαίδευσης των Βρυξελλών (πολυπεκτομές, αντιμετώπιση οξείας αιμορραγίας ανωτέρου και κατωτέρου πεπτικού, αντιμετώπιση περιπτώσεων ενσφήνωσης βλωμού, τοποθέτηση ενδοσκοπικής γαστροστομίας, οισοφαγικών και εντερικών stent, ERCP). Επίσης, διαθέτει σημαντική κλινική εμπειρία στις κινητικές παθήσεις του γαστρεντερικού συστήματος, καθώς ο ιατρός ήταν αναπόσπαστο μέλος του Εργαστηρίου Κινητικών Διαταραχών της Γαστρεντερολογικής Κλινικής του Πανεπιστημίου Αθηνών. Μακρόχρονη και βαθιά είναι η εμπειρία και η γνώση που έχει αποκτηθεί στην Ιδιοπαθή Φλεγμονώδη Εντερική Νόσο, καθώς είχε την τύχη να θητεύσει κατά τα χρόνια της ειδίκευσής του στο τριτοβάθμιο ειδικό κέντρο για φλεγμονώδη νοσήματα του Γενικού Νοσοκομείου Νίκαιας, ένα από τα ελάχιστα κέντρα αναφοράς ΙΦΕΝ (ελκώδης κολίτιδα και νόσος Crohn) στη χώρα μας. Ο ιατρός έχει επίσης μετεκπαιδευθεί στην κλινική ηπατολογία, έχοντας παρακολουθήσει τις εργασίες του 4ου Σχολείου Κλινικής Ηπατολογίας κατά το ακαδημαϊκό έτος 2010 - 2011. Η συνεχής και άσβεστη επιστημονική και ερευνητική του δίψα αποδεικνύεται από το πλήθος δημοσιευμένων εργασιών, ανακοινώσεων, διαλέξεων, ομιλιών σε ελληνικά και ξένα περιοδικά και συνέδρια, καθώς και από τη συμμετοχή σε διεθνείς πολυκεντρικές μελέτες για την αναζήτηση και έρευνα νέων φαρμακευτικών θεραπειών που αφορούν κυρίως στις νόσους της ελκώδους κολίτιδας, νόσου Crohn και ηπατίτιδας B και C. Το μεγαλύτερο όμως παράσημο στην ως τώρα ζωή και καριέρα του θεωρεί ότι είναι η ίδρυση και συμμετοχή σε μια ανθρωπιστική οργάνωση, που ονομάζεται "ΔΩΣΕ ΕΛΠΙΔΑ", που ως στόχο έχει την δωρεάν και ανιδιοτελή παροχή βοήθειας σε χρόνιους πάσχοντες από νεοπλασματικά και μη νοσήματα. Αποτελεί ιδρυτικό στέλεχος και είναι αντιπρόεδρος του οργανισμού από το 2010.
