Médecin très gentil et aimable, équipe sympathique et très professionnel. De les réceptionnistes aux médecins en passant par les locaux médicales rien a dire un plaisirs.

Mon mari et moi-même sommes patients du Dr Bagnoud et nous avons beaucoup de chance qu’il soit notre ophtalmologue. Il est très professionnel et sympathique. Il est bien organisé et il n’y a pas d’attente. Il va au bout des problèmes et il reste disponible tant que tout n’est pas réglé. Merci beaucoup à lui et à sa sympathie assistante.

Excellent centre ophtalmologique. Accueil chaleureux et professionnel, personnel à l'écoute et très compétent. Prise en charge rapide et efficace. Je recommande !
