Dear fellow Rotarians of D 9400,
                                  
In those most trying moments of humanity, I sincerely hope that all stay healthy and safe regaining slowly normal rhythms of life. As Covid-19 pandemic spread around the globe we found ourselves in a world transformed. Despite the peripeteia our Organization moved very effectively towards the new reality. We invented new ways to stay connected, continue our great social offer to our communities, and join our efforts for a better world.
                          
New approaches to our organizing principles do not threaten us, we consider them as a real challenge. In this transition period we are the pioneers of a new reality and adopt innovations in shaping our future. We are ready to open opportunities, create more paths to leadership, amplify our conversations to diverse voices, and adapt how we operate to the new circumstances.                            
                                   
Now more than ever we must prove that Rotary is an organization inclusive of all cultures, experiences, and identities.                           
‘’We all have a responsibility—men and women in every club and every district in the Rotary world— to help our organization diversify and grow so that we can remain relevant for future generations.” as  RI President Mark  Maloney states.                               
I address my warmest wishes to DG 2020-21 Annemarie Mostert, to the District officers and to all the members of D 9400 for a productive Rotary year full of success and significant achievements.                           
Working as a solid team we will prove that overpassing difficulties we will open opportunities for broadening Rotary horizons and reaching excellence.                           
Yours in Rotary
