Congratulations

On behalf of everyone here at Kingsway Travel Agency I would like to congratulate you on your MBA.

It’s so great to hear from you. It’s good news that you have passed your MBA and to hear that without the experience you had working with us you couldn’t have done it. It was wonderful to work with you because you are very intelligent and have a good business brain (better: business mind). It was nice to work with you and being helpful to you was easy because you are an extremely hard worker and also polite and friendly.

I’ll give your best wishes to everybody who knows you here in Kingsway. Louise is still working here. I think she will be happy of hearing from you.

I wish you the best for your future and I hope you can have some holiday and enjoy it. I hope you can enjoy a vacation soon.

Take care and I hope to hear soon from you.

Best wishes

Kingsway Director
