Dear friends, 

As you all know, I've been accepted by another company and will be resigning from my position this week. Let me say my sincere goodbye to all of you.

    For me, it's been a hard decision. I have been with you for the last four years and always appreciated the professional teamwork. It was the best period of my career so far. I learned a lot of things from you all. It was really a good opportunity to be part of this team. I am sure it will be difficult to forget all the experiences and relationships we have had so far. We will remain friends. My time is always available for you all. I do hope my new job has the same level of teamwork like I have had here.

    Thank you for those wonderful moments. Wishing you a successful career and life today and forever.

Best regards,

Brendan Scott
