Help composing a chain letter for a company goodbye?

Question

I want my letter to be very professional yet heart warming lol. I know this sounds lame but I really do love the company I'm with. I just was offered an opportunity I couldn't pass up. this is what I have so far please re-write one to be more professional sounding that Includes what I have already written to an extent. Thanks!!

Today is my last day with BLANK BANK,

and I just want to say what a wonderful experience this has been. I have met some really amazing people in this company and can honesty say I am sad to be leaving. The things I have learned here since I have started at my home branch Belvidere-Beloit Rd will stay with me no matter where I go. I have gained knowledge and integrity that I have this company to thank for. Little did I know I would enjoy being apart of banking so much. I really would like to give a special thanks to BLANK AND BLANK, I am lucky to have worked under such great management. There are so many other people with BLANK that have special thanks for, but there are to many to name. I sincerely hope that my path will cross with BLANK again some day. Thank you every one! The last year and 2 months spent with this company have been great.

Answer 1

Sadly, today is my last day here at Blank and Blank and I want to say to all my friends and colleagues, what a wonderful and rewarding experience it has been working with all of you.  My time here at the Belvidere-Beloit Rd branch has given me a chance to grow, learn,   succeed and truly come to love what I do.

I am fortunate to have worked for a great management team and I have learned and benefited from working with each and every one of my colleagues.  While the people who have influenced my career are to numerous to name, I want to say, thank you.  You have given me confidence to take the next step and accept new challenges.  Please know that any measure of success I have in the future is directly attributed to each and every one of you.

Over the past year, I have come to see this branch as my second home and all of you as my second family and I will miss seeing you each and every day. Unfortunately, every new beginning starts with an ending.  While my time here at Blank and Blank is drawing to a close, the friendships I have made will last a lifetime.  I know that personally our paths will cross again and I hope that perhaps someday, professionally as well.  Again, thank you, from the bottom of my heart and my sincerest wishes for continued success and prosperity here at Blank and Blank.
