This letter is to inform you that I am resigning my position as assistant coach of the Tornadoes effective immediately. I am going to pursue my dreams and take the head coaching job with the Company Name in the International League. It is the kind of job I have wanted my entire life and I am going to take the opportunity.
I want to take this moment to thank you sincerely for the opportunity you and Head Coach Pastor have given to me over the past four years. Without your guidance and belief in my abilities, I would have never received the exposure I needed to get the chance to be a head coach. Since I know that Coach Pastor will be in Company Name for a while, I realize that my best chance to become a head coach is outside of the Tornadoes organization.
I have already spoken to the team and Coach Pastor and they have all wished me well. If you need to contact me for any reason at all, you can call me at 000-000-0000 or email me at firstname.lastname@example.org. Thank you again for the opportunity.
