[Subject: Notice of Resignation]
Mr. Summers,
I'm writing to notify you that I will be resigning from my position at the Outreach Center, and my last day of employment will be October 31.
I appreciate the support I've been given during my time here, but I feel this decision is for the best. I would be happy to help with the transition in any way that I can during my remaining time with the center.
Respectfully,
Kate Freelander
