I was very interested to see your advertisement for ХХХХХ Program Assistant at your website. I am actively seeking an assistant opportunity in a demanding, fast-paced multi-tasking office. My work experience has equipped me with a multitude of skills, and I would like to continue my growth at your company. My resume is enclosed for your review.
Throughout my career I have demonstrated for my employers an exceptional facility for meeting organizational objectives and demands. In addition to my organization and assisting skills, I am able to handle multiple tasks at once. I am certain I would prove to be an asset at your company as well.
If my abilities meet the needs of your company, I would greatly appreciate the opportunity of speaking with you personally at your earliest convenience. Thank you for your time.

I look forward to hearing from you soon.

Sincerely,
