Goddess Athena apart from only having here owl... she had many other symbols, of of them was the olive leaf. I've created an olive wreath symbolizing the C -coach- as it also brings out the Greek in your name and centered the letter A -athena-... so we can have a pictorial mark and a letter mark logo -AC-...
Appreciate the great ranking! I'm going to take this up a notch. Make the symbol more compact... so it can be even used as a favicon for your site. Will be uploading in a bit.
