After carefully reviewing all of the entries and feedback, I have submitted this logo for your consideration. None of the current submissions seem to be rough enough or gritty enough. So I incorporated a look that expresses "the grit, the grime, the tough work, the struggle," and I decided it was perfect to use a mountain as the icon of what you do. The climb and reaching your peak is the goal of all who enroll.
Additional layouts to follow... I look forward to your feedback and reaction to my ideas.
The text is strong enough on its own to stand alone as well. So if you wanted an alternate logo or just your wordmark, you could certainly use this one.
(I would be happy to provide multiple files, so that you can have all of the variations on hand.)
