You may have had a “guide” in completing your degree. Perhaps a friend gave advice at a critical juncture. You may have had a colleague at another campus who responded with wisdom to an email where you voiced a struggle. There are varying degrees of Mentoring from Coach to Pen Pal. We will call your role an E-Mentor and ask “Why Mentor?”
