SAND SPRINGS, Okla. - Some would say he's "The King" of Charles Page High School.
Years ago, Frank Cooper traded in his time in the courtroom as an attorney for another room -- this time filled with teenagers.
The Sand Springs teacher was featured Tuesday on NBC's "Today," as an educator who uses his talents and a simple message to inspire his students. Not to mention he shows up with one heck of an Elvis impersonation.
Among the lessons Cooper shares with the teens who pass through his door, "KYP," which stands for keep your promise -- a message Cooper learned from his father.
And year after year, Cooper tells his kids, "You are important. I love you. And the joy of life is in the journey." Words his students remember years after they graduate.
