This tribute is from Keith Rocci:

Mr. Casteel was the best photographer I have ever met!  The guy could take amazing pictures.  My passion for photographer and video was created from him.  My success as a university professor is a direct result of his mentoring.  He was my friend, my mentor, and someone I admired.  A great educator who influenced many of us that were not part of the crowd.  He was also a graduate of Buena High School, so he was one of us.
