Mark Rosendorf 's writing is based on the personalities and experiences he has come across throughout his life, coupled with his own wild "if only I could do that" imagination. He is the author of the young adult series, The Witches of Vegas. He is also credited with The Rasner Effect series, a suspense/thriller trilogy published between 2009 and 2012.

Mark has also moonlighted as a professional magician. Today, he teaches magic and Illusion to his students in order to teach teamwork while developing their confidence.

Having accomplished his goals of becoming an author, Mark decided on an early retirement from writing. Then, one night, at two a.m., a new and unique story shot into Mark's brain like a lightning bolt, screaming for him to write it. Mark found himself spending several nights taking notes on the characters and their stories. That is how The Witches of Vegas series was born.
