Mark Nesbitt was a National Park Service Ranger/Historian for five years at Gettysburg before starting his research and writing company. Living in Gettysburg has given him a unique “insider” perspective from which to write his popular Ghosts of Gettysburg series. He has authored over twenty books spanning several genres, including the paranormal, history, and true crime with a paranormal twist. Mr. Nesbitt has been seen on The History Channel, A&E, The Discovery Channel, The Travel Channel, Unsolved Mysteries, regional television shows, and heard on Coast to Coast AM, and regional radio. In 1994, he created the commercially successful Ghosts of Gettysburg Candlelight Walking Tours®.
