Gelehrter created the persona of Penny Dreadful the witch in an effort to revive the concept of a horror movie host on Boston-area television.

The show, Penny Dreadful’s Shilling Shockers, began production in August 2005 and premiered on local cable in January 2006.

[3] 'The Dreadful HallowGreen Special,' a made-for-TV movie which Gelehrter co-produced and co-hosted with Larry Underwood aka TV horror host Dr. Gangrene, was nominated for a regional Midsouth Emmy Award in 2011.

[6] On March 16, 2019, 'Shilling Shockers' director Rebecca Paiva was inducted into the Horror Host Hall of Fame in the "Behind the Screams" category.

[8] Penny Dreadful XIII is a regular guest at conventions such as HorrorHound in Indianapolis, Indiana; Monster Bash in Pittsburgh, Pennsylvania; [9] and Rock & Shock in Worcester, Massachusetts.

Terror at Collinwood explores Dark Shadows’ storylines and characters, examining the show’s important place in gothic horror and pop culture history.

The podcast also features in-depth discussions and interviews with fans, creators, crew, and cast members including David Selby, Kathryn Leigh Scott, Lara Parker, Marie Wallace, and more.

This was prompted by an anti-transgender ballot question in Massachusetts at the time which would have prohibited trans people from using the restroom which matched their gender identity.

Through the bios, Gelehrter introduced a new vampire villain called the Crimson Countess in an effort to add more distinct horror-themed elements to the Masters of the Universe canon.

Starting in 2019, Gelehrter and Eric Marshall began writing official packaging bios for Super7's ThunderCats Ultimates action figure line.
