About Kirk

Kirk Geller, Staff Writer for Global Gaming Insider, has worked in journalism for over five years and originally began covering all things gambling in early 2024. Having grown up in New Jersey prior to residing in Las Vegas, Nevada, Kirk has been on-site for some of the most notable developments in gaming, including growth for iGaming and sports betting.

Whether it’s covering the NFL, NBA, NHL or MLB, Kirk has always had a love for throwing himself into the deep end of professional sports, but has certainly become engrossed in the latest gaming innovation for the better part of two years. As a Staff Writer, Kirk covers news surrounding traditional casinos, iGaming, suppliers and, of course, sports betting.

With fond memories of covering The Mirage’s official closing and getting the chance to attend the Global Gaming Expo (G2E) for two consecutive years, Kirk looks forward to continued growth with Global Gaming Insider, and providing outstanding coverage of a dynamic industry for its readers.
