Supporters also had a chance to meet three of the club’s new signings - Angus Macdonald, Tim Swinson and Byron McGuigan.
Gregor gave a presentation on the season ahead, before breaking to introduce himself informally to the fans, who also had the chance to get to know the players.
Gregor told www.glasgowwarriors.org: “I’d like to thank the supporters who gave up their time to come to our new home at Scotstoun last night. It was great to see so many people there, and I really enjoyed the chance to introduce myself and my ideas.
“The passion of the fans is very clear, and there’s also an obvious excitement about the move to Scotstoun and the opportunity to build on the progress the team has made.
“I know our Season Ticket Membership sales are very positive, and it’s fantastic that the supporters share our sense of anticipation about the coming season.”
Gregor also said Glasgow have plans for a home friendly with Exeter Chiefs and a trip south to play Sale Sharks.
