Geisler made his debut at Nashville in spring 2004, starting 23rd and finishing a respectable 24th, six laps off the pace. Geisler would have decent runs in the other eleven races, only crashing out of two of them and earning career best runs of 21st (twice) and 22nd (twice) with a best start of 20th at Pikes Peak. His last start was a 21st at Mephis.
Geisler was supposed to run a similar schedule for the team in 2005, but the team and Geisler split before he made another start. At last check, he is currently the crew chief for Sam Hornish, Jr. in the Sprint Cup Series
