Travis Geisler

Geisler began working as a crew member in NASCAR when he was driving the DCT No. 36, as he was also an engineer for the underdog team. In November 2006, Geisler joined Penske Racing as the engineer for Ryan Newman's No. 12 Dodge. He had spent the rest of that year, his first as a full-time crew member, at Robert Yates Racing, where he had been an engineer on Busch and Cup Series cars for the team. Geisler became a crew chief for the first time in August 2008, when Penske decided to replace Sam Hornish Jr.'s crew chief, Chris Carrier, after the No. 77 team had dismal performances throughout the season and was not as competitive as Penske's other two Cup Series cars. However, even after Geisler's promotion into the crew chief role, things did not get any better and Hornish would finish 35th in the standings, fall out of the top-35 in owner points and fail to qualify for two races (Talladega and Homestead-Miami), and lose the rookie of the year award to Regan Smith. Geisler returned as the crew chief of the No. 77 in 2009, and the team would see an uptick in performance. Hornish earned seven top-ten finishes that year, two of which were top-fives, which resulted in him finishing the year 28th in the standings. In addition, he won the Sprint Showdown. For 2010, the last year of the pairing, Hornish only recorded one top-ten finish (at New Hampshire in September), but still only finished one spot lower in the standings, 29th. In 2011, the No. 77 team would close down due to sponsor Mobil 1 moving to Stewart-Haas Racing, and Penske cut back from three full-time Cup teams to two. Hornish would be demoted to Penske's Nationwide Series program, where he drove the No. 12 car, replacing Justin Allgaier, who left for Turner Motorsports. However, Geisler would instead be promoted to competition director at Penske, a position he has remained in ever since. In 2020, Geisler would return to the pit box for the first time in ten years, as he served as the interim crew chief for Penske's No. 12 Ford of Ryan Blaney in the Southern 500 after Todd Gordon was suspended for the race due to the car's improperly installed ballast.
