Jeannette made his American Le Mans Series debut in 2000, scoring six top-10 finishes in seven starts in both the Prototype and GT classes.

Driving for his father's Green Earth Team Gunnar outfit, Jeannette became the first LMPC pole winner in series history.

He shared the honor with season-long co-driver Ricardo Gonzalez and Genoa Racing's Eric Lux, who ended up on equal points to the CORE autosport duo.

In 2005, Jeannette ran his first full season in the Continental Tire Sports Car Challenge, finishing sixth in GS Points Standings with two victories to his credit driving for Multimatic Motorsports.

Jeannette has also participated in world record skydives and has been featured on MTV, People Magazine, USA Today and several other local and national publications.
