Greg Glander has been in the Toyota Corporate Fleet Dept. for 12 years (and with Toyota for 23 years). His first assignment involved the successful launch of the first generation Toyota RAV4EV, which continued with Glander’s involvement in fleet sales with Toyota’s first generation Prius.

He was recognized at Toyota for selling the company’s first 350 “first generation” Prius models to the City of New York. Throughout the years, Glander has represented Toyota at various “green fleet” trade shows, and has assisted with Toyota’s prominence in the area of advanced technology vehicles as it relates to fleet sales.

He is a member of the NAFA Fleet Management Association and in his current assignment, he is responsible for Toyota’s Prius plug-in hybrid and RAV4EV fleet sales strategy, as Toyota looks forward to the successful fleet launch of those two products.


Head has been dedicated to sustainability in the Fleet Management industry for more than 20 years. He has been a leader in promoting hybrid-electric vehicles and developing the infrastructure necessary to grow this rapidly expanding market segment. His efforts were recognized by bestowing the County of Sonoma the “Most EV Ready Community in the Bay Area” award. Below is a summary of all of his accomplishments, awards, innovative work, and dedication to the industry in the area of sustainability over the last 20 years.

Ivy guided construction of a new, sustainably-built fleet maintenance facility and develops policies that support fleet utilization and the purchase of the most fuel-efficient and least-polluting vehicles available. His incorporation of new green technologies promotes ongoing development of sustainable fleet transportations solutions.
