• Margaret R. Dunn
    Founder, President & CEO, Dunn Transportation / Ollie the Trolley

    Margaret R. Dunn is the Founder, President, and CEO of Dunn Transportation and Ollie the Trolley, a leading transportation company based in Scottsdale, Arizona. A trailblazer in the industry, Margaret launched her first trolley operation in Omaha, Nebraska at the age of 21, and has since grown her business into a highly respected and award-winning transit organization.

    Since founding Dunn Transportation in 1986, Margaret has guided the company through decades of successful operations, innovation, and expansion. Under her leadership, the organization has evolved from a single trolley to a diversified fleet, including executive coaches and trackless trolleys. She spearheaded the expansion of the private charter division from one vehicle to nine and secured a long-term public transit service contract with the City of Scottsdale, which ran from 1991 through 2017—and was successfully awarded again in 2021 and continues through the present. During this time, she has managed a fleet of 21 city-owned buses purchased with federal grant funding and operated five concurrent Spring Training Baseball routes throughout the Phoenix Valley, beginning in 2000.

    Her vision and operational acumen have led Dunn Transportation to substantial financial growth, increasing annual revenues from $50,000 to $3.5 million. In addition to operations in Scottsdale, Margaret has overseen services in Omaha, Nebraska and Durango, Colorado.

    Margaret’s achievements have earned her numerous accolades, including:

    • Most Admired Leaders – Phoenix Business Journal

    • Sun Devil Select Entrepreneur Award – Arizona State University

    • Overcoming Adversity Award – Enterprise

    • Women of Excellence Award

    • Top 25 Businesswoman of the Year

    Beyond her business success, Margaret is deeply committed to community engagement serving throughout the years on Scottsdale Planning Commission, Scottsdale Transportation Commision, Scottsdale Tourism Development Commission, Los Arcos Ad-Hoc Committee, Scottsdale Ethics Committee, Scottsdale Chamber Board and Experience Scottsdale Board.

    Margaret holds an Executive MBA from the W.P. Carey School of Business at Arizona State University (2012) and a Bachelor’s degree in Urban Dynamics and Transit-Oriented Development from ASU’s Global Institute of Sustainability (2010).
