Our Story

Summit Automotive Partners is a privately-held automotive management group headquartered in Denver, Colorado. We are owned by Mr. George Gillett and family with partners. The Gillett family owns or is partners with some of the most respected brands in the world today. Summit Automotive Partners was founded based on a set of firm beliefs: long-term relationships, the empowerment of employees and customers and the innovation and creativity that come from a positive work environment. It’s not business as usual – it’s business as it should be.

Our Dealership Network

All of our dealerships are built on small town values but have the advantage of a big town network to support them. This network enables each to offer superior selection and volume, distinctive leadership and a consistency of experience that our customers have come to expect from their neighborhood dealership. Summit Automotive Partners is building its dealership network through the acquisition of dealerships and dealership groups with excellent track records in sales, service and customer satisfaction. Our dealership network currently includes: Action Nissan in Nashville, Tennessee; Berlin City Auto Group with locations in Maine, New Hampshire and Vermont; Groove Auto in the Denver Metro area; and Groove Silverthorne in Silverthorne, Colorado. Together, they represent 19 great manufacturer brands. It’s the combined enthusiasm and confidence of our manufacturers and our current and prospective dealership partners that supports our continued growth.
