Board of Directors & Staff

The Busboys Collection is operated and supported by a strong, skilled staff and board of directors. With decades of experience in nonprofit management, historic preservation and the bus industry, they guide the organization’s long-standing mission to inform, connect, promote and preserve.

Dan Holter


As one of the original Busboys, Dan was swept into the bus industry when he was three years old, literally sweeping buses owned and operated by his parents, George and Marilyn Holter, the founder of Richfield Bus Company in Bloomington, MN. As Dan grew, so did his knowledge of and passion for the bus industry. Today, Dan is the president of the Busboys Collection, administering board meetings and working with the rest of the board and executive director to ensure that the organization’s mission is carried out, “to provide the public with a hands on experience to enjoy the history of transportation, keeping history alive for generations to come.” Dan’s all-time favorite bus is a 1949 REO Flying Cloud.

Stan Holter

Vice President

Stan, like his brother Dan, is one of the original Busboys. He is the General Manager of Richfield Bus Company, which was started by his parents over 60 years ago. Originally a city transit service, Richfield Bus Company now provides nationwide charters and tours. For many years, he served as Superintendent of the Classic Bus Division of the Minnesota Transportation Museum. Stan is passionate about the preservation of the bus industry’s heritage. His inspiration to save the “old ghosts of the highway”, was a driving factor in the creation of the Busboys Collection. His vision for the organization is safeguarding the achievements of the past and accurately imparting that history to future generations.

Clavonne Holter


Joining hands in marriage to Dan Holter in 1983, Clavonne’s life has been an adventure revolving around transportation and travel. She has accompanied Dan on countless excursions by bus, car or plane to places near and far for business or pleasure to view, purchase, sell or rescue buses. Along for the ride whenever possible were their five children.

For thirty years she has been an educator at home as well as an active musician in the Rochester area, performing in bands, pit orchestras and at her church. “I will sing to the Lord for He has been good to me.” Clavonne is proud of her Holter heritage and excited to share the Collection with the public.

Christian Holter, M.B.A.


Christian has grown up around buses. Some of his earliest and best family memories involve touring the United States, including all of the lower 48, in a converted 1964 GMC 4106 motorhome. Now serving as the Director of Operations for Rochester City Lines in Rochester, MN, Christian brings an active, current understanding of the private passenger transportation industry to the Busboys Collection. He seeks to benefit and connect future generations with the living history found within the Busboys Collection fleet. Christian also has a passion for evolving transportation technologies and personally enjoys multimodal travel experiences, the more modes the better.

Ross Gabrick

Executive Director

Ross has spent his professional career in the transportation industry and is currently Operations Manager of Richfield Bus Company. The management of planes, trains, trucks and buses has provided him the opportunity to be involved with both current operations and historic preservation efforts across the spectrum of transportation. He is keenly aware of the important role that vibrant non-profits play in the preservation of history and has been intimately involved at the executive level with several successful and sustainable non-profits. His love of all things bus related was fostered by his Grandfather, a forty-five year driver for Minneapolis/St. Paul’s Metro Transit system and his Great Uncle who drove for Pacific Greyhound Lines for many years.
