The Bus Boys Collection : Created to preserve and protect the heritage of the bus industry



Created to preserve and protect the heritage of the bus industry by collecting and restoring vintage buses, as well as industry-related memorabilia, the “Bus Boys Collection”, a 501(c)3 non-profit, was formed by brothers Dan and Stan Holter in 2009.

The Holter family owns the Richfield Bus Company, Rochester City Lines, and Heartland Tours and Travel, operating local and nationwide charter service, commuter service, and tours. The successful family business was started by George and Marilyn Holter in 1959 when Dan and Stan were just boys. Having grown up in the bus business, the brothers developed a passion for preservation and a commitment to seek out and preserve their industry’s history.

The Collection’s over 100 vintage buses represent what is believed to be the largest collection of operable buses in North America, if not the world. A number of buses from the collection operate in our fleet today and have been used for special events and productions sharing the history with others.

You can help the Busboys collection and make a difference!

The Busboys Collection is facing the COVID pandemic in a world turned upside down. Since 2009 the Holter Family, Richfield Bus Company and Rochester City Lines have provided the Busboys Collection with its necessary financial and logistical support. Because the once-thriving motorcoach industry that provided more than 600 million passenger trips annually has been decimated by COVID-19 with nearly 2 million motorcoach-related employees unemployed, the Busboys Collection needs your help. 

Unlike other modes of transportation, such as airlines, rail, and public transit, the charter and tour bus industry has not received direct economic relief to date, placing them in peril. Obviously, this severely impacts the Busboys Collection’s long-established funding sources. Right now, your donations provide critical support to our general fund to bridge the gap for basic upkeep, capital projects, and equipment restorations.


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 - President


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 - Treasurer

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. - Secretary

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.
