Our History

  • On March 1, 1996, life-long Madison residents Marv "Donut Man" and Barb Miller entered into the bakery business with the purchase of a struggling donut shop located in the shadows of Camp Randall Stadium in Madison, Wisconsin. Their vision of providing old-fashion bakery goods, reminiscent of when they were growing up, for Madison and its surrounding communities was their ultimate aspiration.

  • Through a focus on customer service, its employees and the bakery’s processes, the Millers built a foundation that embodies the core values and spirit of small business: hard work, determination, ethics and being an upstanding business in the community it serves.

  • Greenbush Bakery is committed to providing its patrons with products that are prepared with the utmost quality and of the freshest ingredients. In February of 1998 Marv and Barb fostered a partnership with the Jewish community in order to become a certified kosher dairy kitchen. In accordance to Jewish law, the Greenbush Bakery adheres to strict and high standards in order to maintain “Kashrut” throughout its operations. As a result of this commitment, the phrase “Kosher means quality” is visible in all of the Greenbush Bakery’s marketing and packaging elements, especially from the infamously trademarked "Donut Man".

  • On June 1st, 2017 the Miller's opened a second Greenbush Bakery location on the Eastside of Madison at 5225 High Crossing Blvd. On August 28th, 2019 the Miller's relocated their Downtown location of 23 years from 1305 Regent Street just across the street and a block down and even more so in the shadows of Camp Randall then previously to 1402 Regent Street in The Regent apartments. We continue to operate and make donuts fresh daily at both locations.

  • It is an honor and privilege to proudly serve our customers and community with a quality product and purchase experience. We thank our loyal and future customers in making us a part of your lives and supporting a small family business.

The Donut Man

Marvin “Donut Man” Miller, the original founder of Greenbush Bakery and a Madison legend, passed away on Friday, March 8th, surrounded by his family.

For the last 28 years, he built the bakery into a Madison staple, forming countless relationships and friendships within the community. Many customers may remember Marv’s warm greeting and his playful offer to try a donut, saying, “If you don’t like it, then just throw it on the floor.

Greenbush Bakery was his pride and joy. Although he referred to himself as “the picture on the box” in recent years, he never stopped selling. He was as straightforward as they come and he loved to paint the picture in your head of who we are and what we do.

Marv was very proud of his achievements, and rightfully so. His legacy as a beloved entrepreneur and friend will continue to inspire many. He leaves behind a thriving business and a family determined to carry on his legacy for years to come.

The business is now owned and operated by Marv’s grandson, Taylor Carlson, who had the privilege of being mentored by Marv for many years and where he taught him the right way to do things. Marv’s daughter, Lisa Carlson, a teacher in the Madison area for almost 30 years, helps out at the bakery on weekends, summers, and whenever she can. Jeff Carlson, his son-in-law, assists with the business operations, along with many other family members and friends who are always ready to lend a hand when needed.

Our family is incredibly proud of all that Marv accomplished during his lifetime, and we know he’s now in a better place, making and selling donuts with even more of a heavenly touch. Through every donut served and every smile he shared, The Donut Man’s spirit and vision live on.
