passionate about chestnuts. Our roots grew from our chestnut orchards throughout Michigan. Our growers are our biggest asset and help along every step of the process from growing the trees to harvesting the fruits and creating delicious & unique products.

Our Founders

It all started with a beer. Treeborn owes its inception to the visionary minds of the late Dr. Dennis Fulbright (Michigan State University), Roger Blackwell, and Brian Polowniak. These three friends and accomplished individuals brought a wealth of expertise and diverse perspectives to the table, forming the dynamic foundation upon which Treeborn continues to grow upon. Dr. Dennis Fulbright, with his extensive academic legacy and groundbreaking research in all things chestnuts, continue to shape and influence Treeborn's endeavors. Roger Blackwell, a seasoned grower and business strategist, and Brian Polowniak, a visionary in business and product development, carry forward the torch of Dr. Fulbright's vision. Together, Dr. Fulbright, Roger and Brian are the roots of Treeborn, growing it towards new heights of success through a unique blend of knowledge, experience, passion and most of all - friendship.

Dr. Dennis Fulbright

California-born, Dennis was an adventurer who traded the sunny beaches for the snowy landscapes of Michigan. Dennis was Professor Emeritus at Michigan State University until his passing on November 26, 2019.

Moving to Michigan and joining MSU in 1979 in the midst of a snowstorm, he embarked on a lifelong journey with chestnut trees, chestnut blight, and the propagation and enjoyment of the delicious nuts they bear.

Dennis could see the need to
collaborate, and so he sought expertise from many professionals, researchers
from other universities, and even in different countries. He worked with
growers in Italy, Turkey, Australia, Lebanon, and China. Over the years he
mentored many young scientists, bringing them to MSU to learn from him. From all of this, he earned much respect and awards, but even more importantly, many friends.

Dennis was not your typical one-dimensional scientist; he dabbled in everything from wheat and tomatoes to oak, walnut, and Christmas trees. In his so-called retirement, he co-founded "Treeborn," a venture processing chestnuts for food, and "Chestnut Orchard Solutions," harvesting chestnuts each fall. A man who yearned to be outdoors,

Dennis enjoyed hiking, swimming, fishing, kayaking, tennis, cross-country skiing, and train travel. He especially enjoyed sharing stories with those and delicious chestnut beer.

Though we miss him greatly; his love of his family, friends and colleagues lives on today. Dennis' scientific legacy also lives on, benefiting future
generations of both growers and the trees they’re growing. His children and grandchildren are his true legacy, as they will carry forth his commitment and integrity in many fields. Cheers Dennis!
