About Us.

“The legacy I would like to leave is, ‘we made a difference.’”

Dr. Pearse Lyons, philanthropist and founder of Alltech

A native of Dundalk, Ireland, Dr. Pearse Lyons was an innovative scientist who immigrated to the United States in the late 1970s with his young family — his wife, Deirdre, and their daughter, Aoife, and son, Mark — and a dream. His vision — to sustain the planet and all things living on it by applying his yeast fermentation expertise to agricultural challenges — came to life in his home garage.

In 1980, Pearse and Deirdre founded Alltech, building it into the fastest-growing company in the global animal health and nutrition industry through innovative technology and strong branding. Alltech remains one of the only privately held and family-owned businesses among the top animal health companies in the world.

Pearse was widely regarded as an inspirational leader and communicator. He lived with passion and purpose until his death in 2017 due to complications following a heart procedure. Whether through small acts of kindness or far-reaching scientific achievement, Pearse was committed to empowering others, inspiring lifelong learning and making a difference.

With Deirdre and Mark at the helm of Alltech, Pearse’s commitment to serving the greater good inspired the Pearse Lyons ACE Foundation, a 501(c)3 nonprofit foundation that supports the philanthropic endeavors of Alltech and the Lyons family. From disaster relief to educational initiatives and support for underserved communities, Pearse’s spirit of giving is reflected in every corner of the world.
