Lynn Malerba

Malerba's mother holds the position of Tribal Nonner, an elder female of respect, and her great-grandfather was Chief Matagha (Burrill Fielding), a position he held from 1937 until he died in 1952.

Malerba studied nursing at Hartford Hospital College of Nursing, and then earned a Bachelor of Science from St. Joseph's College (now known as the University of Saint Joseph) in West Hartford, Connecticut, in 1983. She later earned a Master of Public Administration from the University of Connecticut and a Doctor of Nursing Practice from Yale University.

Malerba is married to Paul Malerba; they are the parents of two adult daughters, Elizabeth and Angela. They have three grandchildren.

Malerba worked as a nurse at Hartford Hospital and then moved to Lawrence + Memorial Hospital in Connecticut where she would become the head of cardiology and pulmonary services.

Within the Mohegan Tribe she has been the chair of the tribal council, and worked as executive director of the health and human services department. Malerba was named the 18th chief of the Mohegan Tribe on August 15, 2010, and is the first female chief in modern history to hold this position. She serves on the United States Department of Justice Tribal Nations Leadership Council, and joined the Indian Health Service's Tribal Advisory Committee in 2015, a committee she leads as of 2022.

On June 21, 2022, President Joe Biden announced his intent to appoint Malerba to serve as Treasurer of the United States; she was sworn in on September 12, 2022, and is the first Native American to hold this position. Before her swearing-in, the office of treasurer had been vacant for more than two and a half years, the longest vacancy in the history of the United States Treasury. Malerba and Janet Yellen signing currency during Malerba's time as Treasurer of the United States also marked the first time two women signed U.S. currency.
