MARQUETTE — One of U.P. Home Health and Hospice’s hardest workers is stepping down.

Jeff Nyquist, who served as CEO for seven years, left the organization Wednesday. Nyquist made the decision in order to devote his full energy to his own company, NeroTrainer. The start–up is an extension of his doctoral and post–doctoral research at Vanderbilt University, where he discovered a technique to enhance visual functioning in blind children.

CEO functions at U.P. Home Health and Hospice have been taken over by the executive management team.
