A St. Paul philanthropist is honoring her late husband with a 60-million-dollar donation to the Mayo Clinic. On Tuesday, Mayo announced that Helen Houle made the donation which will see their newest patient bed tower at Saint Mary’s named after John Nasseff. Nasseff, who died in 2018 at 93-years old, had been a regular giver to Saint Mary’s after his son had life-saving surgery there.   The Nasseff Tower will be the first building on that campus to be named after a former Mayo patient. Houle said she knows that the Mayo Clinic always sets out to give the best care possible.
