Mission Viejo, Calif.-based Mission Hospital Foundation received the largest gift in its 23-year history from Judi and Bill Leonard March 21.
The Leonards, who requested to keep the specific amount of the eight-figure gift undisclosed, are longstanding members of the Mission Hospital family.
To honor the donors, the cancer institute, which is currently under construction, will be named the Judi and Bill Leonard Institute for Cancer Prevention, Treatment and Wellness at Mission Hospital.
Over the past 15 years, the Leonards have donated 24 individual gifts to the hospital through their foundation.
"We are humbled and blessed by the engagement of the Leonard family and the enduring impact they will have on the health and well-being of our community," said Tarek Salaway, CEO of Mission Hospital. "Their generosity will enable Mission Hospital to revolutionize cancer care to south Orange County and provide a comprehensive level of care that was previously unavailable in our community."
