Providence Tarzana Medical Center received a $4 million donation from Allison Clago, a member of the hospital’s board of governors, in a signing ceremony on Wednesday at the Providence Tarzana Foundation office.

It marks the biggest donation the Tarzana hospital has received. The hospital is currently raising money for a major renovation and expansion.

Clago chose Providence Tarzana because it was the community hospital where she received care.

“I was treated for breast cancer and my beloved father peacefully passed at Providence Tarzana. Every member of my family has been treated at Tarzana,” Clago said in a statement.

Providence Tarzana is currently raising funds for a $540 million expansion and renovation for the 45-year-old hospital. Renovation has begun at the hospital, including a new patient wing, expanded Emergency Department, second parking structure and expansion of diagnostic and treatment areas.
