Pollyanna Lee, RN
Chief Operating Officer, Herald Christian Health Center

Pollyanna Lee earned her nursing degree from Hong Kong Government School of Nursing in 1983 and began her career as an operating room circulating and scrub nurse. She came to the United States in 1986, and received her Psychiatric Nurse Training and RN License from Loretta Heights College in Denver, Colorado. After working in nursing for twelve years, in 1998, she became the Director of Nursing and Administration in an ambulatory surgery center in Whitter, CA. She spent the next twenty years managing large-scale surgery centers and treated all who worked with her as extended family.

In 2017, Pollyanna made the difficult decision to leave surgery center life to enter the world of Federally Funded Health Care. Joining Herald Christian Health Center was a huge leap of faith for her but allowed her to professionally effectuate her vision to provide high quality, affordable healthcare to the low-income and underserved. She began her career there as the Operations Director, and currently serves as their Chief Operating Officer.

Pollyanna has two grown children and two adorable twin grandsons. She has been married for 37 years to a loving minister, and spends her free time encouraging others at church, travelling with friends, watching movies, and babysitting her grandchildren.
