Mission Heritage Medical Group is pleased to welcome Mission Hematology and Oncology to our family. Our new offices will be located on the top floor of the new state-of-the-art Leonard Cancer Institute, adjacent to Mission Hospital. The four-story Leonard Cancer Institute will aim to provide patients direct access to cutting edge treatments and preventative services. Our physicians and staff will provide the highest quality care motivated by compassion for our South Orange County residents. Our familiar culture with these latest enhancements set a path for ongoing improvements in delivering personal care.
