About Benjamin I. Leach

Benjamin Leach, M.D., takes a passionate approach to cancer treatment incorporating leading-edge therapies from precision medicine to immunotherapy, with a relentless commitment to serving his patients and improving their quality of life. “It’s a privilege to be welcomed into patients’ lives,” he says. Dr. Leach received his medical degree at Tulane University in New Orleans, completed his internship and residency at Los Angeles County + USC Medical Center and continued his training with a hematology/oncology fellowship at New York-Presbyterian Hospital/Weill Cornell Medical College. At Weill Cornell, he pursued his interest in targeted treatment, studying the WNT signaling pathway implicated in colorectal cancer development, for which he was awarded the Weill Department of Medicine Fellows Award in Research. Dr. Leach is excited to be returning to Southern California; he’ll treat patients at City of Hope’s Mission Hills, California, facility.
