John H. Yim, M.D.
Dr. Yim is a brilliant surgeon.
- Patient
John Hosei Yim, M.D., joined City of Hope in 2008 after eight years at the University of Pittsburgh Medical Center, where he developed a breast and endocrine surgery practice and maintained an active laboratory research program. His practice at City of Hope is focused on breast and endocrine diseases, as he continues his research studies through Beckman Research Institute of City of Hope.
Dr. Yim is developing new methods of molecular diagnosis for breast and thyroid nodules to see what treatments, including watchful waiting, are appropriate. He is pioneering the effort to treat cancer patients with baicalein, a natural product derived from a Chinese herb. Formulations of the baicalein are synthesized at City of Hope and clinical trial plans are underway.
A graduate of Yale University and Stanford University School of Medicine, Dr. Yim is praised by his patients for the time he spends educating each patient about their treatment options, as well as his superior surgical skills. He's been named one of the “Best Doctors in America” by Best Doctors Inc., a “Top Doctor” in Pasadena magazine and a “Southern California Super Doctor” in Los Angeles magazine.
