Pacific Urology Physicians
Our physicians are known regionally and nationally for unusually high success rates in vasectomies and vasectomy reversals, drawing patients from around the country for the two procedures. Our physicians were the first to use robotic surgery in the East Bay area. Pacific Urology is also known for establishing the Kidney Stone Center, the Continence Center and the Prostate Cancer Center of Excellence. The Prostate Cancer Center of Excellence is the only center in Northern California to offer MRI guided 3D biopsies for early prostate cancer detection.
Formed in 1994, Pacific Urology has origins dating back to the 1960s. Our seven physicians possess nearly a century of collective experience. Drs. Wei Zheng, Jeremy Lieb, Richard Long, Jesse Le, Parminder Sethi and Stephen Taylor are certified by the American Board of Urology, with a range of individual experience. Dr. Nguyen is a board-certified OB-GYN who specializes in urogynecology.
