Your Health is What Matters to Us

When people experience urologic conditions, it can be embarrassing and often complicates their lives. Such situations can be intensely personal and difficult to talk about. The doctors of the Urology Group of Southern California strive to create a supportive environment where people can feel comfortable discussing their medical issues with their doctor. Over the years, Urology Group of Southern California has helped thousands of patients address their urologic issues and improve the quality of their lives. Our programs include diagnostic imaging, physical therapy, prescriptions and surgical treatments.


Dr. Kowalczyk has not only completed a full training program in urologic surgery, but also has augmented his basic training in additional areas of urologic science. He is involved in all aspects of urologic disease and management.
