About Dr. Kowalczyk

Dr. John Kowalczyk is a urologic surgeon in Los Angeles, California and is affiliated with multiple hospitals in the area, including California Hospital Medical Center. He received his medical degree from Chicago College of Osteopathic Medicine and has been in practice for more than 20 years. He is one of 5 doctors at California Hospital Medical Center who specializes in Urology.

“I chose urology because it presents a unique opportunity to positively impact people’s everyday lives in a positive way. Whether it is giving the freedom to venture away from where a bathroom is nearby or helping improve sexual health, performance, and intimacy, our patients often see real differences as a result of their treatment. It’s gratifying that they place their trust in me to discuss delicate problems and work with them to achieve acceptable solutions.”
