About Me


Welcome to the Urology Center of Southern California.  Since joining the practice in 2001, I have been fortunate to see our practice grow into an innovative and talented group of urologists. As a board-certified urologist, I enjoy treating patients and providing them options to manage their urologic problems.


After growing up in central New Jersey, I traded cold winters for the warm, sunny days of Southern California to attend UCLA for college.

Before settling down, I went to Minnesota for medical school and residency.  Loving the weather and all the recreational activities that southern California has to offer, I returned with my amazing wife to settle down here with our three children. Outside of work, I cherish my time spent with my family.  We enjoy outdoor activities and playing sports from golfing, tennis, and fishing to basketball.

About My Practice


In my practice I enjoy the day to day interaction with my patients as I listen to their urological issues.   I strongly believe patients deserve being treated with compassion and respect.


I see females, males, adults and children, for urological conditions ranging from the common to the complex.   My focus is to treat patients with the least invasive and most effective treatment options.


I have special interest and training in Female Urology (non-invasive vaginal sling, cystocele, and rectocele procedures), Non-Invasive Prostate Procedures for benign and malignant diseases (laser vaporization, Microwave, TUNA, Cryo-Ablation, and seed implant), Endo-Urology for non-invasive stone and stricture diseases, Laparoscopic Prostate and Kidney Surgery (da Vinci Robotic technique), and Male Infertility (vas reversal).
