Dr. Lesser is a local product, born and raised in Manhattan Beach. He attended
high school at Chadwick before graduating cum laude from Bowdoin College
in Maine. He attended medical School at USC and completed his urology
residency under the guidance of the legendary Dr. Jon Kaswick at Kaiser
Permanente Los Angeles. Dr. Lesser received his advanced robotic surgery
training at Kaiser Permanente West Los Angeles, which boasts the highest
single-robot surgical volume on the West Coast.
Dr. Lesser's focus is on combining proven oncologic principles with
more modern, minimally-invasive surgical techniques. He was trained during
the transition from traditional open surgery to minimally-invasive surgery
(laparoscopy and robotics) for the management of urologic cancers. The
foundations of cancer management began with his early training with Dr.
Donald Skinner at USC, where he learned the open approach to the surgical
management of bladder cancer as well as the various forms of urinary diversion.
Throughout his training, he learned to treat not only bladder cancer,
but also prostate, kidney, and adrenal cancer using these principles translated
to the laparoscopic and robotic arena. While continuing to perform open
surgery - especially for invasive bladder cancer - Dr. Lesser has gained
extensive experience in laparoscopic and robotic prostatectomy, adrenalectomy,
nephrectomy, and partial nephrectomy. More recently, Dr. Lesser has focused
on nephron-sparing surgery (i.e. laparoscopic and robotic partial nephrectomy)
for renal masses, and is adept at all of the cutting edge surgical techniques
required to result in excellent outcomes.
In addition to his extensive and broad surgical experience, Dr. Lesser
has written numerous articles published in peer-reviewed journals as well
as a book chapter. Dr. Lesser serves on the board of the Wellness Community,
a community-based cancer support center in the South Bay.
