About
Bio
I am a Board Certified General Surgeon practicing in Encino and the Greater Los Angeles area. I completed my residency training in General Surgery at Saint Barnabas Medical Center in Livingston, New Jersey where I served as Chief Resident in my final year.
My passion for surgery is reflected in the wide variety of procedures I perform. I have a special interest in laparoscopic surgery and am one of the few surgeons in the Los Angeles area who perform Single Port Laparoscopic Surgery procedures.
I have always believed that the best way to care for patients is to care about them and am dedicated to providing my patients with state of the art minimally invasive techniques, and evidence-based treatment strategies, in a comfortable, caring environment. I have received recognition for my achievements with several awards including the Patients Choice Award and Best in Encino Award.
Most importantly is my commitment to superior patient care and education. Teaching is an important part of my practice, and this is reflected in my contributions throughout the community and my rapidly expanding social media presence. I am always available to my patients. Your time is just as precious as mine, and noone should ever wait an hour in a waiting room to see their physician. Therefore, waiting room time at my office rarely exceeds 10 minutes.
