A Different Approach

At Lalezari Surgical we aim to treat surgical disease with the least invasive approaches that are currently being used today. These techniques help our patients minimize post-operative pain and help speed recovery.

Innovation and Education

We place great value on the importance of innovation in surgery and continuing education. Dr. Lalezari has authored numerous articles which have helped expand the field of surgery. An area of ongoing interest is enhanced recovery pathways and techniques to help minimize post-operative pain. Dr. Lalezari was an instructor at Johns Hopkins and has had a lifelong dedication to education.




Dr. Lalezari underwent his specialty training in the field of Bariatric and Minimally Invasive General Surgery at one of the world’s leading medical institutions, Johns Hopkins. This translates to excellent outcomes for our patients with a quicker return to work, less pain and faster recovery than afforded by other surgeons who do not employ the latest minimally invasive techniques and fast track/enhanced  recovery protocols. 


An Interview with Dr. Lalezari

As a bariatric and minimally invasive surgeon, Dr. Lalezari, believes the procedures he performs is as much about the lives that are positively affected as it is about the weight loss or surgery itself.

To take someone who has struggled with something for their entire life, who are taking a multitude of medications, and then to see them be able to play with their kids, and go out and live a life that they could’nt before is very rewarding, he said.

Dr. Lalezari completed a bariatric and minimally invasive surgery fellowship (specialty training) at Johns Hopkins Medicine in Baltimore, MD, and is now opening an advanced bariatric and minimally invasive general surgery practice in Los Angeles where he grew up.

At Johns Hopkins, he learned the most cutting-edge procedures such as single-site surgery, robotic and endoscopic surgery truly incisionless surgery, he called it. Training at JHU was an honor and has put him in a unique position when starting private practice.

Born in Iran, Dr. Lalezari moved to California with his family at age 4. With the help of a highly influential primary school teacher, he overcame early difficulty with learning the English language to become a high achiever, eventually graduating magna cum laude – and two years early – from UCLA with a Bachelor of Science in neuroscience.

Always dedicated to education, he spent some time as a high school biology teacher, after which he set off on his journey to become a physician.

For his clinical training, Dr. Lalezari trained throughout the United States, including Florida, New York, California, and at Minnesotas prestigious Mayo Clinic. Although he studied neuroscience as an undergrad, he steered his career toward bariatrics and minimally invasive surgery after seeing the long-term effects that his care could provide, as well as the long-term relationships he could develop with patients similar to that of his primary care doctor growing up who first inspired him to pursue a career in medicine.

With bariatric surgery, I love the relationships you develop with the patients, he said. They’re looking for a way out of their current situation, theyve been fighting their entire lives, and you help them meet their goals. In the end, they’re so happy. The relationships that develop with patients over time is why I got into medicine in the first place.

After graduation, Dr. Lalezari earned a general surgery residency at Jewish Hospital in Cincinnati program and he ascended to the rank of Chief Resident. Following residency, he went on to complete his fellowship at Johns Hopkins.

In surgery, his success is now measured in the magnitude by which his patients lives are changed.
