About Us

Our History

Our practice was founded by Dr. Leela Prasad, a pioneer in complex colorectal surgery in the Chicago area and, later, in the robotics in the colorectal field.

Laparoscopic (minimally invasive) colorectal surgery became widely accepted in the treatment of colon and rectal cancers in 2004. To ensure that our patients were able to benefit from this treatment, Dr. John Park was invited to join the practice and to use his training in laparoscopy to help create our laparoscopic program. Very quickly, we were able to offer a majority of abdominal procedures laparoscopically.

Dr. Slawomir Marecik became the practice's third partner. He has advanced our minimally invasive program in laparoscopy as well as in robotic surgery.

Dr Kunal Kochar became the practice’s fourth partner. He continues to advance our laparoscopic and minimally invasive transanal surgery program.

It was with great sorrow in December 2016 that we had to announce the passing of the founding father of our practice Dr. Leela Prasad. This wonderful human being and practitioner will be fondly remembered and greatly missed by all of us.

Today our group is proud to serve patients throughout Chicagoland, Northern Illinois, Northern Indiana and Southern Wisconsin. All three physicians are widely respected by colleagues in their field locally, as well as at the national and international levels. In addition, all three physicians proudly hold academic positions at major Chicago universities.

Our Physicians

A team approach to patient care means that patients have access to a surgeon during normal work hours, evenings and weekends. This also means that a specialist is always on call to meet your needs.
