Providing you with the best family care & nutrition counseling

Our Practice

Dr. Greenspon’s private medical practice is devoted to nutritional counseling and family practice.


He specializes in helping patients lose and maintain a healthy weight. The program he uses was instituted by his father during the 1950s and has continued to this date. It is tailored to everyone’s individual schedules and needs.


Dr. Greenspon’s sense of humor combined with his thoughtful and caring personality make his patients feel at ease.  The Lansing office is a modern state-of-the-art medical building.  The airy and light-filled waiting room has vaulted ceilings and generous seating.


Patients are seen on a first come first served basis and appointments are not needed.


Although the office contains the newest technology and equipment, there are still pieces of vintage furniture from Dr. Irwin‘s original office of 1949. Ample parking is located in the rear of the building.

Our new satellite office is located in Northfield, just off interstate 94 and Willow Road. Patients are seen here by appointment only.

Our Story

Greenspon Medical was established in 1949 by Dr. Irwin Greenspon. He attended Chicago Medical School, receiving his MD degree in 1942. Upon graduating, he served as a physician on a navy ship during World War II. Shortly after the war, he began his private practice, originally located at 3344 Ridge Road in Lansing, Illinois. Eventually, he moved to a new office building in downtown Lansing at 3232 Ridge Road. During those years, he practiced general medicine which included obstetrics and surgery. He was often busy making house calls to his sick patients.

Dr. Greenspon began practicing nutritional counseling and weight loss in the late 1950s. As time went on, he developed his own technique for helping people to lose and maintain their weight. Eventually his practice transitioned completely into helping people lose weight due to his highly effective and successful program.

On August 1st, 1988, Dr. Greenspon proudly welcomed his son, Dr. Jim, as he likes to be called, into the practice. Dr. Jim knew from a young age that he wanted to be a physician just like his father and often accompanied him on his house calls. They had a strong father and son bond, making it only natural for the two of them to practice together. They spent eight years working together during which Dr. Jim honed his skills and learned all about the weight program.

In order to accommodate his growing practice, Dr. Jim built a brand new office building in 1993 in its present location on Torrence Avenue. The building was new, but the diet program remained unchanged. In 2016, he opened a satellite office in Northfield, Illinois.
