HSHS Medical Group is pleased to award Zachary Berg, MD, with our August Provider of the Month Award. Dr. Berg is a pulmonary medicine physician for HSHS Medical Group Multispecialty Care - St. Elizabeth’s in O’Fallon, Illinois.

The Provider of the Month is chosen from nominations submitted by fellow HSHS Medical Group team members. “Dr. Berg puts his patients’ care first,” his nominator said. “A patient personally called to thank him for taking care of her the way he did. She stated she had not felt listened to until she saw Dr. Berg.”

“One of the reasons I’ve always liked pulmonology is that many of our therapies lead to drastic improvements in quality of life in short periods of time,” Dr. Berg said. “We often see COPD or asthma patients who have been suffering with poorly controlled symptoms for years. By the time we see them again for a three- or six-month follow up, with just a few changes in treatments, they are already feeling the best they’ve felt in years. It’s very rewarding and my favorite part of this job.”

When Dr. Berg isn’t helping his patients, he enjoys spending as much time as he can with family and friends. He also plays golf, pickleball and chess.
