I have followed Dr. Clark when he was still in Chicago all the way here to Wilmette. Dr. Clark is amazing. His caring bed side manner and research to make sure he is treating you appropriately is what has made me continue to see him when needed. I have been a patient at least 25 years. He has also helped my family members. If there was a Gold Star 10 rating for Dr. Clark he would have received it. He doesn’t just treat your symptoms, he treats the person.
