What Patients Are Saying

"Dr Tim Pflederer.....He is beyond very smart and up to date on cutting edge medical treatment, but he has a compassion and empathy not often found in specialists especially. He always takes the time to listen and do what is needed. I have been a patient of this group for over thirty years and he is above all the best doctor I have ever seen. If you have the good fortune to get Dr. Tim, your are fortunate indeed as all that can be done will be done, he is that good, without question."

"Dr. Jacob is more than a doctor she is a person that has compassion and care for others. My brother was critically ill and in the ICU at OSF. She explained to my family in the utmost compassion about his outcome. The news was not good but I will be eternally grateful that she was able to get my dad to calm down and understand. Please keep doing what you do and I hope that others will follow the example that you are".
