Med­i­cine requires a strong rela­tion­ship between provider and patient. I strive to use evi­dence based med­i­cine in con­junc­tion with lifestyle mod­i­fi­ca­tion to achieve the most favor­able outcomes.

Feb­ru­ary is Amer­i­can Heart Month. In hon­or of this month, Duly Health and Care is offer­ing Coro­nary Cal­ci­um Score CT scans for $75. Heart scans are used to look for cal­ci­um deposits in the coro­nary arter­ies that can nar­row your arter­ies and increase your heart attack risk. Vis­it this page to learn more about these scans or call 630−545−7880 for more infor­ma­tion.

"My first visit with Dr. Fiedler, although I've been going to that office for 30+ years (previous doctor retired). He was very prepared, having carefully looked over my files. He was very thorough and explained all the procedures he was doing as he did them."

"John was focused on the task of doing a pre surgery physical. I asked him questions about existing pain issues outside of the surgery which were mostly set aside by John and not addressed at all. I didn't push for answers but I would prefer having the dr. Be blunt with me and telling me what I was asking about would have to be addressed at another time in another way rather than ignoring it."
