Have had a few as my treatment will take at least 12. One really has to rate the whole staff. The scheduling lady is very personable and helpful. The gal who assists the Dr is very nice and highly skilled. Dr McWilliams himself is also very personable. He makes time for any questions I might have. My procedures have been flawless thus far. Nice, modern facility is just the right size. Located on a main street with plenty of parking. Highly recommend.

Although I moved out-of-state several years ago, I have never since found a Family Practitioner who exhibited more kindness, compassion, and expertise as Dr. McWilliams. If I ever return to Illinois, he'll be one of the first stops I make! :)

I have been seeing Dr. McWilliam for 6 months now to treat my varicose veins. His staff is professional and friendly. Dr. McWilliams is professional with a caring bedside manner. Personally concerned with how my legs healed after procedures. 2x's I have had abnormal swelling and he had me come in right away at no charge to address my problems and then had me come in to also make sure I was not having an allergic reaction to the medicine. He truly cared about my safety and response to the treatment and I did not feel like a nameless patient that walked through a revolving door.
