What a very nice doctor, He was very caring and listened to my concerns. I haven't had a doctor this sincere and nice in such a long time. I now know why I kept hearing good things about him at the hospital. I would highly recommend!

Dr more interested in typing notes on computer than looking and listening to patient. Office takes average of at least 3 days responding to emails on patient portal.

Waiting over an hour in the treatment room is not my idea of good service, somehow it seems to show that 'my time' has no value. A visit by a nurse with an explanation of why the delay might have helped.

Each of my three in office visits to date with Dr. Janecki have been positive experiences. He has a warm beside manner and good sense of humor, which is helpful and reassuring when one is dealing with worrisome health issues. I'm thankful to have found this physician!

I think the office staff is very friendly and professional. The doctor is very attentive and seems knowledgeable. He imminently dove into the steps to try to come up with a solution. He explained what he was doing, and why hewas doing so. I'd highly recommend his practice! The only reason we had a wait time was because of being a new patient. The other patients in the waiting room where being seen five minutes after their arrival. However, the time I had to wait was virtually nothing!

I was disappointed that I had to wait for 1 1/2 hours to see the Doc. and he only spent 5 or 10 minutes with me. In my opinion, if a doctor is performing surgery, he should not make appointments withpatients on his surgery day. He gave me his opinion but never said how he could fix my problem or what I can expect in the future. He could not answer my question in regards to my problem. But I was impressed with his tract record with regards to colonoscopies. I would probably trust him to do my colonoscopy as long as he promises me he would be the one doing the procedure and not someone else he may be training . It appears some doctors may do this.

I went to Dr. Janecki as a second opinion and after doing some research on providers and hospitals and it was quite a drive for me. He took the time to listen to my symptoms and didn't rush to a conclusionand quick and easy treatment recommendation. He wanted to rule out other possibilities before going straight to surgery that may or may not help like my previous doctor had done, which I appreciate even though more testing is not my idea of fun. It is worth the drive to have a doctor who knows what he is doing and can articulate a plan of action to the patient and keep the patient well informed.
