I’ve had several GI specialists with unfortunate subpar experiences, but nothing compares to Dr .Kaczanowski and his staff which were all exceptional with the utmost professionalism I have ever experienced. Thank you Dr. Kaczanowski and nursing staff.

The worst it could possibly be. Despite having to wait 8 months for a simple follow up, when I arrived I was told I did not have an appointment. Then I was told they had a cancellation for about 30 minutes later if I was willing to wait. I agreed. 10 minutes later I was told the doctor said I had to reschedule. The doctor did not come out an apologize. He obviously is too busy to be polite or professional or caring. The receptionist was polite and apologetic throughout but that was the only good thing about the office. I would not go to this doctor ever again, even if he were the only doctor left on the planet.

Someone else posted that Dr. K made a colonoscopy a fun experience. I agree. His personality, the great nurses and techs at Southern NH, they were the best. Highly recommend.

I can’t say enough about how great Dr Kaczanowski is. Not only does he really listen to what you have to say and your concerns but he truly cares and won’t give up till you are in a good place physically. I highly recommend him to anyone that has any stomach/GI issues.

Very caring and a great sense of humor! He made having a colonoscopy a good experience. Now I tell everyone that they should go have one, and prevent colon cancer. See Dr. Mike!
