To whom it may concern: I received DHS's letter concerning "Incomplete recommendations" for the Flex Sig. I am truly saddened that I will not be able to continue as a patient of DHS as Dr Mark Hassig is a great physician, and did a great job with my Colonoscopy. As were all the medical staff that I had the pleasure of being under the care of.

Dr. Hassig could have easily sent us on our way after he determined we needed a different specialty but instead went above and beyond any reasonable expectation. Took his time and even set up the needed appt with a different doctor while we were there AND ordered some preliminary standard testing the next doctor would need so we were able to do them that day, saving us weeks of time. Couldn't be happier...only wish I could have him for a primary care dr.
