- ColonoscopyI would like to commend the staff at SAGEC North for their exemplary demeanor with their patients. I am a returning patient for the colonoscopy procedure with Dr. Joseph Johnson, this being my 4th procedure, performed early this morning (11-30-16). The entire staff is warm and friendly toward each patient, placing the patient at ease and made to feel welcome. Their personal interaction with the patient is very much appreciated. Dr. Joe Johnson is, in a word, wonderful, and an expert in his field. Thank you very much.
