Great physician

Dr. Johnson has been our gastroenterologist for several years and has performed many colonoscopies and endoscopies for us during that time. We have never doubted his diagnoses nor his treatment methods. Also, he is very kind and caring about his patients.

Too Much Ego, Too Little Patient Care

Had seen him a few times, and noticed he had a huge ego/God complex. I was willing to overlook it, since he seemed competent. I went to see him for a specific problem, for which he said he needed to see what was happening. He performed a colonoscopy, and never bothered to follow-up with me, or tell me what the problem was. The problem persisted, and I had to find another doctor. Got right to the bottom of it (no pun intended), and had the issue resolved. When I asked to have Johnson return my calls, I never heard from him.

NOT Recommended

Great folks in his office, unfortunately the doctor runs a "puppy mill" atmosphere with volume, doesn't even know his patients or who they are, has zero followup and runs his abs through the hospital which is not covered by general insurance.

One Star

Dr. Johnson should go take a class on how to talk to patients, when discussing tests he will order. He is abrupt, making it obvious he just wants you to get out of the office and do the tests. He does not discuss the results with the patient, but rather has the front office call you. Any questions you have go back to the doctor and another call made to the patient. He is abrupt and borderline arrogant. He may have an excellent reputation, but his mannerism is lacking caring. I also had my records faxed to another doctor who hopefully will spend time discussing my test results with me personally.
