"Most disrespectful experience with a doctor. My dad had an appointment with Milton Johnson and both the nurse and doctor had an attitude... Unprofessional to the fullest extent."

— Medical News Today (Dr. Milton Johnson review)

"Dr. Magiera is a good dr. He listen to what you tell him and gave advice, other GI dr. Just don't care and didn'give any advice at all."
