He believes in staying current with new methods and often innovates with new endoscopic procedures.

He also works with critically ill patients. Very problem-focused, he assures that patients leave his office with a specific plan of action.

      Dr. Lowenstein spent time to listen to my concerns, definitely involved me in the discussion about my care, and answered my probably too many questions. He could have brushed me off as an older adult with heartburn, but he ran tests to try to find the cause. I have already recommended him to a friend with similar issues and would recommend him to others without hesitation.

      VERY HAPPY! He isn't a pill pusher and wants to actually find out what's going on and not blowing me off.
