​Mark D. Greenfield, M.D.

Picture
"When a new patient walks into my office, I want them to feel welcome. I always try to talk with both the parents and the children-to get to know them and to let them know how our office runs. I know that families come from many backgrounds with varying philosophies about how things should be done. I take the time to listen to my patients, the parents' ideas, as well as explain how I com to my decisions and my treatment recommendations."
​
"Sometimes parents ask, 'Was I right to come in?' I want parents to be comfortable calling us when they feel they need to. Parents should rely on their intuition...I never want anyone to feel silly bringing their child in to be checked. If their child's illness is less severe than they thought, that's fine. We'd rather be safe than sorry."
