Dr. Demaria has been my doctor for over 20 years. After moving out east, I have still remained a patient of Dr. Demaria's. He is a very caring doctor with a good personality. I rate him 5 Stars!

Can't say enough about Dr. DeMaria. He is a caring, personable, thorough physician . He is cautious but not an alarmist. His staff goes above and beyond in every situation. He is a family doctor as well as gastroenterologist. And I use him for both!!
