Ms. Deborha Caputo received her Associates Degree from Rockland Community College in Nursing, her Bachelors Degree from College of Mount St. Vincent and her Masters Degree as a Family Nurse Practitioner from Pace University. While Ms. Caputo sees patients in collaboration with all the physicians at DDAR for a variety of gastroenterology issues, she has a special interest in treating Hepatitis C. Through starting a support group for this patient population over 15 years ago when HCV treatment was still in its infancy, Ms. Caputo has been offered many challenges and rewards. She has also been an attendee of the annual Liver Meeting for the past 13 years, and feels fortunate to work with a group of physicians at DDAR who support her interest in continuing education. A large part of her role involves patient education, as a well-informed patient makes the best choices regarding healthcare.
