Our Physicians

Duncan R. Campbell, M.D.

Dr. Duncan Campbell graduated Magna Cum Laude with a Bachelor of Arts from Vanderbilt University.  Dr. Campbell later completed medical school at the University of Kentucky, where he was one of the top medical students. When asked what led to his decision to choose pediatrics, Dr. Campbell cites his time in the pediatric rotation in medical school as being his favorite, ultimately choosing to complete a pediatric residency at Vanderbilt University Medical Center.

As a Kentucky native, he loves working with children and their families and keeping them healthy. Recalling his personal journey towards becoming a pediatrician he says, “I was 8 years old at church when an adult asked me what I wanted to do when I grew up, and I said I wanted to be a baby doctor.”  Still following that early calling, Dr. Campbell continues to serve as one of Hopkinsville’s leading physicians.

When not at the clinic, he enjoys biking, swimming, jogging, watching college football and basketball, and spending time with his wife and four grown children.


Cristina Cruz, M.D.

Dr. Cruz was born in Manilla, Philippines, as the youngest child of what she refers to as a “very big family.” She grew up loving children and wanting to pursue that passion. She completed a residency in pediatrics at Loma Linda University Children’s Hospital in California following medical school at the University of Santo Tomas in Manilla, Philippines.

Dr. Cruz says she enjoys working with children because they are so resilient and particularly likes working with infants because of their innocence which draws upon her motherly instincts. She appreciates the opportunity to get to know the entire family and watch the children grow up…and begin having children of their own.

Speaking English and Tagalog, Dr. Cruz enjoys serving patients from various cultures. When not at the clinic, Dr. Cruz enjoys reading and general relaxation.
