Internal Medicine Physician

Internal medicine is a discipline that puts me at the front line of disease detection. It’s always an enjoyable challenge to take a patient’s symptoms and create a thoughtful evaluation that leads to a proper diagnosis and treatment.

Board Certified since 1995

Before joining New Pueblo Medicine in 1997, Dr. Zaetta was on the medical staff of Philadelphia Health Associates (Philadephia); Graduate Hospital (Philadephia); North Hills Passavant Hospital (Gibsonia, PA); Allegheny General Hospital (Pittsburgh) and was a medical officer for Indian Health Services in Crown Point, NM. He received his board certification in Internal Medicine in 1995.
