The Mahaska Health Specialty Group at Mahaska Health Partnership is made up of a talented group of providers that offer care in the following areas: Family Practice, General Surgery, Pediatric Pulmonology/Allergy, Pediatrics, Occupational Health and Orthopaedics.
What is unique about this group of providers is that they are part of the same family of health care providers
focused on the needs of you and your family. If the need arises for a consult, the patient simply walks across
the hall rather than traveling long distances out of town.
The goal of the Mahaska Health Specialty Group is to collaborate when appropriate so patients will have piece
of mind knowing all of their healthcare needs can be met in one place by providers who share the same values
regarding standard of care.
