ABOUT OUR PHYSICIANS

More than 135 physicians round out our active, courtesy and consulting medical staff, although the specialists treating the majority of our patients are in the disciplines of family practice, internal medicine, general surgery, orthopedics, otolaryngology, pediatrics, emergency services, ophthalmology, urology and obstetrics-gynecology.

We are affiliated with Marshfield Clinic, one of the country's largest comprehensive medical systems, and OakLeaf Medical Network, a physician-directed health services network providing care in small, personalized settings throughout northwestern Wisconsin. Physicians from both organizations regularly admit, treat and consult at St. Joseph's Hospital. We hold contracts with physicians from other organizations as well, including those who provide our pathology services, emergency services and consultative psychiatric services.

We pride ourselves on delivering personalized, quality health care in a close-knit community. Our physicians also appreciate the size of our facility, which allows for more intimacy and time spent with patients.
