About The Provider

Caleb Petross, PA, provides compassionate, evidence-based care at Holy Rosary Hospital Primary Care Clinic. A Miles City native, he is deeply committed to serving his community, with a focus on rural healthcare and hands-on procedures. His clinical interests include diagnosing and treating infectious illnesses—what he calls “the small evil bugs that make us sick”—as well as select psychiatric conditions, such as conversion disorder, that highlight the powerful connection among the brain, stress, and overall health.

Caleb’s philosophy of care is simple and grounded: treat disease with science and people with empathy. He strives to ensure each patient feels heard, respected, and supported throughout their care.

Outside the clinic, Caleb enjoys an active lifestyle that includes skateboarding, dog training, hiking, fishing, basketball, and swimming.

    We had to see him twice in a short time for different reasons and he did a great job both times. He answered questions thoughtfully, explaining research behind his approach and was very kind with my kids. He had to guide the nurse in one situation with stitches and did so professionally and thoroughly.

    Caleb did a great job and I felt like he wasn’t being flippant with my child’s health, as some PAs have been in the past. His presence makes me more likely to return.
