RiverPeak Health is excited to announce that Sean McCallister will be joining our team as Interim Chief Executive Officer (CEO) beginning June 1, guiding us through the critical phase of opening our new hospital. With Sean’s passion for small-town communities and experience in rural healthcare leadership, he brings the vision and expertise needed to launch our hospital and shape the culture of RiverPeak Health.

Sean’s leadership in rural healthcare spans more than twenty years, including executive roles in Wyoming, Alaska, and Idaho. Most recently serving as Interim CEO of Powell Valley Healthcare, he has led community-owned hospitals and regional health systems through financial turnaround, facility replacement projects, service expansion, and pandemic response. He is known for building strong teams, strengthening community partnerships, and positioning rural hospitals for long-term success.

Sean’s message to our community:

"I've spent my entire life in mountain west states and thoroughly enjoy rural areas for optimal quality of life and the premier way to raise my family. Small towns are the antithesis of the urban rat race with their charm, close-knit feel, and robust community values. My wife and I are passionate about healthy living and love all things outdoors including snow skiing, water skiing, paddle boarding, bike commuting, mountain biking, hiking, camping, and long Sunday walks together.

“Serving in rural healthcare is an absolute privilege and calling for me. Small hospitals are poised to deliver the best care and service compared to their urban counterparts because we're less complex and bureaucratic and our organizational culture is more intimate. Notably, we literally provide services to our friends, neighbors, and people we see every day at the grocery store, post office, church, etc., which really ups the ante!

“I'm beyond excited about RiverPeak Health! Hospitals are the lifeblood of rural communities because they enhance timely access to quality services and infuse local economies. Reestablishing essential medical services in the greater Riverton area will improve health outcomes and wellness for individuals and families. Ultimately, it will bolster quality of life for all residents. I'm grateful for the opportunity to serve with such a talented and committed team in Riverton and for the support of Billings Clinic. Together we will fully animate RiverPeak Health's mission and revitalize local healthcare.”

RiverPeak Health is thrilled to announce that Dr. Peter McCullough has officially joined our Medical Staff, becoming our very first physician as we prepare to open our doors to the Riverton community.

This is a foundational milestone, and we could not be more excited to welcome a physician whose training, experience, and heart for rural medicine align so powerfully with our mission.

Dr. McCullough is currently completing his Family Medicine/Obstetrics (FM/OB) residency at Via Christi Family Medicine in Wichita, Kansas, with full-spectrum Family Medicine training and advanced obstetrical and surgical OB experience. He earned his Doctor of Medicine degree from the University of Washington School of Medicine through the Wyoming TRUST pathway of the WWAMI program.

He completed his undergraduate studies at Wyoming Catholic College in Lander and later earned a degree in Biology with a Minor in Chemistry from Franciscan University of Steubenville.

Before entering medicine, Dr. McCullough served in engineering leadership roles in the energy sector and worked as an Abuse and Neglect Investigator in Wyoming, reflecting a long-standing commitment to service and accountability.

With deep Wyoming ties, he has completed extensive wilderness leadership training through NOLS, holds a Wilderness EMT certification, and continues to serve by teaching “Stop the Bleed,” volunteering in search and rescue, mentoring future medical students, and supporting underserved families.

Outside of medicine, he enjoys hunting, backpacking, climbing, and mountaineering and is currently working toward his private pilot’s license.

We are proud to welcome Dr. Peter McCullough to RiverPeak Health and look forward to the care he will provide to the Riverton community.

Please join us in welcoming him!

This will be the main entrance of Riverton’s new hospital. Siding, glass, and stonework are all going up, and the exterior is starting to look more and more like the hospital our community has worked so hard for.
