Carrie Johnson, MD
Medical School: Case Western Reserve University School of Medicine
Emergency Medicine Residency: Mayo Clinic Emergency Medicine Residency
Pronouns: she/her
Dr. Carrie Johnson is originally from rural southwestern Minnesota, where she thought she grew up in a big town because it had a grocery store and a few stoplights. Raised in an exceptionally active family, Carrie competed in swimming, basketball, tennis, softball, and track, and picked up ice hockey as an adult. With additional interests in rock climbing, water skiing, and cycling, there are few sports or outdoor activities she has not yet tried or will not do.
She attended a small NCAA DIII liberal arts college for undergrad, Gustavus Adolphus College, where she played basketball and softball competitively. The strong mentorship at Gustavus led Carrie to pursue a PhD in chemical biology at the University of Michigan. There, she saw medicine from a new lens and became enthralled by the idea of pursuing a career as a physician. She attended the Cleveland Clinic Lerner College of Medicine program within the Case Western Reserve University School of Medicine, which included a research year at the National Institutes of Health. Residency training in emergency medicine brought her to Mayo Clinic, where she fell in love with the camaraderie and breadth the specialty offers. With the support of mentors during residency, Carrie fulfilled her dream of matching into sports medicine fellowship. She is thrilled to join the Maine-Dartmouth program where the strong culture, dedicated faculty, and hands-on opportunities facilitate great training and she can live in a gorgeous area without the traffic of a large city.

Pronunciation of Dr. Gregory Okenabirhie
Dr. Gregory Okenabirhie, the youngest child in a large family, developed an early appreciation for community, resilience, and service. This foundation shaped his passion for family medicine, where he values building lifelong relationships and partnering with patients of all ages to improve health through personalized, evidence-based care.
During his family medicine residency at Maine-Dartmouth, where he served as Chief Resident, his passion for sports medicine grew while caring for athletes and active individuals in the community. Through community-based athletic and medical event coverage, he found great fulfillment in helping patients safely return to the activities that gave their lives purpose. Sports medicine became a natural extension of his family medicine foundation, combining continuity of care with musculoskeletal medicine, injury prevention, rehabilitation, and performance optimization.
After completing residency, he chose to remain at Maine-Dartmouth for fellowship because of the program’s exceptional mentorship, strong community partnerships, and shared commitment to using sports medicine and movement to improve the lives of patients of all ages and activity levels. He believes movement is medicine, while recognizing that pain, injury, disability, and chronic conditions can limit a person’s ability to move. His goal is to meet patients where they are, using the tools of sports medicine to reduce pain, restore function, support mobility, and improve quality of life.
His professional interests include diagnostic and interventional musculoskeletal ultrasound, point-of-care ultrasound, orthobiologics, regenerative medicine, prolotherapy, TenJet, and cryoneurolysis. Outside of medicine, he enjoys community outreach, cooking, high-intensity interval training, mixed martial arts, soccer, and basketball.
