Hawaiʻi Health Systems Corporation (HHSC) has matched four new resident physicians with Hilo Medical Center’s Hawaiʻi Island Family Medicine Residency Program (HIFMR). They will arrive in Hilo to begin training this summer.

The physicians, who were matched by the National Resident Matching Program on March 17, are: Devin Hazama, DO; Kallan Ross, MBChB; Mililani Trask-Batti, MD; and Warren Yamashita, MD.

Each of them will train in a three-year program alongside learners from the University of Hawaiʻi at Hilo’s Daniel K. Inouye College of Pharmacy, the University of Hawaiʻi at Hilo’s School of Nursing, the University of Hawaiʻi at Mānoa’s School of Nursing and Dental Hygiene, and I Ola Lahui, a behavioral health training program specializing in rural communities.

“We welcome the latest class of residents into our ohana,” said Dan Brinkman, East Hawaiʻi regional CEO of Hawaiʻi Health Systems Corporation. “We look forward to providing these highly qualified physicians with an excellent training experience.”


HHSC is working to address the shortage of primary care physicians in Hawaiʻi through training and retention. This is the fourth year of its Primary Care Training Program (PCTP), described as “an emerging model of success” in Family Medicine Residency for Neighbor Island and rural communities throughout Hawaiʻi.

“I’m really excited about the new class of residents,” said Dr. Mary K. Nordling, Hawaiʻi Island Family Medicine Residency program director. “As our residency program continues to grow, our residents and faculty are providing high quality healthcare to more and more people of East Hawaiʻi.”

She continued, “We appreciate everyone’s hard work and support for our residency program that is maturing into a medical home for some of the most complex patients in rural Hawaiʻi.”

This fourth class of residents joins: Will Chapple, MD, Tuy-Ngoc “Unity” Nguyen, MD, Karen Rayos, MD, Gaku Yamaguchi, MD; Vincent Giani, MD; Nataliya Holmes, MD; Ashley Noelani Kong, MD; Tereza Molfino, MD; and Kapaakea Charles Puaa, MD.


HIFMR will graduate its inaugural class of residents this summer: Kaohimanu Dang Akiona, MD, Svetlana Shchedrina, MD and Seren Tokumura, MD.
