​​​“I enjoy seeing the ‘complete picture’ of pregnancy, to achieve the best outcomes for mother and infant.”

Provider Bio down arrow

Dr. Kazumasa Hashimoto specializes in maternal-fetal medicine, focusing on the medical and surgical management of high-risk pregnancies. His practice includes monitoring and treatment procedures such as comprehensive ultrasound, sampling of the fluid that surrounds the fetus and fetal treatment.

After engaging in broad-based basic science research in his native Japan, Dr. Hashimoto realized he was more interested in bringing the benefits of research directly to clinical patients. “Connecting the knowledge we gain from research to actual practice helps us in our goal of making even the most difficult deliveries as comfortable as possible,” he said. “This area of practice affects not only the health of newborn infants, but the health of their mothers as well.”

His approach to treating his patients reflects his desire to nurture positive outcomes. “For mothers dealing with complicated conditions, it is important for me to listen and establish trust by being open and providing the information they need.”

He joined Marshfield Clinic Health System after being impressed in general by its medical care and facilities, and in particular by its position as a leading destination for patients who require care for serious obstetric conditions.

Dr. Hashimoto earned a Ph.D. and his medical degree at Osaka University, Japan. He completed his residency in obstetrics and gynecology at Lincoln Medical and Mental Health Center, the Bronx, New York, and a fellowship in fetal-maternal medicine at the University of Maryland, Baltimore.
