Provider Bio down arrow

Dr. Michael McManus joined Marshfield Clinic in 2002, bringing an extensive background in pediatric oncology from his previous training, research and practice at Mayo Clinic in Rochester, Minnesota; The Scripps Research Institute in La Jolla, California; and Children’s Hospital in San Diego, California.

“There are very good treatments for children with cancer,” Dr. McManus noted. “It’s very rewarding to collaborate with our medical team to treat patients with complex conditions and restore them to health.”

He enjoys working with children who range in age from infants to young adult. “They have a high regard for good health and are real fighters,” he said.

His practice embraces his patients’ families. “It’s an emotional time, and you draw close to parents,” he observed. “We become a close-knit team, all pursuing the goal of improving their children’s health.”

Dr. McManus earned his medical degree at Georgetown University School of Medicine in Washington, D.C. He served his internship and residency in pediatrics at the University of Massachusetts Medical School-Memorial Medical Center in Worcester. He completed fellowships in pediatric hematology/oncology and in tumor biology at Mayo Clinic-Mayo School of Health Sciences in Rochester, Minnesota.

He is board-certified in pediatrics and in pediatrics-oncology/hematology.

Dr. McManus and his wife, Dr. Mary Hennessy, have two sons. He enjoys baseball, trips to Maine, and following his children through their education and growth.
