Jillian L Gregory, DO

Pediatrics | Pediatric Critical Care Medicine

I am honored to return to Maine as a pediatric critical care attending physician. I treat my patients as I would want other doctors to treat my own friends and family. I feel privileged to treat children when they require ICU care and work to align the medical team with patients and their families to achieve agreeable goals. My husband and I love Maine and enjoy the great outdoors immensely. We spend our free time staying active and love hiking with our dog Elroy. We take advantage of Portland’s thriving food scene and are excited to continue to explore other areas of Maine.
