Gabriella Dyke, DO

Hometown: Grand Rapids, MI

Medical school: Michigan State University College of Osteopathic Medicine

What excites you about your residency/fellowship at Corewell Health? I'm excited to come back to West Michigan to continue my medical training and be able to give back to the community that helped me grow into who I am today. I'm looking forward to working with the strong, collaborative team at Corewell Health in West Michigan!

Clinical interests: I have interests in cardiac intensive care and extracorporeal medicine.

Hobbies: I love exploring new parks and trails with my mini labradoodle, Javier. I enjoy being active and love indoor cycling on my Peloton, pilates, and running. I love reading, my favorite genre is psychological thrillers.

Haylee Sprangers, MD

Hometown: Pembine, WI

Medical school: Medical College of Wisconsin-Green Bay

What excites you about your residency/fellowship at Corewell Health? I'm a Midwest girl at heart, but have spent the last three years training in Georgia, so I'm very excited to get back to a state with all four seasons and near family. After meeting the faculty and fellows during my interview, I immediately knew this would be a place where I would feel at home.

Clinical interests: I've done quite a bit of advanced training in breastfeeding/lactation and hope to further explore how breastfeeding can impact outcomes in critically ill infants. My other interests include the human microbiome, ECMO, and gender bias in health care/education.

Hobbies: I spend the majority of my free time outdoors. I love camping, kayaking, paddleboarding, and hiking. You may also find me reading (non-fiction), listening to podcasts, or hanging out with my husband & daughter.
