Current Fellows

Dr. BoulosThird Year Fellow

Laura Boulos, D.O.

Laura is originally from the town of Holmdel, NJ. She graduated from Baruch College in New York City as Salutatorian of her class with a major in Finance, prior to then receiving her medical degree from Rowan School of Osteopathic Medicine in Stratford, NJ. She completed her pediatric residency training at Jersey Shore University Medical Center and in her third year became Chief Resident. During residency she worked closely with her mentors in pediatric cardiology, and her research project focused on Kawasaki Disease. Laura has always loved working with children, but during her time as both a student and resident her specific interest in cardiology grew. Laura's interest in pediatric cardiology continues to thrive during her fellowship training, as she has the privilege of working with children with complex congenital heart disease. She is enthusiastic about all of the educational training she will be receiving in Rochester.

Laura came to Rochester with her husband and daughter, whom she enjoys spending all of her time outside of the hospital with. She looks forward to exploring all that Rochester has to offer with her family. Her personal interests include traveling, trying new restaurants/cuisines, creative crafts, and spending time with family.
