A passion for children’s health drew Jennifer into neonatal and pediatric nursing more than 20 years ago. Originally from New England, she graduated from St. Joseph’s College of Maine with a Bachelor of Science in Nursing. She worked at a Level III NICU before moving to Florida with her husband in 2001, where she worked as a nurse in the pediatric ICU, neonatal ICU and general pediatrics.

Jennifer later earned her Doctor of Nursing Practice in Pediatric Primary Care at the University of Florida and became a board certified Pediatric Nurse Practitioner and Certified Lactation Counselor in 2018. She was also appointed Clinical Assistant Professor with the College of Nursing at the University of Florida.

Now a mom of two boys and a longtime resident of Volusia County, she continues to provide expert pediatric primary care and lactation support to the children and families in her community..
