Meet Our Wound & Hyperbaric Team



Mandy Vervaecke, ARNP


  • Education: BSN from Allen College in 1995, Master's in Nursing in 2003 from Allen College
  • Certifications: Certified family nurse practitioner, Certified Wound Ostomy specialist
  • Why wound care? Wound care is fun and exciting because it's different every day. It is very satisfying to have someone arrive with a large, messy, painful wound and make it better with the care we provide. Helping someone heal can be like doing a puzzle or a math problem. There are steps to take and plans to be made. So when someone heals, it is a great celebration that the entire team enjoys!
  • Personal Interests: I love to be with my family the most, but also I love to run every day, play with my two Samoyed dogs and two fluffy cats. I like to get dirty in the garden unless I see spiders. Anything outside is my favorite.
