As we wrap up Nurses Appreciation Week, we want to honor Annie, our PRN superstar who always steps in to help whenever we need her!

Annie may have moved on to chase her dreams as an RN at a hospital (and she’s thriving—we couldn’t be happier for her!), but she still finds time to come back and support our clinic with the same warmth, compassion, and grace we’ve always known her for.

Annie, you will forever be a GCFM nurse in our hearts. Thank you for continuing to be a part of our story. You make us proud every day!
