Natalie Crump,
PA-C
Open Fertility Provider
She / Hers
Natalie is a highly skilled and versatile Physician Assistant (PA-C) with close to 10 years of expertise across reproductive medicine, oncofertility, and women’s health. Her passion for fertility was established while serving as a research assistant and patient navigator for the University of Colorado Oncofertility Program before becoming a PA-C. In observing the inequity between patients who were able to afford fertility preservation treatment and those who were not, Natalie created an initiative to offset the cost of those treatments for patients in need. This same dedication and her desire to expand access to fertility care led her to return to the specialty after training.
With a Master of Science in Physician Assistant Studies from Rocky Vista University and a Master of Science in Medical Sciences from the University of South Florida Morsani College of Medicine, she brings a sophisticated clinical skillset paired with a genuine warmth and dedication to every patient she serves. Before joining Open Fertility, Natalie practiced at Kindbody across several California locations, where she developed a deep specialization in reproductive medicine and fertility. Her approach to care is shaped by her belief that every patient deserves to feel truly understood, and she works collaboratively with patients and care teams alike to build treatment plans that are thoughtful, personalized, and grounded in the latest evidence.
Natalie is excited to bring her experience to Open Fertility’s Roseville location, where she looks forward to doing what drives her most — helping people take meaningful steps toward the family they’ve been dreaming of.
