She obtained her diploma in nursing, then went on to earn her Bachelor of Science in Nursing and Masters of Science in Nursing with a Family Nurse Practitioner focus. During her time working with new moms and babies, it became clear that mental health touched her practice, and she felt compelled to focus on the mental health needs of this population.
