Physician Bio

As a Certified Pediatric Nurse Practitioner (CPNP), I see children of all ages, from newborns to young adults. I provide a wide range of excellent health care, whether a child is well and just needs a check up or is ill and requires care. After graduating with a bachelors of science in nursing at the University of San Francisco, I completed my Nurse Practitioner education, earning a masters of science in nursing from California State University, Long Beach. Certified by the National Board of Pediatric Nurse Practitioners and Associates, I have worked as a CPNP since 1986. I thoroughly enjoy caring for children and also serving as a lactation educator and Basic Life Support CPR instructor.

When I’m not working, I enjoy spending time with my husband and two sons as well as camping, skiing and hiking.
