I am honored to be entrusted with the opportunity to care for your family and children. I received my undergraduate degree from the University of Oklahoma and my master’s degree from the University of Texas Medical Branch in Galveston. I am nationally certified as a pediatric nurse practitioner and lactation consultant. I have been in pediatric medicine as a practitioner for over 30 years in various fields of care.

I enjoy working with infants, children, and adolescents. I have many years of experience with newborn care, premature follow up, along with many medical conditions of childhood. Sharing in the growth and development of children throughout childhood has been a focus and enjoyment of my practice in pediatric medicine.
In my spare time I enjoy outdoor activities such as hiking and fly fishing with my husband and two older sons. Gardening and needlework are also passions I enjoy and engage in frequently.

I look forward to partnering with you and your children in their care as we empower them to attain their maximum potential in health and wellbeing.
