Aloha! My name is Liat Miller. I am grateful to call Maui my home and I am committed to the health and safety of our community. I was born and raised in Israel where I served as an Air Force Officer. Shortly after my service, I graduated from Bar-Ilan University with an undergraduate degree in Biotechnology. Continuing my education at the University of Hawai’i at Manoa, I earned my second undergraduate degree in Nursing as well as my Masters in Nursing as a Family Nurse Practitioner. In my spare time, I enjoy surfing, yoga, canoe paddling and hanging out with my two dogs. I am passionate about whole-plant-based diet as I strongly believe in its power to improve and prevent chronic diseases such as obesity, diabetes, heart diseases and more. While working at the Pukalani Family Practice with our great Ohana, I aspire to empower individuals and families to improve their lives with high quality healthcare.
