Ashley Ilustre Lizama is a Board-Certified Family Nurse Practitioner (FNP-C) with over a decade of healthcare experience in both inpatient and outpatient settings. Originally from California, Ashley moved to Kaua‘i in 2008 at the age of 19. As a young single mother, she began her nursing journey by earning her Associate Degree in Nursing from Kaua‘i Community College in 2013, followed by her Bachelor of Science in Nursing from the University of Hawai‘i at Mānoa in 2014. In 2018, Ashley became the first registered nurse hired at Makana North Shore Urgent Care, quickly becoming a trusted and integral part of the clinical team. She was promoted to Executive Director in 2020, where she led the clinic through the challenges of the COVID-19 pandemic and played a key role in launching its dermatology clinic. While serving in an administrative role, Ashley recognized her deep desire to return to clinical practice—where she could make the most meaningful impact, one patient at a time. Ashley pursued her Master of Science in Nursing through Chamberlain University, earning her FNP board certification and Advanced Practice Registered Nurse (APRN) license in 2024. Upon graduation, she completed Makana’s inaugural 8-month Nurse Practitioner Residency Program under the mentorship of Dr. Sabrina Haas and Kaitlyn Szekalski, PA-C. She also completed an Emergency Medicine clinical rotation in Salt Lake City, Utah, at various Emergency Departments with the clinic’s emergency medicine physician partners to sharpen her urgent care and procedural experience. Now, as a Family Nurse Practitioner, Ashley provides thorough, compassionate, evidence-based care with a focus on urgent medical needs for patients of all ages. She is known for her calm presence, clinical precision, well-rounded background, and strong rapport with patients and colleagues alike. In addition to her role as a provider in Urgent Care, Ashley is the founder and owner of Kauai Drip, a wellness clinic established in 2021, specializing in IV hydration, hormone optimization, and metabolic health. She embraces a holistic model of care that blends conventional and preventative medicine with integrative therapies to promote long-term wellness. Outside of work, Ashley enjoys traveling around the world, hiking, spending quality time with her family, and serving the Kaua‘i community she proudly calls home.
