Why O3ASIS?

O3ASIS was founded in 2023 with a vision to redefine how healthcare is delivered. Created to better serve both individual and community health, O3ASIS integrates contemporary research with evidence-based integrative modalities to provide thoughtful, patient-centered care. The clinic was built on the pillars of equity, autonomy, and sustainability—ensuring that patients feel empowered, informed, and supported in their health decisions. By bridging conventional medicine with restorative and longevity-focused strategies, O3ASIS was designed to create a more intentional, accessible, and forward-thinking model of care.

Meet me, Evin Toomey, Family Nurse Practitioner. I’m a wife and mother, athlete, a human biology research fanatic, and a truth seeker. Professionally I have serviced the public as a Registered Nurse, Public Health Nurse, and Family Nurse Practitioner in the state of California. I'm traditionally trained in acute care with clinical experience in ICU, Oncology, and Western Medicine (allopathic) Primary Care. I earned a Master's Degree in the Science of Nursing as a Family Nurse Practitioner with the objective to radically improve human health and the National healthcare system. I am fortunate to have vast experiences in Integrative Medicine working with Functional Practices since the 1990’s. Prior to immersing myself in the healthcare industry I specialized in production management and quality control, ensuring that products were manufactured to spec, on time, with superb quality while eliminating production line bottlenecks. This formative background gives me a skillset and framework not taught in traditional medical education. My practice is built on five pillars: Martha Roger’s Science of Unitary and Irreducible Human Beings, ethical principles, root cause analysis, and holistic healing. I am proud to say that advanced practice nursing is my true calling.

As a healthcare practitioner, my objective is to heal and empower individuals, families, and communities. Amongst the many hours I have spent at the bedside with patients and families in oncology and intensive care units, I have noticed a few common trends; prevention is the best medicine, chronic illnesses can be improved and eliminated, root cause analysis are essential, and shared decision making renders favorable outcomes.

With a personal desire to age well, and the objective to promote my family's health, I've researched and refined simple health routines that ensure health and longevity. Ascribed by my love for people, I've decided to share my passion for research and root cause medicine through coaching, blogging, and quality interventions such as intravenous (IV) and phototherapy. If you're looking to improve your health then I'm your gal!
