About WellPathNP

Welcome to WellPathNP, where personalized, science-based care is at the heart of what we do. We're a dedicated practice based in Cumberland Foreside, Maine, led by founder and board-certified family health and functional medicine nurse practitioner Karen "Kiera" Preston, MSN, NP-BC, IFMCP.

At WellPathNP, we specialize in integrative and functional medicine, blending the strengths of traditional and holistic care to help you restore your health potential and feel your best. Our focus is on getting to the underlying drivers of symptoms and disease through a comprehensive, whole-body approach.

With years of experience in Western and functional medicine, Kiera brings a well-rounded, insightful perspective to your care. We go beyond surface-level symptoms to uncover the root causes of what you're experiencing. We identify underlying imbalances or dysfunctions through advanced diagnostic testing and a systems biology approach to create a personalized plan that restores balance and supports long-term healing.

Whether you're dealing with chronic illness, GI issues, metabolic syndrome, or hormone imbalances, we’ll help uncover the root cause and create a path forward. We also offer detoxification programs, genetic testing, and preventive care to support your long-term wellness.

At WellPathNP, you’re not just a patient — you’re a partner in your healing. We’re here to listen, educate, and guide you every step of the way.
