We support individuals who want to improve their health at any stage of life. Through a Functional and Integrative Medicine approach, we focus on identifying root causes and optimizing long-term wellness—not just managing symptoms.
Our Approach to Healthcare
We use a science-based approach that looks at the complex interactions between human biology, genetics, lifestyle, and environmental factors. We then take these factors into account and tailor an approach to your unique needs.
Through targeted testing, a thorough review of your health history, and an assessment of lifestyle and contributing factors, we develop a clear clinical picture of your health. This allows us to identify root causes and focus care upstream, addressing underlying concerns rather than simply managing symptoms.
Taking this patient-centered and patient-driven approach helps ensure a more positive transition to a healthier life.

Meet the Team
Functional Health Professionals
Hi there, I’m Leah, a board-certified acute care nurse practitioner with over two decades of experience in healthcare. I have a master’s degree in nursing from the University of Kentucky and a bachelor’s degree in psychology from Purdue University. My passion lies in functional/integrative medicine, which involves treating the root cause of symptoms, rather than just addressing the symptoms themselves.
Having worked with the chronically mentally ill as a case manager early in my career, I understand the complexities of managing everyday life while dealing with medical issues. As a nurse practitioner, I strive to support not only my patients but also their loved ones in their care. I find nothing more rewarding than helping clients find effective ways to reduce their pain and start to feel human again.
In my practice, I focus on the whole person and the complexity of their issues, taking the time to go through their history and understand what’s causing their symptoms. I have a comprehensive knowledge of all types of disease states and spend much of my free time staying up-to-date with the latest scientific literature to give my clients the best options for their care. I create personalized healthcare plans to treat a variety of conditions and believe that there is no one-size-fits-all approach on the health journey.
I understand what it’s like to suffer from fatigue, brain fog, mold exposure, hormone imbalances, and personal life challenges, which has given me empathy for people challenged by these conditions. I’m passionate about helping others on their personal health journeys and supporting them with a personalized approach that gets to the root cause of what is ailing them. If you’re looking for someone who truly cares and has the knowledge and experience to help you achieve optimal health, then look no further

Giselle Arricivita, BSN, RN
Practice Manager
Giselle is the Practice Manager at Mountain Roots and has been part of the team since 2023. She is a board-certified nurse based in the Philippines, with a Bachelor of Science in Nursing earned in 2010 and licensure completed the following year.
Her clinical background includes hands-on experience in a government hospital across multiple departments, including emergency care, obstetrics and gynecology, medical and surgical wards, and pediatrics. This foundation gives her a strong understanding of patient care, clinical workflows, and the realities patients face within traditional healthcare systems.
After stepping away from clinical practice to focus on family, Giselle returned to healthcare through remote work—an opportunity that allowed her to blend her nursing background, operational experience, and passion for patient-centered care. Since joining Mountain Roots, she has played a key role in supporting daily operations, patient coordination, and behind-the-scenes systems that help the practice run smoothly.
Working closely with patients and providers has deepened Giselle’s appreciation for holistic and functional medicine. Having personally experienced the challenges of seeking answers and feeling dismissed in conventional care, she strongly aligns with Mountain Roots’ commitment to listening deeply, addressing root causes, and treating the whole person.
Giselle is proud to support a practice that prioritizes thoughtful, compassionate care and is honored to be part of each patient’s healing journey.
