Welcome to Lionheart Integrative Healthcare, where your well-being is at the heart of everything we do.
We believe true healing begins at the root or core of the problem, not just with symptoms. We take the time to get to the bottom of it all and understand your unique needs, then work WITH you to support your mind, body, and spirit through personalized, integrative care.
Our team combines years of experience in lifestyle medicine, nutrition, functional medicine, and holistic care, offering thoughtful, compassionate guidance to help you achieve long-term wellness and vitality.
Whether you are managing a chronic condition or merely seeking to optimize your health, Lionheart Clinic is here to support your journey with care that is as individualized as you are.

Dr. Elizabeth Eversull is passionate about helping her patients heal by uncovering the root causes of illness, restoring balance, and supporting the body’s natural ability to thrive. She combines her expertise in functional and integrative medicine with the understanding that health is deeply personal, and each patient’s journey deserves time, attention, and compassion.
During medical school, Dr. Eversull developed extreme fatigue, fevers, and repeated bouts of pneumonia. Brain fog set in, and she went from the top of her class to struggling to think clearly. When doctors told her she “wasn’t smart enough to become a doctor” and recommended she drop out, she refused to accept that answer.
Instead, she asked the questions others didn’t: Could her prolonged exposure to crop-dusting chemicals, mold, lead from stained glass soldering and paint, industrial chemicals, as well as asbestos be related to these symptoms? Through persistent investigation, she discovered these exposures were impacting her health. By creating a personalized regimen of self-treatments and herbal support, she healed herself and reclaimed her vitality.
This experience shaped her life’s mission: to help patients who feel unheard or dismissed find real answers and real healing.
