Dr. Crista Day is a board-certified Doctor of Osteopathy whose clinical expertise bridges the breadth of modern family medicine with the depth of functional and integrative care. A graduate of Liberty University College of Osteopathic Medicine, Dr. Day has completed extensive training in primary care, internal medicine, cardiology, pediatrics, obstetrics, geriatrics, emergency medicine, and hospital-based care.

In addition to her osteopathic medical degree, Dr. Day holds certification from The Institute for Functional Medicine (AFMCP), equipping her with advanced tools to identify and treat the root causes of complex, chronic conditions. Her clinical approach blends evidence-based medicine with holistic, patient-centered strategies—ranging from comprehensive diagnostic evaluations to personalized therapeutic interventions. She is also trained in osteopathic manipulative treatment (OMT), using precise, hands-on techniques to correct structural imbalances and support the body’s natural function.

Dr. Day’s passion for medicine was shaped by her own personal health journey. After facing a hereditary autoimmune disease and finding limited success with conventional treatments, she turned to natural and alternative methods—and experienced a complete reversal of her illness. This transformative experience deepened her belief in the body’s innate ability to heal and inspired her to dedicate her career to root-cause medicine.

Guided by the core tenets of osteopathic philosophy, Dr. Day’s approach is founded on four key principles:

-The Body is a Unit – Health encompasses the integration of mind, body, and spirit.

-The Body is Capable of Self-Healing – When supported properly, the body’s natural intelligence restores balance and wellness.

-Structure and Function are Interrelated – Physical alignment directly influences physiological performance.

-Rational Treatment is Based on These Principles – Effective care addresses underlying dysfunctions through non-invasive, holistic methods.

Rather than masking symptoms or relying prematurely on pharmaceuticals or surgery, Dr. Day focuses on uncovering and correcting the underlying imbalances—whether nutritional, toxic, emotional, or structural—that impede healing. While she recognizes the essential role of conventional medicine in acute and emergency care, her experience affirms that functional and holistic approaches often offer the most powerful and lasting results for chronic illness and long-term wellness.

Dr. Day’s professional achievements include recognition as Science Student of the Year (2010) at Tri-County Technical College and induction into Alpha Sigma Lambda, honoring her academic excellence and leadership. Beyond clinical practice, she has served as a visiting professor of Nutrition and Exercise Science, teaching courses in sports nutrition and motor learning.

Known for her thoroughness, empathy, and unwavering dedication, Dr. Day partners with each patient to develop individualized, sustainable treatment plans that support optimal health, longevity, and vitality.
