At Functional Medicine of Delaware, Kayla partners closely with patients to uncover and address the root causes of illness rather than simply managing symptoms. Her clinical interests include pediatrics, women’s health, stress-related conditions, fatigue, gut health, and preventative care. She believes healthcare should be collaborative and empowering, working alongside each patient to develop individualized plans that support sustainable, long-term wellness. Kayla is especially passionate about helping patients restore balance within the body—recognizing that true health comes from harmony among lifestyle, nutrition, stress management, and physiology.
Known for her attentive and compassionate style, Kayla strives to create a welcoming environment where patients feel heard, supported, and truly understood.

Dr. Randy J. Smith, DPT directs the Neural Recovery Program powered by the Neubie at Functional Medicine of Delaware. After more than 15 years working inside the traditional medical and physical therapy model, Dr. Smith realized something was missing: patients were being pushed through insurance-driven systems that prioritized their profits and limiting care instead of complete recovery.
He watched too many people suffer from chronic pain, limited mobility, nerve dysfunction, and lingering symptoms—even after months of conventional care. The traditional model simply wasn’t designed to address the root cause or to give patients the time, tools, and attention they truly needed.
That realization sparked a major shift.
Dr. Smith stepped out of the constraints of insurance-based care and joined Functional Medicine of Delaware to build a rehabilitation and performance program unlike anything else in the region. Today, he offers cutting-edge nervous-system–based recovery using the Neubie, making him the first and only Neufit-certified practitioner in Delaware.
His approach blends advanced neuroscience, neuromuscular re-education, and movement science to retrain the nervous system at a level traditional therapy often cannot reach. Patients who have plateaued elsewhere frequently experience breakthroughs, faster healing, and a renewed sense of possibility under his guidance.
Dr. Smith’s mission is simple but powerful:
to give patients an option beyond “good enough,” and to help them achieve the level of recovery and performance they actually deserve.
