At Beyond the Spectrum Wellness, we specialize in supporting children, teens, and families with behavioral, speech, and microbiome health challenges through individualized, root-cause care.

As a Family Nurse Practitioner with a decade of nursing experience and four years as a nurse practitioner, I combine functional medicine with compassionate, family-centered care. My mission is to uncover the why behind symptoms—helping children thrive in their bodies, minds, and daily lives.

My Story

I’m a Christian, wife, mother, and board-certified Family Nurse Practitioner with 14 years of experience in healthcare. Through my years in conventional medicine, I grew increasingly frustrated with the “one-size-fits-all” approach that often focuses on symptom management rather than identifying and addressing root causes. Too often, one prescription leads to another—without true healing. I saw firsthand how a system focused on isolated symptoms can overlook the interconnectedness of the body, sometimes causing more harm than good.

My patients frequently expressed similar frustrations—seeing multiple specialists, undergoing countless tests, yet still lacking answers. They were often told their only option was lifelong medication. This realization inspired me to pursue advanced training and certification in Functional Medicine.

I’m deeply passionate about helping others find lasting solutions through a holistic, root-cause approach. I have a special focus on children and families, supporting those affected by autism, ADHD, depression, behavioral disorders, gut imbalances, and toxin overload. My mission is to bring hope and healing to those who have been told there are no alternatives.

My approach integrates over 14 years of healthcare experience with evidence-based functional medicine principles, always keeping the child and family at the center of care. Together, we’ll look beyond the symptoms to uncover the “why” behind them—and most importantly, create a clear, personalized path toward true wellness.

Autism Spectrum Support

Comprehensive evaluation and treatment plans for children on the autism spectrum, focusing on gut health, nutrition, and biomedical interventions. Research suggests that the gut-brain axis, which refers to the communication between the gut and the brain, is influenced by the gut microbiota and may play a role in conditions such as anxiety and depression. The gut-brain axis plays a pivotal role in Autism Spectrum Disorder (ASD). Current scientific understanding highlights nutritional deficiencies and toxic environmental factors as key contributors to ASD. Our innovative approach offers powerful tools to mitigate these challenges, providing hope for improvement even in advanced cases. Discover how we can support your journey toward wellness—because every individual deserves a chance to thrive.

Digestive Health

Drawing from years of nursing experience to address gut-brain connection and digestive issues affecting behavior and development. Chronic gut dysbiosis, which refers to an imbalance in the gut microbiota, has been linked to a range of health problems and diseases. Gut dysbiosis is a strong addition of stressor on the allostatic load of disease. It has been linked to several diseases such as inflammatory bowel disease, irritable bowel disease (IBS), Nonalcoholic fatty liver disease (NASH)-AKA Metabolic fatty liver disease (MASH), insulin resistance, autoimmune diseases, mental health disorders, etc.
