Meet Our Doctors
Four naturopathic physicians. One shared belief that your family deserves better. No subscription needed.
Every doctor at Natural Pediatrix chose this work on purpose. We are not here to rush you through a 10-minute visit and hand you a prescription. We are here to know your child, listen to you as a parent, and build care that actually fits your family.
​
Our team is trained in both conventional and natural medicine. We run labs, we can prescribe when something genuinely calls for it, and we refer out when needed. But our first move is always to understand the whole picture before reaching for a solution.
Dr. Heather Dirkmaat, ND
Managing Physician and Owner
Queen Creek and Scottsdale
Dr. Dirkmaat founded Natural Pediatrix because she kept seeing families turned away from conventional practices for their vaccine choices. She believed every family deserved a real medical home, regardless of where they landed on that conversation. So she built one.
​
Dr. Dirkmaat received her Doctorate of Naturopathic Medicine from Sonoran University of Health Sciences. She holds a Master of Biomedical Sciences from the University of Northern Colorado and a Master of Biotechnology from Johns Hopkins University, where she researched genetically modified organisms. Her undergraduate research at the University of Colorado-Denver earned three academic awards for her work examining atherosclerosis development in pre-menopausal women. She continues to serve as adjunct faculty in the Research Department at Sonoran University of Health Sciences.
​
The research background is not just impressive on paper. It means Dr. Dirkmaat reads the studies, integrates the evidence, and makes recommendations grounded in real science. Her approach blends Western and Eastern medicine to find the best outcome for each individual patient.

Dr. Kandace Mecham, NMD
Dr. Kandace Mecham earned a dual baccalaureate from Indiana University of Pennsylvania, receiving bachelor’s degrees in Dietetics and Journalism and Public Relations. She went on to earn her Doctor of Naturopathic Medicine degree from Sonoran University of Health Sciences in June 2026.
​
Her interest in naturopathic medicine began in childhood with a fascination for botanical medicine and later developed into a passion for nutrition. During her first year working as a nutritionist, she welcomed her first child. Shortly after beginning naturopathic medical school, her son was diagnosed with severe autism. This experience shaped her professional path and deepened her commitment to understanding autism and the medical conditions that can affect the health and daily lives of individuals on the spectrum.
​
Throughout her medical education, Dr. Mecham devoted herself to studying both naturopathic and conventional approaches to autism-associated health concerns. Her interests include gastrointestinal disorders, nutritional deficiencies, metabolic and mitochondrial dysfunction, immune dysregulation, cerebral folate deficiency, and the role of clinically relevant genetic variants in individualized care. She is particularly passionate about recognizing underlying medical concerns that may be difficult for children with communication differences to express.
​
Dr. Mecham completed an autism certification in 2025 and is pursuing advanced training through the Medical Academy of Pediatrics and Special Needs (MAPS) Fellowship Program. Her experience providing habilitation services for a child with autism has further strengthened her appreciation for practical support, developmental progress, independence, and collaboration with multidisciplinary care teams. She brings both professional training and a parent’s perspective to helping families navigate complex medical and developmental needs.
​
Dr. Mecham welcomed two more children during medical school, further strengthening her love for pediatric medicine. As a mother of three, she values listening closely to parents, respecting each child’s individuality, and creating care plans that fit the realities of family life.
​
At Natural Pediatrics, Dr. Mecham is dedicated to looking beyond symptoms to identify and address underlying contributors to illness. Her approach draws on nutrition, botanical medicine, and evidence-informed naturopathic and conventional care. She is committed to partnering with families to support each child’s comfort, health, development, and quality of life.
