What we offer
World-class care for complex chronic illness
At Oak Tree Integrative Medicine & Spa, we specialize in the care of complex, chronic conditions that often go unresolved in conventional settings. Under the guidance of Dr. Katie Dahlgren, our approach is rooted in identifying and addressing underlying drivers such as chronic infections, Lyme disease, mold toxicity, and neuroinflammation. We combine advanced diagnostics with integrative therapies—including neurofeedback, Frequency Specific Microcurrent, acupuncture, clinical skincare, and sauna therapy—to create highly personalized treatment plans. Our goal is to restore balance, improve resilience, and support long-term healing at the root cause level.
Pediatrics
Dr. Katie Dahlgren brings a highly specialized, root-cause approach to pediatric care, with a focus on complex neurodevelopmental and chronic conditions. Drawing on advanced training and over 18 years of clinical experience, she addresses underlying drivers such as chronic infections, immune dysregulation, environmental toxicities, and neuroinflammation in children with conditions including PANS/PANDAS, autism spectrum disorders, and chronic illness. Her integrative model combines targeted medical therapies with supportive modalities to optimize neurologic function, immune resilience, and overall development. Care is highly individualized and designed to support both the child and family through a thoughtful, comprehensive healing process.
Detoxification
At Oak Tree Integrative Medicine & Spa, our detoxification services are designed to safely support the body’s natural pathways of elimination and restore optimal function. Under the guidance of Dr. Katie Dahlgren, we offer advanced IV therapies alongside therapeutic modalities such as castor oil body wraps and full-body lymphatic drainage to enhance circulation, reduce toxic burden, and support immune resilience. Each protocol is thoughtfully tailored to the individual, addressing underlying contributors such as environmental exposures, chronic illness, and inflammation. This comprehensive, integrative approach promotes gentle yet effective detoxification for improved energy, clarity, and overall well-being.
Injection therapy for chronic pain and injuries
Dr. Katie Dahlgren is highly experienced in a range of advanced injection techniques, including neural therapy and perineural injections for the management of acute and chronic pain conditions. Her clinical expertise extends to platelet-rich plasma (PRP) for both regenerative orthopedic care and aesthetic applications, in addition to medically supervised intravenous therapies. All treatments are performed at Oak Tree Integrative Medicine & Spa with an emphasis on precision, safety, and patient-specific treatment planning.
Optimizing hormones
At Oak Tree Integrative Medicine in Woodinville, WA, we utilize a range of integrative medicine approaches to support optimal hormone balance for both men and women at every stage of life. Dr. Katie Dahlgren works closely with each patient to develop a personalized plan, which may include targeted nutrition, lifestyle strategies, supplementation, and when appropriate, HRT with prescription bioidentical hormone therapy. As an EvexiPEL Certified Provider, she also offers advanced hormone pellet therapy as part of a comprehensive, individualized approach to care, complemented by innovative treatments like platelet rich plasma therapy.
