Origin Medicine operates as a functional and integrative medicine practice in Tacoma, Washington, where Michelle Sandwisch, ARNP, FNP-C, applies her training from the Institute of Functional Medicine and Institute of Integrative Nutrition to address complex chronic conditions. The clinic specializes in metabolic health optimization, autoimmune disorder management, thyroid dysfunction, and brain health support through peptide therapies and comprehensive diagnostic evaluation. Sandwisch holds certification through the American Association of Nurse Practitioners and structures patient care around identifying root causes rather than symptom suppression, with particular emphasis on hormonal balance and metabolic function restoration.
Origin Medicine offers an extensive peptide therapy program with 27 different peptides available, including metabolic peptides including AOD-9604, Liraglutide, growth hormone secretagogues like CJC-1295, and other specialized compounds. Treatment selection is individualized based on comprehensive health assessments and patient goals.
Sandwisch conducts in-person consultations at the Tacoma clinic, beginning with comprehensive health history review, symptom analysis, and functional medicine testing that may include hormone panels, metabolic markers, thyroid function assessment, and autoimmune antibody screening. Her approach integrates nutritional biochemistry principles from her Institute of Integrative Nutrition training with functional medicine protocols to address conditions including Hashimoto's thyroiditis, metabolic syndrome, chronic fatigue, hormonal imbalances affecting both men and women, and cognitive decline. Treatment plans combine peptide therapy with nutritional interventions, lifestyle modifications, and targeted supplementation based on identified deficiencies and metabolic dysfunction patterns.
Patients at Origin Medicine typically begin with an extended initial visit that includes detailed intake, physical examination, and laboratory ordering, followed by a results review appointment where Sandwisch explains findings and presents treatment options. Peptide therapy administration is taught during office visits, with most patients self-administering subcutaneous injections at home following training. Follow-up schedules vary based on condition complexity and treatment protocol, with most patients returning every 4-12 weeks for progress monitoring, symptom reassessment, and protocol adjustments. The clinic's patient feedback reflects appreciation for thorough explanation of test results, detailed symptom investigation, and the time allocated to understanding individual health concerns.
Origin Medicine serves patients throughout the Tacoma and Pierce County area who seek alternatives to conventional symptom management approaches for chronic conditions. The practice does not offer telehealth services, requiring all consultations to occur in person at the Washington location. Sandwisch's functional medicine methodology emphasizes patient education about underlying mechanisms driving their symptoms, with treatment plans designed to restore normal physiological function rather than indefinitely managing disease. The clinic's peptide selection spans regenerative, metabolic, cognitive, and immune-modulating categories, allowing for customized multi-peptide protocols addressing the interconnected systems typically involved in chronic illness presentation.
