Branch Basics
Marilee Nelson is the Founder of The House Doctors – Healthy Homes/Healthy Bodies, established in 1992, and the Co-Founder of Branch Basics. She is a Board Certified Nutritionist, Certified Bau-Biologist and Inspector, Healthy Home Building Consultant, and trained in Building Science and food-as-medicine. She also serves on the Advisory Board of Documenting Hope as a materials specialist.
Her personal healing journey—avoiding a kidney transplant, reversing stage 4 endometriosis, asthma, severe allergies, and other chronic conditions, and helping her son recover from complex neurological and immune damage—shaped her life’s mission. Through these experiences, she identified how environmental stressors such as mold, toxic chemicals, EMFs, and indoor air pollution directly undermine health and limit the body’s ability to heal.
For more than 40 years, Marilee has helped children with disabilities and individuals with chemical sensitivities, mold-related illness (CIRS), autoimmune disorders, hormonal imbalances, and neurological challenges reclaim their health by removing immune stressors from their homes. She developed a systematic, category-based method for eliminating harmful products that consistently leads to immediate improvements in indoor air quality and overall well-being.
Through her work with The House Doctors and Branch Basics, Marilee continues to lead a national movement focused on ingredient transparency, environmental health education, and what she calls the “power of removal” — empowering people to create safer homes and restore the body’s natural capacity for healing.
