This San Antonio practice offers functional medicine care aimed at identifying the underlying causes of health concerns rather than only treating symptoms. The clinic was founded by Derek Guillory, MD, who has been continuously board certified by the American Board of Emergency Medicine since 2005 and became one of the first certified functional medicine practitioners in Texas in 2015. The team also includes Lucas Tims, ND, FABNO, an integrative oncologist who co-founded the clinic's oncology department.
Therapeutics mentioned include options ranging from stem cells to hormone injections, chosen by Dr. Guillory after personally vetting them. The practice also addresses concerns such as chronic pain, stress and fatigue, weight issues, depression, and skin conditions, and incorporates nutrition, detox planning, and emotional and spiritual support into care.
Root Causes operates as a membership-only practice, with care built around a three-part approach covering targeted therapeutics, nourishment of mind, body, and spirit, and detoxification. New patients begin with a phone consultation followed by an intake screening before starting a membership plan.
