Dr. Mohammed Ansari is board certified in Internal medicine and completed his residency from University of Missouri, Kansas city. He has also completed training in functional medicine from the institute of Functional Medicine (IFM), and has been trained in chronic infections from ILADS and is a Lyme literate MD. He is also very well versed in mold illness, heavy metal toxicity, environmental illnesses, hormonal imbalances just to name a few. He also considers Dr. Neil Nathan, who is one of the leading experts in environmental illnesses and mold toxicity as his mentor as he has learned from him and is also part of his mentorship program where they have group discussions on difficult cases.

Dr. Ansari’s interest in Integrative and functional medicine came from various different avenues. When he was working as assistant professor of medicine at the University of Kansas, teaching medical students and residents, he used to see the same patients in the hospital not improving on standard of care treatments and wondered about other aspects that were neglected. He then enrolled in the “Institute of functional medicine” which aligned with his philosophy of “treating the root cause of disease and not just treating the symptoms” and “using food, nutrition, lifestyle and supplements in addition to traditional medicine” to enhance the patient’s immune system and eliminate illness. One of the other inspirations to learn about environmental illness and mold toxicity also came to him when his whole family including himself were affected by mold illness from living in a moldy home. 

He is naturally a very curious individual who is always eager to learn and in his free time goes through a lot of published research to get his answers as this is his passion. Although many times intuition is needed in treating patients, he believes there is a lot of research and evidence already out there which physicians and patients can benefit from and he regularly goes over interesting articles with his colleagues to see how to improve patient outcomes.

Dr. Ansari has extensive work experience, he has worked in acute patient care for Inpatient medicine and served as an Assistant professor in Internal Medicine at the University of Kansas Medical Center from 2016 to 2021 where he taught medical students and residents. He has also worked in an outpatient setting seeing patients for various illnesses including primary care from 2021 to 2024 before deciding to open his own practice.  

Dr. Ansari has a special interest and training in treating allergies, reducing the effects of toxic chemicals, exercise physiology, nutrition, weight management, mold illness, heavy metal toxicity and Environmental medicine.

Dr. Ansari spends time with his family in his off time and enjoys reading English mysteries, science-fiction novels, reading research papers, flying radio-controlled aircraft, weight lifting and training martial arts (Jiu-Jitsu/Wrestling/Kickboxing).
