Ijeoma Linda Bethel, MSN, FNP-C

Linda, as she is known by most, is certified by the American Academy of Nurse Practitioners as a Family Nurse Practitioner and is an active member of Sigma Theta Tau International Nursing Honor Society. Originally from Nevada, Linda earned her Bachelor of Science in Nursing at University of Nebraska Medical Center and her Masters of Science in Nursing at Graceland University in Independence, Missouri. Linda also earned a degree in Bachelor of Science with emphasis on Biology and Health Ecology at the University of Nevada Reno, in Reno, Nevada. Although Linda’s prior experience is predominantly in the acute and intensive care settings, she fell in love with wellness and holistic medicine during her studies as family nurse practitioner.

Linda’s goal is to help patients and their families manage chronic diseases through wellness and holistic approach to care which in turn decrease crisis and the need for hospitalization. She has witnessed the devastating end results of poor management of manageable chronic illnesses such as hypertension, diabetes, and chronic pain to name but a few. Although her personal philosophy is forever evolving, the foundation of her goal is to treat all patients as if they are beloved family members. Linda enjoys cutting edge medical practice and caring for her patients as a whole person, not an illness or a disease. She strongly believes that one’s state of health is a continuum, therefore it makes sense that positivity influences one’s outcome even in the most vulnerable conditions. In her spare time, she enjoys spending time with her 2 children and husband. She also enjoys traveling, beach resorts and photography.
