She enjoys building longitudinal relationships with patients. For Dr. Mims, it's not only about the medicine, but being a part of her patients' lives. Taking care of whole families, from kids to parents to grandparents; hearing about their lives, vacations, and new grandchildren, brings special purpose to Dr. Mims' practice.





Dr. Mims sees patients of all ages, helping them maintain general wellness and manage chronic conditions. Her clinical interests include women's health, contraception, hypertension, diabetes, hyperlipidemia, wellness and prevention, and children's care. Dr. Mims works to help her patients to understand the "why" behind her care plan for them. Some of what we do in medicine results in situations with multiple right answers with varying degrees of evidence. She engages patients in understanding their options to make the best decision together about what may work best for them.
