Black Hills Medical Group is empowering patients to thrive within the community they call home.
This remarkable team includes Dr. Halie Anderson, Dr. Abigail Finley, and Mallory Wipf, PA-C, who focus on allergy and immunology, and Dr. Erika Toyoda, Dr. Kay Kelts, Dr. Sydney Stanley, and Lanesse Purtell, CNP, who focus on family medicine.
Dr. Anderson and Dr. Finley are among only six board-certified allergists in South Dakota — and the only two in western South Dakota and the surrounding region. These providers, along with Mallory Wipf, PA-C, specialize in diagnosing allergies, asthma, and immunological diseases in both adults and children. They develop comprehensive management plans tailored to you, using evidence-based medicine and the latest advancements in the field.
Dr. Toyoda, Dr. Kelts, Dr. Stanley, and Lanesse Purtell offer a compassionate approach to families and individuals. Their goal is to provide unwavering support throughout all life stages — addressing well-child checks, acute care needs (injuries, illnesses, etc.), women's health, and the emotional and mental well-being of their patients. Dr. Toyoda, Dr. Kelts, and Dr. Stanley are all board-certified in family medicine, ensuring that their patients' needs are always their top priority.
This team of experienced professionals is dedicated to helping patients and the community thrive. They are actively involved with community boards, coaching teams, participating in school PTAs, and more — creating an inviting atmosphere that encourages authentic interactions.
