ABOUT US
Welcome to Idaho County Dermatology, a hometown clinic built on trust, experience, and a genuine commitment to patient care. As the only dermatology clinic within Idaho County, we are proud to provide high-quality, specialized care close to home—care that previously required travel outside the community. Our focus is on building lasting relationships with our patients, listening carefully to their concerns, and delivering thoughtful, individualized care that supports the best possible outcomes.
At Idaho County Dermatology, we believe every patient deserves to feel heard, respected, and confident in their care plan. We take the time to understand each patient’s unique needs and work collaboratively to develop personalized treatment approaches grounded in experience and evidence-based medicine. As a locally rooted clinic, we are deeply invested in the health and well-being of our community and are honored to serve our neighbors, friends, and families. We are proud to be home and grateful for the opportunity to care for our community.
Jeanna is a board-certified Nurse Practitioner with extensive experience in leadership, Dermatological procedures, wound care and medical dermatology. Raised in Grangeville, Idaho, she began her post high school education at the University of Idaho and earned her Practical Nursing degree from Lewis-Clark State College before advancing her career in the Treasure Valley, where she held roles including floor nurse, unit manager, Assistant Director of Nursing, and Director of Nursing. While working in healthcare leadership, she earned her Bachelor of Science in Nursing in 2014 and later served as a nursing care advisor for St. Luke’s Health Partners, supporting patients at high risk for hospitalization and gaining valuable insight into patient-centered care and healthcare access challenges.
Jeanna earned her Master’s degree in Adult Gerontology Primary Care in 2018 and obtained board certification the same year. She began practicing dermatology in 2020 under the mentorship of Dr. Carl Thornfeldt in Fruitland, Idaho, where she received advanced training in medical dermatology and dermatologic procedures. She continued practicing following the transition of the clinic to new ownership and earned board certification in dermatology in 2024 through the Dermatology Nurse Practitioner Certification Board.
