Dr. Tessa McCullough has had a lifelong passion for hearing healthcare. Growing up in Boise, Idaho, she spent countless hours in her mother’s audiology clinic—watching firsthand how improving someone’s hearing can transform their ability to connect with the world around them. That early inspiration became her calling.

She earned both her Bachelor of Science in Communication Sciences & Disorders and her Doctor of Audiology (Au.D.) from Idaho State University. She is also certified by the American Board of Audiology. After completing her clinical training, she worked at an ENT clinic in Sioux Falls, South Dakota, before bringing her skills and enthusiasm to the Rapid City Medical Center team.

Tessa provides compassionate, evidence-based care to patients of all ages, helping them stay connected to what matters most—family, friends, and community. She believes better hearing leads to better living.

Tessa was able to live this out in 2024, when she joined a mission trip to Nebaj, Guatemala. There she and a small team screened more than 500 children for hearing loss, fit over 40 hearing aids, and trained local caregivers to support long-term hearing care in their community.

When she’s not in the clinic, you’ll likely find Tessa cooking, snowboarding, hiking and exploring the outdoors with her husband and black lab Koda.
