About Me

A South Dakota native, Marnie Terveen, MD, practicing at Avera Medical Group Obstetrics & Gynecology Sioux Falls, SD, always knew she wanted to help others. She loved science, problem solving and being on teams. Becoming a doctor was a natural fit for her—plus she was inspired by her sister, who’s also an OB/GYN. Her women’s health services include pregnancy care, labor and delivery, wellness and preventive screenings, and surgery.

Expert, Compassionate Care for Women’s Health

From OB care, gynecological needs, including annual exams, to menopause support, Dr. Terveen provides OB/GYN services for women of all ages. She loves supporting women through labor and delivery, and caring for women’s preventative health care needs and well-being. She also evaluates and treats gynecologic issues.

Her special interests include:

Her advice for patients is, “Focus on your happiness and everything in life will fall into place.” Warm, friendly and open, Dr. Terveen says her favorite part of her job is working with women, who are such complex, unique people—giving birth to life and breastfeeding children. “It’s such a privilege to care for women, from delivering babies through helping them in the older years,” she adds.

Active Lifestyle

In her free time, Dr. Terveen enjoys spending time with her husband and child. When not at the hospital or clinic, she can be found cooking, traveling, hiking, hosting get-togethers, gardening, and doing yoga.

Phenomenal doctor, I was very anxious for the procedure I was going to have and Dr. Terveen had reassured me and was very empathetic. Also had asked for additional service that was related to the procedure and the provider adapted very easily to the request. She was very transparent and detailed with expectations of the procedure and what would come after which eased a lot of concern. I would recommend her to anyone for her kindness, professionalism, and efficiency.

This is the first OB I have seen that has shown genuine concern for me. This is my fifth pregnancy. I was blown away with her knowledge, understanding, compassion, and willingness to listen. I can't express how grateful I am to have met the doctor.
