Office Information

About Me

Whether you love running marathons, sit at a desk or attend school, Dr. Anita Inveiss is dedicated to serving patients of all ages, backgrounds and health goals. She practices thorough and compassionate care at Avera Medical Group Gregory in Gregory, SD.

“When I first toured the Gregory health campus and community, I immediately liked the area and the people,” remembered Dr. Inveiss. “I saw myself living there and serving patients there.”

Comprehensive Primary Care

Primary care touches nearly all aspects of health care. From handling mom’s health before the birth of her baby to sports physicals, from follow-up care after surgery to managing chronic conditions, family medicine providers care for all ages and stages of life.

Not only did the aspect of helping people attract Dr. Inveiss to the medical field, but also the variety of situations she can explore with her partner in health, the patient.

Her special interests include:

  • Routine checkups
  • Sports physicals
  • Immunizations
  • Chronic disease management, such as diabetes and blood pressure
  • Preventive medicine
  • Mental health care, including depression and anxiety

It’s About People

The best part about her job is interacting with patients, as well as offering life-changing health education. By teaching preventive measures, she enjoys seeing people making healthier decisions in their everyday lives as well as taking the initiative to schedule regular exams.

"In order to set up an effective doctor-patient relationship, we have to get to know each other personally — talking about our lives, interests and loved ones,” said Dr. Inveiss. “Then we can talk on a deeper level, discuss concerns and come to a mutual treatment plan."

Active Lifestyle

Dr. Inveiss is married, has two grown children and their family also includes two energetic Brittany spaniels. She’s a diehard Green Bay Packers fan, and enjoys reading non-fiction books, going for walks and traveling. For six and a half years, she also served in the Navy as a physician. 

She and her husband are devoted to their Latvian heritage; in fact, they only speak Latvian at home. When she was younger, she attended Latvian school every Saturday until 8th grade (regular school Monday through Friday), and then attended a Latvian summer high school in Michigan.
