About Me

The interest of becoming a physician came to Lauren O’Brien, MD, when she was a child. In fact, it seemed like family knew as well; as a kid, she enjoyed putting bandages on people. Later, when she was in medical school, she was involved in the delivery of a baby — and she’s been hooked ever since.

Today, Dr. O’Brien provides expert and compassionate care to women of all ages as a board-certified obstetrics and gynecology physician at Avera Medical Group Marshall – Bruce Street in Marshall, MN.

Services for Women

Dr. O’Brien provides a number of services, some of which include:

  • Annual women’s health exams, including Pap tests and caring for menstrual irregularities
  • Gynecologic surgery, including minimally invasive laparoscopic procedures
  • Labor and delivery
  • Pregnancy planning and care

A Journey of Health Care for Women

Dr. O’Brien enjoys being part of the pregnancy and birth journey of her patients. One of the most rewarding experiences is walking through the entire process with women — from the decision to become pregnant and the prenatal care to the actual delivery as well the follow-up appointments with baby.

Active Lifestyle

Dr. O’Brien used to play softball in college, so she enjoys going to the field now and then. She also likes going to the movies and reading.
