Our Mission

The mission of Siouxland Obstetrics & Gynecology, P.C. is to provide high quality comprehensive and considerate women's health care with exceptional expertise and compassion. We strive to work personally, collectively, and collaboratively in guiding and empowering women with their health and well-being through every remarkable stage of life.

Our physicians are fully trained in using the da Vinci Surgical System at St Lukes Regional Medical Center or Mercy Medical Center.  da Vinci is a less invasive option now available here in Sioux City.  Some gynecology procedures enable surgeons to access the target anatomy using a vaginal approach, which may not require an external incision.  But for complex procedures, robot-assisted surgery with the da Vinci Surgical System may be the most effective, least invasive treatment option.  Through tiny, 1-2 cm incisions, our physicians can operate with greater precision and control, minimizing the pain and risk associated with large incisions while increasing the likelihood of a fast recovery and excellent clinical outcome.
