InSytu was born in 2008 as the donor funded Gossman Center for Pediatric Simulation at Swedish Medical Center in Seattle, Washington.    A state of the art simulation lab led to expansion of scope beyond pediatrics to obstetrics, emergency medicine and other high risk areas. 

We soon learned that simulation outside of the lab in areas where patient care actually takes place led to mitigation of latent safety hazards and that using realistic multidisciplinary teams practicing high risk, low frequency events together allowed the caregivers to improve their practice while learning with and from each other.   Moving outside the lab setting allowed us to grow our simulation practice to support the entire Swedish system and eventually working outside our home as InSytu.  In 2015 we began a pioneering system wide set of OB emergency simulations across the greater Providence system (30 sites) to facilitate a standardized evidence based approach to managing high risk emergencies, the largest program of its type. 

We have partnered with dozens of hospitals and health systems across the United States, helping engage their bedside caregivers in improving outcomes, decreasing risk and cost improving their work caring for patients.

Theresa Demeter, Mha, Executive Director

I have enjoyed more than 25 years’ experience in healthcare leadership, management and education. From leading Women and Infants Outpatient Services and the design and development of The Lytle Center for Pregnancy and Newborns at Swedish, to the transformation of InSytu, I understand and am passionate about the importance of empowering and supporting caregivers to provide the very best care for patients. Since 2012 I have been driving the strategy and development of InSytu into a nationally recognized leader in onsite simulation and process improvement. I am very proud to lead a group of physicians, nurses and technology specialists who are dedicated to our mission. I am an active committee member of the Society for Simulation in Healthcare and the Healthcare Business Women’s Association.


Ian Doten, MD, FACEP, CHSE, Executive medical director

I am a practicing emergency medicine physician and have seen firsthand how onsite, multidisciplinary simulation helps teams of caregivers function at the highest level.

As a former medical director for two busy emergency departments and a system chief of emergency medicine, I know that standardization across different care areas to meet institutional goals and process improvement is always challenging, and I’ve seen our system use the strength of its bedside experts to design care that works for the whole team, and most importantly, for our patients.
