CREF speaker Summer Pizzuti CCP 2023 San Diego Perfusion Meeting

SPEAKER

Summer Pizzuti MBA CCP LP

 Summer Pizzuti is currently working as a full-time locum Perfusionist, self-contracting with her business, US Perfusion, LLC. She graduated from the Rangos School of Health Sciences at Duquesne University in Pittsburgh, PA with her Perfusion degree in 1999, working most of her Perfusion career in metro Detroit. 

As a locum Perfusionist, Summer has traveled across the US in the past 2½ years, covering the adult cardiac population from large academic centers to small community hospitals and everything in between. She has developed and maintained strong relationships with past co-workers and is often asked by former colleagues to come back and work with them again. 

Perfusion technology and techniques evolve over the years, and being flexible and open to learning is crucial for success in the operating room environment. As a traveling Perfusionist this is a sure constant. Over the years Summer has noticed that what is not taught in perfusion school is culture in the operating room; specifically, how to cultivate a healthy and positive culture in the operating room. 

In her off-time, Summer enjoys yoga, hiking, biking and spending time with her family and friends.

CREF 2023 keynot speaker Kenichi Tanaka MD

KEYNOTE SPEAKER

Kenichi Tanaka MD

I am a practicing cardiac anesthesiologist and Chair/Professor of Anesthesiology. My research focuses on perioperative coagulation management, transfusion and surgery-related outcome analyses. I have conducted a broad range of studies from laboratory-based ex vivo and coagulation device studies to clinical trials in cardiac surgical patients. My early work has extensively focused on viscoelastic coagulation monitoring devices, which subsequently led to their clinical application and research studies as part of bloodless surgery and patient blood management. I have obtained a Master of Science degree in Clinical Research during my junior years. and As PI or co-Investigator on multiple industry-, university- or foundation-funded grants, I have studied novel hemostasis monitoring methods, procoagulant and anticoagulant agents, and other means to modulate hemostasis and thrombosis. I am able to organize a group of investigators and other supports to conduct research projects in the field of perioperative hemostasis management.
