A Big Welcome to Our New Board Members

Trish Lindsey

Hello everyone, I’m Trish Lindsey and I work as an Operating Room Registered Nurse, specializing in the field of orthopedic surgery.

My commitment to improving the lives of those in need of joint replacement surgery is evident in my work with Operation Walk. During these missions, I volunteer my time and share my skills to help provide free surgeries to patients in developing countries. I’ve focused on working as an operating room nurse, particularly in the areas of orthopedics, neuro/spine, and behavioral health. The passion I feel for working in orthopedic surgery is matched only by my compassion for others. My life’s mission is to make a difference in the lives of those less fortunate.

Currently, I work as an Operating Room Registered Nurse at Keck Medicine of USC in Los Angeles. Prior to this, I worked at Northwestern Memorial Hospital in Chicago. With a career spanning over two decades, I have an extensive background in orthopedic surgery and an unwavering dedication to this field. My goal is to help to advance our organization’s mission of improving access to joint replacement surgery for those in need. 

I’m inspired by Brian Williams’ quote “You may find that making a difference for others makes the biggest difference in you.” I’ve always believed that it’s not what you have or even what you’ve accomplished that matters most. It’s about giving back by contributing what you can, may it be your time, skills or any small way possible to make a difference in someone’s life. 

Thank you,

Trish Lindsey RN BSN CNOR
