“Foundation is so important when I look back at my Perioperative career. The foundation laid by AORN, implemented by the hospital, directed by my perioperative educator and OR Staff has served me well to this very day. This foundation has helped me to have an extraordinary OR life.  Being a part of a team that can change the trajectory of someone’s life is truly an honor. AORN is important to me because it has helped and continues to set the benchmark for patient safety as well as the Standards that we apply to every patient every time as they enter our OR’s.”

"I believe that perioperative and peri-procedural nurses have the ability to impact the lives of their patients and their family members at some of the most vulnerable times in their life. For many, a medical and surgical intervention(s) can be a significant life event and every aspect of that medical care can have a profound impact.  In some case this can affect them for a lifetime.  Because our profession and the perioperative nursing specialty is continuously evolving it  requires nurses to seek up-to-date information and continually educate themselves with relevant information in order to provide the very best to their patients.  That is why AORN is so important to me.  It has always been at the forefront of bringing its members recommended practice standards, evidence-based practices, new trends and treatments in surgical and procedural care through a variety of venues. I feel fortunate, organizations like the Association of periOperative Registered Nurses (AORN) diligently works to collect and disseminate the latest innovations and best practices in perioperative nursing so we can be the best at what we do.”

Board Member

"I have been in Nursing for over 40 years of which over 30 were in the peri-operative setting. I joined AORN in 1983. My mother was in Nursing, so It has played a big part of my life. When I started school in the 60’s, not getting in the school of my choice, I went into education getting a BA degree. 

Later I became an LPN , then AAS degree in Nursing and a BSN. Working in different areas of Nursing , the Operating Room was where I wanted to be. I had to wait 2 years to get in as there was little turn over of staff. Early on I discovered I liked being a patient advocate and working with a team where there is collaboration to obtain the goals set for our patients. My last 3 years were in Central Sterilization, an area attached to the OR where sterile instruments were easy to get to. Without this department, there can be no Surgery. As an periOperative Nurse it’s important to attend our yearly Expo which is held in different cities throughout the US, to network, see new products on the market and get education benefits. Although  retired, I try to attend , and alway see products / equipment I didn’t have when I was active in the OR. 

I now teach hand washing to first graders in an elementary school twice a month. I also teach at my church. I also do other volunteering at our Military Hospital. All of this is rewarding as a retired Nurse."
