Vanessa Lewis MSN, RN, CNOR


"My is name Vanessa Lewis I began my professional career as a medical-surgical nurse at University Hospital on the trauma unit and Wilford Hall in the Orthopedic Unit over twenty years ago. In 2001, I transitioned into the preoperative services at Methodist Hospital by having had a choice of being a nurse in the operating room or outpatient surgery. My first choice was becoming a nurse in the Operating Room upon starting I was placed in the AORN Perioperative 101 course. While at Methodist I was the Service Line Coordinator for Othropedic Spine surgeries, as my interest in leadership and management grew I became the Weekend Charge Nurse. This position allowed to go to school to complete my MSN in Administration, with a minor in Nursing Education and Nursing Informatics at the University of Texas Health Science Center. My nursing journey led me to the Veteran Administration Hospital where I was a Service nurse for podiatry, oral maxillary facial surgery, and GYN. I utilized my experience to serve others as the perioperative educator for the hospital always using the Preoperative Standards as my guide. Next, I transitioned over to the Nurse Manager Position, my units included Post Anesthesia Care Unit, Outpatient Surgery, and Interventional Radiology. My current role is with the Surgical Processes Services (SPS), where I am the Clinical QA Manager. This role allows me to keep the standards of AORN and Federal regulations by working closely with the operating room and keeping our veterans safe while they undergo procedures. I am currently pursuing my Doctorate in  Nursing.  

My service to AORN San Antonio includes being a Board Member, Secretary, Vice President and currently I serve as the President-Elect.  I look forward to the benefit of serving the AORN San Antonio Chapter."

Tom J stringer RN, BSN, CNOR


“My name is Thomas J. Stringer and I joined the San Antonio Chapter of AORN in December 1993 when I moved to San Antonio after retiring from the United States Navy after over  23 years of service. I chose San Antonio as a place to live partially because this is where I went to Nursing School at the University of Texas Health Science Center, San Antonio and partially because civil service jobs were available for my wife here.  We have lived here ever since and have enjoyed ourselves a lot. I earned a BS degree from West Texas State University in 1970 and a BSN in 1977 from UTHSCSA. I joined AORN after finishing the perioperative nursing course in 1986 and achieved CNOR status in 1989.  I like AORN because of the educational opportunities they offer and it helps one to be the best they can be. Their guidelines make it easier to know what to do and they have guided my practice throughout my career. I retired from full time practice a few years ago and have devoted myself to volunteer work since that time.  I volunteer at BAMC in the operating room now and with TIME for Christ, Refuge International, and with Mercy Ships. I make at least two medical mission trips a year with these groups if not more. I made four trips in the past year. 

I have served the San Antonio Chapter of AORN on the board of directors numerous times, as president for 3 1/2years as vice president for ½ year and secretary for 2 years and have served on every committee at some time.  I have chaired the legislative committee for a number of years now. I wrote the chapter newsletter and mailed it out for several years when we still had a printed form. I was vice president when the president and president-elect both resigned in January, 1999  at the same time because one took a job in Hawaii and the other in Arkansas. The board kept me on as president the next full term. I was president again in 2007-2008 and in 2015-2016.”

“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.”

Lori L. Minor BSN, RN

Board Member

Lori has been a member of AORN since 2015, when she began her career in perioperative services. She is currently a circulating nurse at Brooke Army Medical Center on Fort Sam Houston.


“The most important advice I received as a new OR nurse was to immerse myself in all things related to the perioperative field. My hospital educators suggested I become a member of AORN. Becoming a member has given me learning opportunities to gain more knowledge about the perioperative field, rather it be through continuing education or vendor demonstrations on products and equipment being used in my operating room. The ability to network and participate in open discussions with nurses from around the world about patient care in our constantly changing profession has been greatly rewarding.  The members of my local chapter have been the cornerstone and a tremendous support to my continued knowledge growth. It is my goal through mentorships to offer the same opportunities afforded me to other nurses, novice and expert."

“I love working in the OR and seeing the many changes that have taken place during my career. An example that comes to mind is endoscopic vein harvest, prior to that the patients would have a long incision that would take so long to heal, also the Davinci robot helps our prostates go home the next day and make the recovery so much quicker."

"I began my nursing career in 1968 when I graduated from a diploma program. During that timed I joined the Army student nurse program.  After graduating I worked in an all RN operating room and never had a job outside the OR for the next 48 years.  During my 20 year Army career I worked all OR positions and earned my BSN at the UT Health Science Center San Antonio in 1979 the same year I received CNOR.  After the military I worked contract for  28 years at BAMC retiring in 2016.   


 It is imperative our professional organization stay strong to fight the many battles that have and can face us again like keeping the RN in the OR, keeping a RN circulator, enforcing standards of practice, putting forward best practices for positive patient outcomes plus many other issues.  This responsibility belongs to each of us."
