Mary Garison
Immediate Past President

I am blessed and honored to have the opportunity to serve you as your TSAOHN President for 2018-2019. I have had the honor to serve you as an AAOHN and TSAOHN Director. For the past 20 years, I have been active with our National, State and local chapter and have worked diligently in addressing the issues of our organization. I advocated for and contributed to strategies and programs that were developed to outreach chapter leaders and provide opportunities for sharing and problem solving. My commitment for TSAOHN is to strive for and promote excellence among our members. My vision is to have well prepared occupational health nurse leaders who will lead our members in meeting the challenges of new future changes and demands. I am enthusiastic and excited to partake in the work of the Board of Directors. I will work relentlessly on your behalf to elevate our profession and to ensure the state and national support is provided to each member and to the chapters. You are our most valuable resource! As an individual chapter level, your membership strengthens our association and promotes our credibility and value as a profession. I am honored and looking forward to serving you as your TSAOHN President. I pledge to do my best in representing you with pride and integrity, to be your voice in taking appropriate actions in addressing your concerns and continue to mentor OHN’s

Kevin Bready
Treasurer / NTAOHN Chapter President

I have been involved with AAOHN, TSAOHN, and NTAOHN for a shorter time than most of the other directors, but have strived to be an active participant at all levels advocating for the advancement and maintenance of our profession. I was a non-traditional nursing student having first started my medical career as a paramedic. While a medic, I had my first experiences in Occ health while working in the offshore oil and gas industry, I quickly made the decision to return to school to become an RN hoping eventually to transition back to Occupational Health, seeing it as an avenue to make a larger difference. Having also worked as an ER nurse, ICU nurse, and in surgery – I have combined those skills and resources to provide my employer and this organization with the best of my skills, abilities and judgement. I am a lifelong learner and come to this position with a collaborative spirit that is results focused. I am pleased to be working on your behalf for TSAOHN and look forward to the projects at hand. As the Government Affairs / Policy & Procedures/Bylaws Director; if there is a way I can help you please contact me at; I am interested in your thoughts, concerns or direction.

Hilda Wist
Secretary / HTAOHN Chapter President

This is my 50th year celebrating my career choice as a nurse. For me, the luster has not worn off. Currently, I serve in the capacity of the nurse manager for the Enbridge Corporation Health Center, a satellite clinic of The University of Texas.  I am the only nurse practitioner for The Enbridge Corporation, both in the United States and Canada. I have been a member of AAOHN, TSAOHN, and HTAOHN for 20 years. I am grateful and honored for all the mentoring that I have received from the Great Leaders in this organization. It is now my opportunity to give back. It is my goal to unify our efforts as occupational health nurses to elevate our profession to further heights. It is a privilege and a pleasure to serve as President of HTAOHN and Secretary for TSAOHN.
