Board of Directors


Brittany Royal-Killam

I am a Texas born devoted servant leader who is dedicated in building long term business relationships with key decision making principals in the healthcare industry. I have been invested in the healthcare industry for over 6 years and I have worked with Payers, Providers and Integrators on a local level as well as a national presence.  I am experienced and successful technology professional that has cultivated partnerships with Fortune 500 companies on a regional and national level. I am driven and focused in investing in the success of our healthcare industry.

I have been engaged in HIMSS for over 6+ years from both a national and local presence. I recently served as the Membership Chair for the Louisiana HIMSS board. I believe that members are the core of the chapter and over my year term I grew to understand what the members need and value from their local chapters. I created exciting new ways to engage and share our events with all cities in the state of Louisiana as well as special programs geared to growing our chapter. I attended Chapters leaders hosted by HIMSS National where I learned valuable information and innovative process supported by HIMSS National. I have supported and participated in our tristate regional event that is hosted annually.  I have spent a lot of time collaborating with other chapters to learn from their success and see how we can implement new programs to create a greater value for our chapter. My value add for your chapter would be my many years of experience in the industry as well as my collaborative relationships with our HIMSS partner chapters to bring more value and new and exciting programs to your chapter. I believe the HIMSS organization provides a great platform for healthcare professionals to collaborate and innovate with one another and create conversations around trending topics.  It is an exciting time to be a part of San Antonio HIMSS and I would love the opportunity to help lead the chapter forward!
