    Welcome to Texas Society of Anesthesiologists


    It shall be the purpose of the Texas Society of Anesthesiologists to advance, promote and support the practice of the medical specialty of Anesthesiology in the State of Texas.

    The TSA is a voluntary, non-profit association of over 3,800 members interested in the medical specialty of Anesthesiology and it is a component of the American Society of Anesthesiologists.

    TSA provides CME programs; advocates at the legislative, regulatory and legal arenas; and through its representation at the ASA, TMA, and AMA, it insures that TSA’s voice is heard at the state and national levels.

    TSA President Dr. David Bryant

    We are in unique times as we are amid the Covid-19 pandemic. The very fabric of practice in Texas was disrupted. We have many challenges for the coming year.

    As incoming president, I get to offer my thoughts on hope and what gives me optimism for the future advancement of our specialty and humankind despite the obstacles for each.

  • Dr. Evan Pivalizza

    TSA Past President Dr. Evan Pivalizza

    I trust that I have been able to advance the goals of this great organization and I am excited about our future after a most challenging year.

    I eagerly look forward to Dave Bryant’s guidance and leadership as incoming president and pledge my continued support to the TSA.

Charles Cowles 

It is with deep sadness that we inform you of the passing of Charles E. Cowles, MD, MBA, FASA, FAACD

Dr. Cowles and his family were traveling to Missouri to see family when they were in a vehicle accident. Charles was a staff physician at M.D. Anderson Hospital in Houston, served as our TSA Assistant Treasurer, and has served on numerous TSA committees since joining the Society in 2005. He was an outstanding physician, friend, and faithful servant to the Lord. Dr. Cowles’ wife and three sons are being treated for injuries and will be returning to Houston soon. Obituary details are not available at this time. We will update the TSA website as information becomes available. We ask that you keep the Cowles family in your prayers.
