He was my professional and personal mentor, my teammate, and my friend. He and I worked together for a number of years early in my career. He challenged me to be the best nurse and set expectations for everyone we worked with. He was an influence to so many of the patients we supported. He never missed an eagles flight and was a constant on the ropes course. He taught me the subtle art of observation and how that gave us a better picture of the patient. He helped me through my divorce and later attended my wedding. I have and will always value his teachings, encouragement, and guidance. Joe will always be the one who set the bar that the rest of us tried to achieve. We went to amazing restaurants and he shared his love of great food and even better company. I miss him dearly.

Our offices were next to each other for 13 years. We were comrades in the true sense. Professional discussions, sports discussions, grandkid bragging, and the same bathroom. We both celebrated a new commode like a new toy for a kid. He turned me on to the best Italian food in Austin. I was happy for him when he retired but not for me. I missed him a lot and will now even more. Rest in peace Joe. From a friend.

Joe has always been a wonderful person to work with and has contributed to my professional growth, as well as in so many ways my personal growth.

I have fond memories of collaboration on cases with him as well as cherished Longhorn events he was so gracious with sharing.

Thank you Joe for all you have done for countless others. A life well lived, and like ripples in a pond, effecting the lives of so many.

I am better for having known you.

Rest easy, Dr. Simpson. The impact you made on young clinicians will live on forever. We were all so lucky to be taught by you, and honored to have been a part of your treatment team. I have lots of memories of you, but my favorite is you sharing pictures of your grandkids to us. My prayers are with your loved ones at this time.
