When I was looking for anesthesia residencies as a fourth year medical student from Chicago, I did a four week away rotation at UTHSCSA. I liked the program a lot and found everyone to be very friendly. My wife really wanted to move to Texas (San Antonio in particular). In fact, my wife matched for a psychology internship in San Antonio (separate match from me) and we spent a year apart while I did my medicine internship in Chicago. For anesthesia, I matched at Hopkins and we have spent the last three years in Baltimore and are looking forward to moving to Texas in July for my new attending job.
Sometimes I think about the road "not traveled". My wife and I could have been living in a very nice house in San Antonio for the past three years instead of an apartment in the suburbs of Baltimore. While Baltimore winters are better than Chicago winters, San Antonio winters are very nice.
The private practice environment in San Antonio in my opinion is not ideal. It is mostly follow the surgeon model with Tejas and Star. If that is your style, then I guess it is fine, but I prefer a hospital/group based model. I'll be honest, coming from Hopkins, I was able to get interviews at just about every place I made an inquiry and got an offer from every place I interviewed in Texas.
The new chairman, Dr. Andrews, is a great guy. I interviewed with him when I was looking at UAB when he was the vice-chairman. I think he will do great things for the department. However, unless you want to stay at UTHSCSA or work in the follow the surgeon private practice model, you will have to leave San Antonio after residency. That said, San Antonio is a very nice place to be for three or four years. Like all things in life, you have to find the best fit for you.
