I called Dr. Kline's (LSU) office today in my search for someone who has a clue. His office told me that he has retired, but they are referring TOS patients to Dr. Daniel Kim (Houston Baylor). Dr. Kim was trained by Dr. Kline.

This was a great relief to find someone who had been trained in TOS. I meet with him next week. Hopefully this information will be helpful to others.
