He figured out what was wrong with me within 5 minutes. It stumped my primary care physician, but thank goodness he sent me to Dr. Alexander. This man is smart, easy-going, friendly and very funny, if you like a wry sense of humor ( I do). I had some questions after the follow-up app't and he returned my call within a couple of hours. His staff is very friendly and professional. I was quite impressed, and believe me, I'm not easily impressed.
