I've seen Dr. Hertel a number of times. I'm impressed with his ability to translate medical gobldy gook into language I can understand and use. He always seems to remember the content of past visits, impressive.  This is an aside. I've passed folks who saw me in their offices and nodded as they quickly continued their walk. Dr. Hertel was going to the cafeteria as I was leaving. His pleasant hi in passing was a warm fuzzy that made my day.
