I actually told a friend that a new doctor had joined the staff here. She had an appointment with him and liked him. When Patricia Heffner couldn't see me soon, I made an appointment with him and I liked him also. At my age it was like seeing Doogie Howser, but I didn't feel like he wasn't capable.
