I had a situation and could not find a particular part number for Ultrasound. After exhausting all my options, I called Dick on his cell phone. After ringing a few times, he answered, and asked what I needed. I explained what part was needed, and he gave me the correct part number. He then said, he was in the middle of a class, and everyone was starring at him, waiting for the class to continue. I asked him, if he was in the middle of a class, why he answered the phone to which he replied; "Because you called me". That was my mentor; he was always there for me. I miss you every day, Dick.
