 Walk into the Grand Forks Clinic at 5750 South Washington Street, Grand Forks, or call 701-775-5800 or at grandforksclinic.com. Tom has been a teacher for over 40 years. One day, I think one of the students had asked the question and he didn't remember the answer. I also noticed that he was letting his class out earlier than they were supposed to let out. I was really starting to worry.
