use the portal or make an appointment. Like it or not, an e-mail address is now pretty much an assumption, like a phone number, and one is going to be seriously inconvenienced by refusal to get and use one. There has been amazingly little pushback, and a lot of positive reinforcement.
Are all appointments made through the portal, or can they still call the secretary for one? Do you ever call about labs anymore, or just communicate through the portal? I'm always looking for ways to improve efficiency. Getting the portal really 'going' seems like an old tractor that is hard to start. You have to keep pulling the starter, and if you let it alone without attention for a while, it starts to die out.
