The Minyan at home is at 7 AM and I possibly will miss my doctor appointment if I stay for it. The question is should I  daven alone without a minyan and then go to the appointment, or can I travel to my appointment and then daven with a Minyan before the end of the zman? Answer: You can travel to the appointment and then Daven later with a Minyan, just first recite Brachos before you go.
