Mike is a doctor at the local hospital, where most of his patients seem to need treatments for either bites or sunburns. The townspeople are definitely a little strange, but they're in remarkably good health overall, so Mike has plenty of time to pursue his real passion: fishing! (which is the main reason he moved to Moonlight Falls in the first place.) Mike is teaching his daughter, Mara, to be a master angler. If he had his way, he’d go fishing every day.
He carries a medical beeper and a medical journal in his inventory. Mike is friends with his wife and daughter, and Joe MacDuff, and distant friends with Joanie MacDuff. When Moonlight Falls is first played, he is 15 days away from being an adult.
