There are Weekday Masses as early as 5:30 a.m. and as late as 7:00 p.m. on different days during the week. As the availability of these early and evening Masses may change based on the schedules of the priests, the best source of information regarding these Mass times will be the weekly bulletin.
Also, see the Chapel App at fsspx.today for Mass times here and at other SSPX chapels in the US and also in Canada, Germany, Austria, and Belgium.
