Parents describe a free trial class that can be booked online, where a child’s name is displayed on a big sign and a free t-shirt is provided, and first-time students do a board breaking at the end of the trial class. For the first regular class, parents report that the student’s uniform is ready at the front desk. Families mention an app with categorized instructional videos that kids can use to practice, iPad check-in on arrival, after-class lollipops, and sticker stripes that lead up to different color belts. Parents also note flexibility of class schedules and an option to make up missed sessions with a personalized virtual class. In the Afterschool Pick Up program, parents report that the schedule aligns closely with the school district calendar, including minimum days and parent-teacher conference weeks with early pickups, and that time is set aside for homework, snacks, and physical activity. Multiple parent reviews mention patient and organized instructors, a positive atmosphere, and OMA’s presence and work in the Millbrae community.
