Summer Schedule Our last day of playgroup at the church will be Thursday, June 1st. Beginning on June 2nd, The Family Club will gather at Cahill Park in Whitefish Bay on Fridays. Cahill is located on the 4900 block of N. Marlborough Drive. Look for Family Club friends on Friday mornings during the summer. Stay and play for an hour, or pack a picnic lunch and stay all morning.
