The parent support group Common Ground, which is affiliated with the Lighthouse Project and geared toward parents of teens and pre-teens, offers another free workshop to parents as part of the “Strengthening Mutual Respect” series. The subject of this evening’s 6:30pm workshop is titled “Understanding the Teenage Brain” and will be facilitated by Mark Hobbins, founder of online parenting resource FamilyIQ and co-founder of Aspen Education Group, which provides treatment programs for troubled youth and their families. To hear Hobbins’s 90-minute presentation offered by Common Ground, parents are asked to RSVP to 801-1766. The session begins tonight at 6:30pm at Community Church by the Lake and, though free, a $10 suggested donation would be welcomed.
