When Theo was very little, doctors weren’t sure he could overcome his challenges to engage in a full HS curriculum.
Today, he presented his senior capstone at SLA - a 50 page paper that showcased his passion for music and social justice.
And thank you to all his classmates who showed up for him.

SLA boys played in a VERY high level tourney this weekend. Went 2-4 - three losses were against Top 25 teams.
But the wins were sweet, including this 10-9 win over Harriton HS. We scored the game winner by forcing the turnover and then working it upwind to score.
Amazing play by both teams.

The Trump White House believes that the crueler, the more mean-spirited they are, the more popular they will be.
They don't even want to be benevolent dictators.
They simply want to be as cruel as they possibly can.

The unelected, unvetted, untethered billionaire has just changed his screen name to “Hairy Balls.”
This is all a joke to them. You, me, the lives we lead, the work we do.
They don’t care. They will burn it all down for two reasons:
1) Lining their pockets.
2) Because they can.

At least we know why they took the Constitution off the White House website…

They have no interest in the rule of law.
