Quinta Brunson, Kaitlin Olson and More Stars at ABC’s Summer Soirée (Exclusive)

It’s September, which means your favorite shows are kicking off new seasons. To celebrate, ABC brought together all the stars from the network’s can’t-miss shows including Grey’s Anatomy, Abbott Elementary, High Potential and many more to mark the occasion.

ABC’s End of Summer Soirée, which took place on Sept. 5, at Cecconi’s West Hollywood in Calif., saw leading ladies like Quinta Brunson and Kaitlin Olson mix and mingle. There were cast reunions with the crews from 9-1-1 Nashville, The Rookie and Dancing with the Stars — and we have an exclusive look at all the fun.
