“The 2023 class is our staff’s third recruiting installment and we couldn’t be happier for the direction of our program,” said Georgalas. “This group adds size, athleticism, talent, competitiveness and a championship pedigree to an already upward trajectory. The Brookings community will soon learn what great high-character individuals we’ve added to our program and we are confident they will all be tremendous ambassadors for SDSU in the future.”

At 6’4″, Brogan’s length and physical blocking presence will have an immediate presence in our gym. In addition, she is capable of scoring in multiple ways and her skill set will be a valued complement to her position group. Brogan’s passion for SDSU is resolute and we’re excited to add another South Dakota native to our program.”

Her character, work ethic, academics and overall standard for success will make her an exemplary leader at the next level. She possesses a great combination of athleticism and talent that makes her college-ready. A smooth release and a natural connection with her attackers should make for a seamless transition to our roster.”
