Katherine Dang, Class of 2019

My spiritual relationship has grown through my time at Hallahan. I never felt more connected to God until I was here. I am forever grateful for the chance Hallahan gave me.

Hallahan Day was so much fun! I got to spend time with my big sister and friends. I can’t wait for next year!
